At Infineon, we strive to make life smarter, safer and
greener, with our sensors being one of the key elements.
As a broad-line supplier, Infineon provides the broadest
magnetic sensor portfolio in the market, for instance. We
are one of the leading sensor suppliers for automotive
applications, as demonstrated by the fact that we are No. 1
in many applications such as wheel speed and side airbag
pressure sensors, along with radar chips.
As a strong partner for sensor solutions, Infineon draws on
40 years of experience in sensor design and production. We
have sold more than four billion integrated magnetic and
pressure sensors in the last 10 years, supplying automotive
and industrial markets with more than two million sensors
per day.
At Infineon, we are committed to making cars safer, smarter and greener with our innovative and leading sensor
portfolio. Today, a new car features numerous safety, body
and powertrain applications that rely on magnetic sensors.
Clearly focused on future trends, our outstanding portfolio of sensor ICs for numerous safety-relevant automotive
systems makes cars much safer. In Electric Power Steering
(EPS), our magnetic angle sensors and linear Hall sensors
are used to measure the steering angle and steering torque.
Since all our newly developed parts are based on an
ISO 26262-compliant development flow, we do our utmost
4
to support our customers’ designs in achieving the ASIL
classification. This means that they can be deployed directly in all safety-relevant applications – making us a leader in
supporting ISO 26262-compliant systems.
Our side airbag pressure sensors, for example, detect the
spike in pressure caused by a side impact, thereby triggering the side airbag. These sensors are positioned in the
car’s door compartments and are regarded as the fastest
method of deploying life-saving side airbags. Similar devices are also used in new pedestrian protection systems.
These are designed to release a car’s hood if it is involved in
a collision with a pedestrian, thus reducing the impact for
the pedestrian.
Infineon’s 77-GHz chips are used in radar-based driver
assistance systems – such as adaptive cruise control and
collision warning – which recognize objects at a range of
up to 250 meters. With 15 million chips already shipped, we
are the market leader in radar chips. A radar-based driver
assistance system is mandatory in order to achieve the
highest rat­ing of five stars from the independent Euro NCAP
(European New Car Assessment Program) organization,
which reviews the safety of new vehicles sold in Europe.
Sensor ICs for Tire Pressure Monitoring Systems (TPMS)
help to boost car safety levels by warning drivers of any
loss in tire pressure. These important safety features also
Introduction
support energy efficiency, as a car with tires that are not
fully inflated consumes more fuel and the tires wear down
more quickly. Pressure-related downtime is a significant
cost factor for operators of commercial vehicles. We offer
TPMS sensors covering all tire pressure ranges, making us
a leading provider of these safety-critical components for
automotive system suppliers.
Wheel speed sensor ICs are faced with an ever-growing list
of requirements. Whereas years ago, ABS systems simply
needed to know when a wheel was blocked, today the increasing number of modules calls for speed sensors with an
array of intelligent functions. Indirect TPMS, for example,
uses sophisticated algorithms to determine if a wheel lacks
air pressure. Nowadays, every second car worldwide uses
our wheel speed sensors.
Modern powertrain systems rely on magnetic speed sensors, along with automotive pressure sensors, to achieve
the required CO2 targets and smart powertrain solutions.
Infineon offers a broad variety of magnetic speed sensors
for camshaft, crankshaft and transmission applications.
Our pressure sensor families for MAP and BAP applications
As the technology leader, we provide highly innovative
sensor ICs based on an excellent technology portfolio –
Hall, AMR, GMR and TMR
are especially designed to support the highest requirements
in automotive applications, such as optimized fuel consumption or car seats with an increased level of comfort.
The number of industrial and consumer applications that
rely on magnetic sensor ICs is also on the rise, further
fueling demand for our products. Our products are key
components for high-efficiency, smarter and more comfortable operation. Our Hall switches, for example, are regarded
as an ideal solution for current commutation in brushless
drives (BLDC). Many applications require conventional block
commutation – and Hall switches are the perfect fit here.
Efficiency levels can be raised even further by directly measuring the rotor angle with our angle sensor family.
Our newly launched innovative 3D magnetic sensor family,
with low current consumption and cost-optimized design,
specifically addresses the needs of new magnetic sensor
applications and is, for example, dedicated to industrial and
consumer applications such as control elements, joysticks
and E-meters (anti-tampering). Furthermore, it is the ideal
fit for low-power 3D magnetic automotive applications such
as indicators and gear shifters.
We support our customers in achieving the highest
ASIL on system level by providing ISO 26262

