Note
Switches to High
Crocus magnetic switches provide high stability
as well as highly reliable performance over
a wide range of operating temperatures and
voltage supply.
2
Switches to Low
The Crocus series of magnetic switches is
composed of multiple magnetic tunnel junctions
(MTJs) made of magnetic thin films. The MTJ cell
is constructed of two magnetic layers separated
by a thin oxide which serves as a tunnel oxide.
One of the two magnetic layers has a fixed
magnetic orientation and it is called reference
layer. The other magnetic layer, called sensing
layer, has flexibility of changing orientation in
the presence of magnetic field, leading to the
change of the sensor resistance. Thus, the sensor
acts as a magnetic switch whereby it shows high
resistance when magnetic field is absent and low
resistance when magnetic field is present.

The Crocus CTSR400C series is a family of
magnetic switches designed for sensing a
wide range of magnetic fields. The advantages
of the CTSR400C series include high magnetic
sensitivity, no bias current, low power
consumption, flexible supply voltage, small
form factor, and low cost.

Melexis Unveils Software-Defined Sensor
Ultra flexible, magnetic sensing solution gives engineers carte blanche
in HMI implementation through breadth of programmable parameters.
The MLX90393 is a micropower triaxis magnetometer and is offering
maximal flexibility at minimal size. With its 3 x 3mm footprint, it can fit in
the tiniest of assemblies. It provides a digital output proportional to the
sensed magnetic flux density along the 3 perpendicular axes of symmetry
of the sensor. But the miniature sensor is mostly characterized by the fact
that it can interchange measurement speed for both current consumption
and noise on the digital output signal, making it the raw building block for
any magnetic sensing application up to +85°C. An external microcontroller
can then combine the measurement data in order to define the position of
the magnet with respect to the sensor. All that at a selectable duty cycle of
0.1% to 100%.
•Micropower (2.2V to 3.6V, <5µA idle current)
•Low voltage I/O (1.8V - VDD)
•SPI (3+4-wire) and I2C interface, slave node
•16-bit XYZ magnetic and T thermal measurement
•QFN 3 x 3 package, 16-leads
•In-application programmable (gain, mode, axes, …)
•Ta = -20°C to +85°C
APPLICATIONS
•Sensing element for the Internet of Things (IoT)
•Metering
•Impeller-based meters 360° impeller position detection incl.

Human Machine Interface (HMI)
The MLX90393 lends itself to a wide variety of HMIs such as joystick
(Gimball, Ball&Socket) with push detection, rotary knobs with push
function and linear strokes by levers or sliding switches. The sensor output
data needs to be post-processed in order to calculate the angles or norms of
the vector in order to get the desired position signal(s). This requires
off-chip computation, and is a clear advantage in system level partitioning
by having one microcontroller interfacing with many sensors on the
same bus.
The MLX90393 supports 3 different operating modes:
1. Single measurement mode
•Command-based
•Trigger-based
2. Burst mode
3. Wake up on change mode
In single measurement mode, a bus master is requesting the sensor to
perform a measurement, either by transmission of a command, or by
issuing a trigger signal.
Whenever the sensor is in burst mode, it is waking up and going back to
sleep at an in-application programmable duty cycle.
Finally, the wake up on change function offers the same functionality as
the burst mode, but only setting the interrupt pin high whenever the latest
measurement differs more than a programmable threshold from either the
previous measurement or the first measurement when entering the mode.