Applications
A typical product to system solution – magnetic sensors for highest energy
efficiency and functional safety in Electric Power Steering (EPS)
Compared to conventional hydraulic power steering solutions, Electric Power Steering (EPS) enables higher energy
efficiency, increased steering functionality and a reduced
build space in passenger vehicles.
The functionality of EPS is based on several system-side position sensors that measure the steering torque input from
the driver, the position of the EPS motor that moves the
steering rack and the steering wheel’s absolute position.

Position sensor applications in EPS are safety-related and
typically rated with the highest ASIL-D safety level. The
ISO 26262 standard sets high requirements for the diagnostic coverage of random failures and the avoidance of
systematic failures in order to reach the highest ASIL-D
safety level. These demanding specifications can typically
be achieved by using redundant sensors as well as comparing their signals on a microcontroller.
Steering torque
BLDC motor
Infineon offers dual-sensor solutions with two redundant
sensors in the place of one for all position sensor applications in EPS. Our dual-sensor package integrates two
magnetic position sensors with a separate power supply
and separate signal outputs. They are electrically independent thanks to galvanic isolation. This means that the two
sensors work independently, thereby increasing system
reliability.

Thanks to the use of innovative stack-mounting technology, the devices of the angle sensor family combine two independent sensors within standard and space-saving TDSO
packages which are only about 1 mm thick. It has the same
width and length as a conventional single-sensor package.
Compared to the common approach of side-by-side sensor
placement, the advantages of the top-bottom placement
include a more homogeneous magnetic field over the
sensing elements and a significantly smaller footprint. This
saves precious space and cuts down on expense in safety-critical applications, as a lower-cost ferrite magnet can
provide a sufficient magnetic field for the sensors.
Steering torque sensors
In the field of steering torque sensing, Infineon’s TLE499x
series offers highly accurate linear Hall sensors for magnetic torque sensing assembly. In order to support a maximum
of compatibility with various Electronic Control Unit (ECU)
10
designs, the TLE499x sensors feature PWM, SENT, SPC or
ratiometric analog output. They are available in leaded
packages as well as 1 mm-thick dual- or single-sensor SMD
packages.

output. Available in a 3- or 4-pin leaded package (with or without integrated capacitors) and an

Conventional EPS systems using two linear Hall sensors for
ASIL-D compliance have to shut-down in the event of a loss
of one sensor signal. Therefore, the trend in EPS systems
is to increase availability by implementing additional
sensor signals or plausibility mechanisms. To support this
trend towards high-availabilty EPS functionality, Infineon
recommends the usage of two TLE4998 dual-sensors. In
case of one TLE4998 signal loss, the remaining dual-sensor
in the system provides continued operation of the EPS,
avoiding an immediate system shut-down.

Steering angle sensors
The absolute steering angle position is an input for the
Electronic Stability Program (ESP) and other driver
assistance systems. A typical module design used for
steering angle measurement is a design featuring gear
wheels with a slightly different number of gears. The angular positions of the gear wheels are measured by two angle
sensors, where the absolute steering wheel position is
calculated from those positions via the Vernier principle.

The angle sensors for absolute steering angle measure­
ment are available as a single-sensor SMD package for
conventional designs, which achieve the ASIL-D rating
via a plausibility calculation of the two angle sensor signals
as a result of a significant movement of the steering wheel.
The sensors are also available in dual-sensor packages
for module designs that support an ASIL-D-rated steering
angle directly at power-on (ASIL-D from start).

Infineon angle sensors support steering angle sensor configurations with an on-board microcontroller, as well as satellite sensor designs, due to a broad variety of supported
communication interfaces. In particular, the SPC interface
allows the connection of angle sensor(s) and linear Hall
sensor(s) on a bus line in combined Torque-Angle-Sensor
(TAS) modules. Compared to conventional designs with
separate torque sensor and angle sensor modules, this
configuration reduces the cost of wiring and saves module
space.

Applications
EPS motor position sensors
The motor that drives the steering rack in an EPS system
is usually a highly efficient brushless DC (BLDC) motor
which relies on a fast and accurate position sensor for
commutation. In this application, short latency and high
accuracy are essential, as these sensor parameters have
a significant impact on torque stability and the energy
efficiency of the motor.

Sensor
As correct commutation of the EPS motor has to be ensured in order to avoid blocked steering or erratic steering
support, this application is also rated ASIL-D. To achieve
this high level of functional safety, Infineon offers angle
sensors in the dual-sensor package that allow the integration of two redundant sensors in the place of one.
The TLE5309D, in particular, meets the highest functional
safety requirements by using a combination of AMR
(Anisotropic-Magneto-Resistance) and GMR (Giant-Magneto-Resistance) technology, which not just offers redundancy, but also integrated diversity in a single product.
Depending on the overall EPS system architecture, the motor position sensor can be directly mounted on the steering
ECU, or connected via a cable in a satellite configuration.
The very high level of sensor accuracy required for highest
energy efficiency, comparable to the performance of costly
resolver solutions, is typically achieved by implementing a
continuous calibration algorithm on the steering ECU. By
monitoring the sensors output signals and calculating the
compensation parameters during operation, this algorithm
compensates any drift errors that occur over temperature
and lifetime.

Dual-sensor package
Two sensors in one SMD package
The new SMD package (TDSO) includes two independent
sensors with separate power supply and separate signal
outputs. Due to special mounting technology, Infineon is
able to keep dual-sensor package size very small to enable
compact PCB layouts and small magnet sizes.
Infineon offers linear Hall sensors or angle sensors in the
TDSO package. The two sensors in one package offer
sensor redundancy in one package. Sensor redundancy
is especially interesting for new generation EPS steering
systems with increased ISO 26262 requirements and other
safety critical applications. All sensors are automotive
qualified.
Most products are also available as single-sensor solution
with only one sensor.

Angle sensors
Angle sensors
We offer a family of angle sensors based on integrated Magneto Resistive (ixMR)
technologies. The sensors detect the orientation of an applied magnetic field
by measuring sine and cosine angle components with monolithically integrated
magneto resistive elements. ixMR technology is now widely used in automotive
and industrial applications and provides a wide range of benefits.
Low sensitivity to air gap variations: The ixMR element senses a field’s direction,
not its intensity. Variations in field intensity within the sensor’s range therefore
have a minimal impact on angle accuracy.
Improved tolerance to misalignment: The area sensitive to ixMR is very small. It
is therefore easier to keep it within the homogeneous zone of the magnetic field,
in case of a small mechanical failure.
High speed: ixMR technology is extremely fast. Its speed is not limited by the
reaction time of the MR element but by delays in the amplifier circuit.
High degree of integration: The data processing and communication interfaces are integrated in the same silicon chip as the sensing elements. This enables compact designs using small outline packages. The angle sensors
are available with a wide variety of communication interfaces as well as different levels of data processing and
self-testing capabilities, making them ideal for safety-relevant applications in the automotive sector.