Accurate Current Sensing: How it Helps to Keep a Car’s Battery Healthy
By: Chris Lohmeier, Development Engineer, Vishay Dale (Resistors Division)
It’s a normal school night. You are driving
across town on a dark, snowy evening to pick
up your child from after-school practice. You
have the radio blaring and the navigation
system on – you never turn them off. It’s a
cold night, so the heater fans and seat warmers
are running at their highest level.
You pull up to a red light, and the car’s automatic stop-start system shuts the engine off to
conserve fuel. When you hit the pedal to move
off, however, nothing happens. You try to start
the car manually, but the starter just whines and
the headlights go dim.
What’s happened? All the fancy features and
new technology in the car have drained its battery, and now you are stranded in traffic with a
child waiting for you across town.
This scenario is all too familiar, and is becoming
more common as new vehicles come equipped
with an increasing number of innovative systems
that rely on the one component of the electrical
system that has seen almost no innovation since
the 1950s: the lead-acid battery.
Lead-Acid Battery Technology
The lead-acid battery has been an integral
part of a vehicle’s electrical system since 1912;
Cadillac was the first to harness its power, and
turned the automotive industry upside down by
introducing the self-starter. And the lead-acid
battery is still the most viable energy-storage
unit for vehicles, because of its performance,
ruggedness and low cost.
Many different technologies have been mooted
as replacements for lead-acid; all have been
either too expensive, too fragile or too large. It is
12
true that the lead in car batteries is highly toxic.
But the environmental concerns are mitigated
because lead is the most recycled metal in the
world. It is estimated that some 97% of all
battery lead in the US is recycled.
car goes straight from starting to idling in traffic,
the reduced engine speed will not allow the
alternator to adequately recharge the battery.
If the motor is not allowed to speed up, the
battery dies.
Unfortunately, improvements to the lead-acid
battery have not been anywhere near able to
keep up with the technological advances seen
elsewhere in cars and trucks. According to the
2010 Battery Council International Technical
Subcommittee, which conducts studies to find
the failure modes in recently removed batteries,
plate/grid-related failures had actually increased
by 9% compared to five years previously. It is
generally assumed that this increase in failures
is caused by the extra electrical stress on the
battery caused by the increase in the number of
electrical systems in new vehicles.
Stratification may have the same causes as
sulfation. It occurs when the battery is held at
a low state of charge, only moderately cycled
and never fully charged. While the cause may be
the same, what happens is very different. In a
stratified battery, the electrolyte separates from
the liquid mixture contained within the battery,
and accumulates in the lower regions of the
battery. The light acid in the upper regions
causes the plates in these areas to be more
likely to succumb to corrosion, while the highly
concentrated lower region causes sulfation on
this section of the lead plates.
Why Lead-Acid Batteries Die
In addition to the long-term effects of corrosion
and sulfation, stratification causes short-term
effects in the form of reduced cranking
performance when starting the car. Stratification
also causes the battery to have a false rise in
the voltage reading, which makes the battery
look more charged than it actually is to most
measurement systems.
There are three main causes of lead-acid battery
failure. They are corrosion, sulfation, and acid
stratification. They result from over-charge
conditions, under-charge and abuse, respectively.
Corrosion is when the lead plates break down
over time; eventually, portions of them might
deteriorate completely. Corrosion of the lead
plates in a battery is inevitable because they are
immersed in acid. This process accelerates when
conditions such as over-charging, high depth of
discharge and over-temperature occur. The key
to extending the life of a battery is not to stop
corrosion but to manage those causes of it that
are controllable.
Sulfation occurs when a battery is not allowed
to be fully charged. This is a condition that has
been made substantially more common by the
increased number of electronics systems in new
cars. After starting a vehicle, the lead-acid
battery needs time to properly recharge. If the
Keeping a Car Battery Healthy
The natural question resulting from this explanation of lead-acid technology is, how can these
modes of failure be prevented from happening?
The sad answer is that they cannot. These
failures will inevitably occur, and even under
the best of operating conditions the battery will
eventually die from corrosion.
Early death, however, can be prevented. What
is more, the driver can be notified of impending
natural death if the vehicle is provided with a
sophisticated Battery Management System
(BMS).
1.800.675.1619 • www.FutureElectronics.com
DESIGN NOTE
A BMS will be able to accurately monitor
all battery parameters, including current,
voltage and temperature. If the device is unable
to monitor all of these parameters it will not be
able to identify whether a battery is in good or
bad health. For instance, the increased voltage
caused by stratification will be misleading to
a meter that only considers voltage measurement when determining a battery’s State of
Charge (SOC). The BMS should take these three
measurements together, and provide them to
a higher level controller for an estimation of SOC.
The SOC is basically an estimation of how much
energy is left in the battery. Like a vehicle’s fuel
gauge, it shows how ‘full’ a battery is. The SOC
can be calculated by coulomb counting. Coulomb
counting is a method of measuring the current
into or out of a battery, and integrating it over
time. If the battery’s capacity is known, it is
simple to calculate how full it is.
In the case of automotive batteries, however, it
is not so straightforward. This is in part because
corrosion and sulfation occur throughout the life
of the battery. This means that a battery will be
losing capacity over its entire life span. Therefore
a fully charged battery will not contain as much
stored energy after a few years of service as that
same fully charged battery when it was new.
State of Health (SOH) readings help the measurement system to compensate for this decline
in capacity over time. An SOH value gives an
estimation of the percentage of the original
maximum capacity. A new battery would have
an SOH of 100%, whereas an older battery
might have an SOH of 85%.
If an older battery is fully charged it will show a
full SOC. Since it is older, however, the maximum
that the battery can be charged to is 85% of the
original capacity, meaning that even though the
system says the battery is full and the charging
system stops as it should, the car will still know
that the SOC level will fall more quickly since it is
being measured on a smaller scale. SOH estimations made with a good BMS thereby remove the
false capacity readings that other measurement
systems might produce.
Using Information from a BMS
So how could the scenario presented at the
start of this article have been prevented by the
use of BMS data? A BMS would monitor the SOC
and SOH of the battery. Therefore the vehicle
could have turned on warning lights or alarms
weeks or months before the battery died on
that night.
Of course, drivers routinely ignore warning
lights. So the system could have sensed imminent
danger and shut off non-essential systems (such
as seat warmers and radio) to help maintain the
battery’s SOC. In addition, the vehicle’s control
system would have prevented the car from
shutting off the engine at the red light, given
the risk that it would not start up again.
Vishay Dale Intelligent Battery Sensor
An example of an ideal sensor for use in an
automotive BMS is the Vishay Dale Intelligent
Battery Sensor (IBS). The Vishay Dale IBS
measures the voltage across the battery’s
terminals, the charge or discharge current
flowing through the battery, and the temperature
of the battery measured through thermal
conduction between the battery post and the
IBS unit itself, using a WSBS8518L100 shunt
resistor (see Figure 1).
All three measurements are taken almost simultaneously to ensure accurate measurements even
when operating conditions are changing rapidly.
The Vishay IBS uses a LIN communication protocol
to send the results of these measurements to the
vehicle’s ECU or other control systems