Magnetic speed sensors
Magnetic speed sensors
Our Hall- and GMR-based magnetic speed sensors are designed to measure speed in safety and powertrain applications such as speedometers, ABS, camshafts/crankshafts
and automatic transmissions. They are also used in similar
applications in the industrial sector. The sensors use a
ferromagnetic gear tooth or encoder structure to measure
linear or rotational speed and position. Hall sensor measuring rotational speed with a gear tooth and a magnetic
encoder wheel.
We offer a broad range of options to ensure the perfect fit
for individual customer applications, including voltage and
current interfaces with optional current detection or vibration suppression. By integrating the magnetic Hall or GMR
sensing cell and the signal processing unit on a single chip,
we deliver optimum performance and cost savings.
The majority of sensors also feature additional benefits
such as integrated capacitors (C- types) for high EMC
robustness and the highest levels of ESD protection. Our
sensors also come in a range of innovative package designs
with integrated back-bias magnets (iBB package).
We have an outstanding record of excellence in the automotive sector. Over two billion of our integrated magnetic
sensors are installed in cars all over the world, delivering
extremely reliable results in safety-relevant applications
such as ABS, and in extremely harsh environments such as
engines and transmissions.

Magnetic speed sensors
Safety first: Infineon Wheel Speed Sensors
Nowadays, wheel speed sensors are confronted with an
ever-growing list of questions and requirements. Years
ago, ABS systems simply needed to know if a wheel was
blocked, and then ESC used the accurate speed of all four
wheels for its corrections. Since then, an increasing number
of modules in the car take the wheel speed into account
for their intelligent functions. The electrical parking brake,
for example, needs to know about every inch a car moves
when it’s supposed to be stationary, and iTPMS uses sophisticated algorithms to determine if a wheel lacks air
pressure, and even the central locking locks the doors after
a couple of meters and the radio turns up the volume in
line with increasing speed. All of the above rely on accurate
information from the wheel speed sensor.
Currently, one out of every two cars worldwide uses our
wheel speed sensors for these vital, safety-relevant tasks –
over 1 billion Infineon wheel speed sensors have been sold
over the past decade and contributed every day to make
people’s lives safer.
Features
››High sensitivity for large air gap applications
››Differential principle against stray fields and other
disturbances
››Single-chip solution for outstanding reliability
››Best-in-class slim package sets a global benchmark for
the smallest-possible size of the sensor module
››High resistance against temperature change:
No unwanted pulses at thermal drift
››Integrated 1.8 nF over-molded capacitor enhances
EMC and micro-break resistance without the need for
external components
Applications
››Wheel speed sensing in automotive applications
››Antilock Braking Systems (ABS)
››Electronic Stability Programs (ESP)
››Automatic transmissions

TLE4983/84C
Outstanding camshaft sensing
Our TLE4983/84 chopped mono-Hall sensor family comprises an excellent dedicated feature set. It is highly robust
and comes with a module-style package with integrated
capacitors. All of which makes it the perfect fit for automo­
tive camshaft applications. The product family meets all
key camshaft sensor requirements including true power-on,
Twist-Independent Mounting (TIM) and high phase
accuracy for optimum fuel-injection timing. Both sensors
deploy a dynamic self-calibration algorithm with prog­
rammable power-on and a dynamic switching point.
TLE4984, for example, uses an algorithm that enables fast
threshold adjustments with small step sizes during the
pre-calibration phase. This, in turn, allows thresholds to be
adjusted very accurately. In contrast, the step sizes used
by TLE4983 in the pre-calibration phase are approximately
10 times larger. TLE4983 therefore requires only half of
the switching events used by TLE4984 to reach calibration
mode. These flexible options give designers the freedom
to choose the best start-up concept for individual system
requirements.