IBS to survive conditions that would damage
even the newest lead-acid batteries. The voltage
measurement range lets the unit continue to
retrieve data under both battery over-charge and
under-charge conditions. Through proprietary
software the device is able to monitor the full
current at both ends of the voltage and
temperature extremes, with minimal loss
of accuracy.
Conclusion
Future automobiles will continue to have more
and more electronic systems that will make it
even harder for the lead-acid battery to maintain
the correct output over many years of reliable
operation. A high performance BMS provides
both the driver and the vehicle’s control systems
with the information they need to prolong the
life of the battery and to manage the risk of
failure effectively.

DESIGN NOTE
How New Regulations for Power Supplies Affect the Design of
Home Healthcare Equipment
By: Lorenzo Cividino, Director of Field Technical Support, SL Power Electronics
Phenomenon
Regulatory changes in the medical industry
take place at a slow but steady pace. In the
past few years, however, several updates to
the medical safety regulatory standard based
on IEC60601-1 3rd edition have been brought
in. This primary standard also has collateral
standards, one of which defines the requirements for electromagnetic disturbances and
compliance (EMC) requirements.
Then in February 2014, the IEC issued the 4th
edition of IEC60601-1-2, ‘General requirements
for basic safety and essential performance –
Collateral Standard: Electromagnetic disturbances
– Requirements and tests’. Under review by the
nations of the European Union, it is expected
to be adopted in or around 2016 as a European
Norm (EN standard).
This marks an important change: designers of
medical equipment should certainly plan ahead
and prepare for its introduction, as it will have a
noticeable impact on the professional and home
healthcare markets.
The force of the changes will be felt particularly
strongly in the areas of:
•AC input-voltage power drop-outs
•ESD immunity
•Susceptibility to electric and magnetic fields
For power supplies used in medical devices, the
main changes in the IEC60601-1-2 4th edition are
shown in Tables 1 and 2.
The MB65 AC/DC power supply from SL Power
Electronics was developed to provide system
designers with an easy means to achieve
compliance with the new 4th edition standard.
It is especially well suited to home-healthcare
equipment.

and from 8kV to 15kV (air discharge). Clearly,
the regulatory bodies have recognized that new,
high levels of ESD may be generated by the
synthetic and natural materials used in the home
and in professional institutions.
In particular, the continuous AC input range now
goes to 85VAC, down from 90VAC. This offers
extra margin for home healthcare environments,
in which power quality is variable, and less well
controlled than in hospitals and clinics.
The MB65 also meets the emissions requirements
for home health environments; in fact, it stays
inside the threshold for conducted and radiated
emissions for Class B compliance with a margin
– no small accomplishment (see Figure 1). This
simplifies the design of medical equipment at
the system level, since it eliminates the need
for external components or circuitry dedicated
to filtering or shielding Class B emissions. This
can provide worthwhile cost savings in the end
equipment.
Another area seeing a noteworthy change is in
the level of ESD protection required. This has
increased from 6kV to 8kV (contact discharge),
Designed for long life, the 65W MB65 has a
compact 2” x 3.5” footprint. It provides a high
output power with convection cooling, and

offers excellent safety isolation, including two
means of patient protection (type BF).
This model family is also designed to operate at
higher temperatures up to +70°C while still
providing 40W of continuous output power.
While supporting this high output, careful
attention was paid to power losses, since these
1.800.675.1619 • www.FutureElectronics.com
DESIGN NOTE
serve to limit product life and maximum operating
temperature. In order to achieve power density
of 7W/in3 and still allow for up to 65W of output
power with convection cooling in such a small
unit, power conversion efficiency needed to be
maximized.
The efficiency of the MB65 is as high as
88% to 90%, which lowers power losses. This
in turn markedly lowers the scale of the internal
temperature rise in normal operation, and also
reduces the requirement for cooling.
In fact, power losses from the power supply are
the dominant source of heat that raises internal
temperature. Figure 2 shows the power losses
for different power supplies: one with 85%
efficiency, a second with 88% and a third with
90%. While the 3-5 basis point difference in
efficiency may not seem important, the better
comparison is that in power losses. The more
efficient product has 30% to 37% lower losses.
The less efficient products have a higher internal
temperature because of their higher losses,
and the reliability and expected life of the more
efficient product will be much higher.

The curve in Figure 3 plots the temperature factor
for failure rate. It can be used to determine the
failure rate difference when comparing operating
temperature conditions. For example, at +70°C,
πT = 6.0. If you were able to reduce the operating
temperature to +60°C, π T = 4.0, so the failure
rate would drop to +66.7% of that at +70°C.
While the product failure rate is a function of
many variables, there is a marked impact from
reducing the temperature of components.

electrolytic capacitors and power semiconductors

Temperature and failure rate
In general, devices and components fail faster
at higher temperatures. The expression below
shows the temperature factor as a function of
temperature with respect to +30°C. It is a nonlinear function, and clearly shows the dramatic
impact temperature has on component failure
rates. For example, the failure rate is 1.6 times
higher when operating at +40°C than at +30°C.
Temperature factors, π T are derived by the
following expression:
Product operating life is often determined by
its life-limiting components such as electrolytic
capacitors. The failure mechanism of electrolytic
capacitors is the loss of capacitance and increased
ESR as the electrolyte seeps out through the end
seal of the capacitor. High temperature accelerates
this process. The following expression has been
experimentally determined to express the relationship between temperature and deterioration
of the capacitor.

Figure 4: electrolytic capacitor life estimate, life factor as a
function of capacitor temperature
Based on a +105°C rated capacitor, at its +105°C
rated operating temperature and base life, KT
Factor = 1. At +70°C, KT Factor is = 11.3, so for
a 5,000 hour rated capacitor, operating at +70°C,
its rated life is 65,500 hours, or approximately
6.4 years. The life of the capacitor is strongly
affected by its operating temperature. For
products requiring long operating life, long life
(5,000 to 10,000 hours) rated capacitors should
be selected, and their operating temperature
kept to a minimum.
In the MB65, high-quality components are used
at relatively low operating temperature, since the
high conversion efficiency of the power supply
keeps power losses to a minimum. This model
family is also designed to operate when necessary
at higher temperatures up to +70°C while still
providing 40W of continuous output power.
In fact, the MB65 leads the way for reliable,
compact power at a competitive cost while also
compliant now with the EMC requirements of the
4th edition of the IEC60601-1-2 standard.

Reliability
The URG series, like its cousin RGLL, boasts the
industry’s best absolute tolerance ±0.01%, and
smallest TCR ±2ppm/°C, as thin film chip resistors.
Because it is made of thin film, it maintains all
the thin film advantages such as low noise
(-25dB to -35dB) and frequency performance
(up to 1GHz). In addition, the URG series shows
superb linearity in TCR as shown.
The RG series has excellent reliability and the
URG‘s reliability is even better. For example,
the maximum drift for load life (+70°C, 2000
hours) is specified as ±0.02% (RG ±0.05%),
the humidity bias (85/85, 2000 hours) drift
is specified as ±0.05% (RG ±0.1%, refer
to the graph), the temperature cycle drift
(-65°C/+150°C, 100 cycles) is specified as
±0.02% (RG ±0.1%), and the high temperature
exposure (+155°C, 100 hours) drift is specified
as ±0.02% (RG ±0.1%). The URG series is also
highly stable under any environmental conditions
including sulfuric atmosphere.