Current sensor
TLI/TLE4970
High-precision current sensor
TLI4970 is a high-precision current sensor for industrial applications based on our proven Hall technology. The coreless concept significantly reduces footprint compared with
existing solutions. TLI4970 is an easy-to-use, fully digital
solution that does not require external calibration or additional parts such as A/D converters, 0 pAmps or reference
voltage. It thus significantly reduces overall implementation effort as well as PCB space and cost.
The differential measurement principle integrated in the
TLI4970 sensor suppresses interference caused by external
magnetic fields. Accordingly, the sensor achieves an extremely low offset of just 25 mA. With conventional current
measurement principles, the measuring accuracy is always
governed by the ambient conditions (e.g. the temperature).
TLI4970 is more accurate than existing open-loop and comparable to closed-loop systems. It also provides additional
functions such as fast overcurrent detection and programmable filters yet has a significantly smaller footprint and
lower power consumption.
TLI4970 is extremely robust against external magnetic
fields thanks to implemented stray field suppression and
is also suitable for fast overcurrent detection at a pre-configurable level. This allows the control unit to switch off
independently of the main measurement path and protect
power consumers from damage.

Integrated pressure sensor ICs
For industrial and automotive applications
Our integrated pressure sensor family uses unique multiple
surface micro-machined capacitive sensor cell arrays
that support powerful self-diagnosis features such as mechanical and electrical verification of sensor functionality.
Monolithic integration onto a single chip enables stateof-the-art production using a standard automotive-qualified BiCMOS process. Sophisticated sensor cell design
combined with fully digital signal conditioning and processing based on high-volume production flows ensures supe­
rior quality over the entire lifecycle.
These pressure sensors are ideal for a wide range of applications in the automotive and industrial sectors.
The analog and digital interfaces of our pressure sensors
provide customers with a high degree of design flexi­
bility and enable manufacturers to meet evolving market
demands.
Our digital interface portfolio ranges from PSI5 for safety
products (for example side crash detection and pedestrian
protection systems) through SPI for automotive powertrain and body applications (for example Barometric Air
Pressure (BAP), fuel vapor and seat comfort systems) to
SENT with SPC functionality for upcoming engine management products (for example MAP, turbo MAP (with NTC) and
secondary air valves).
Current automotive restraint systems use Infineon’s side airbag pressure sensors to fulfill the
steadily increasing safety requirements for passenger cars. In this safety-critical application, the
pressure sensor is assembled within the car’s side doors and provides – within fractions of
a second – a digital crash signal to the central airbag unit. Self-diagnosis routines reliable proper
operation every time.
As the safety standards for passenger vehicles increases beyond the side airbag for inmates to
secure the safety of pedestrians, Infineon’s new sensors (KP200 and KP201 for higher operating
temperature) allow our customers to get the highest 5 stars evaluation for vehicle safety.

Integrated pressure
sensor ICs
SP27
Pressure sensor for industrial and automotive applications
The SP27 is a pressure sensor designed for the harshest
automotive and industrial environments. Among its unique
selling points, the device offers a wide pressure range up to
1300 kPa and a proven sensor technology which is robust
against various media.
It can be used in both wired and battery-supplied applications.
The SP27 is a complete system on package since it integrates a microcontroller with 6 kB flash and several peripherals (such as temperature and voltage sensors on top of
the pressure sensor); it requires very few external components.
Its data interface is I2C; but nevertheless, the integrated
µc allows the implementation of specific communication
protocols such as SPI, SPC, SENT or PWM. The integrated
microcontroller is instruction-set compatible with a standard 8051 processor. Integrated on-chip flash memory
can be used to store a customer-specific application code,
along with its unique ID number and the calibration data
for the sensors. Additional on-chip ROM memory is available and includes functions (developed by Infineon) that
cover standard tasks used by the application.
The device can be programmed to wake-up at regular
intervals via its low-power interval-timer or per an external
wake-up source connected to a General Purpose Input/
Output (GPIO), thus allowing the application to save energy
by spending most of the time in SLEEP mode.

Functional safety
Functional safety – ISO 26262
ISO 26262 defines the development of electric and
electronic automotive systems with regard to their functional safety. The aim of this standard is to reduce possible
hazards caused by the failure and malfunction of such
systems. The safety requirements for the development
process depend on the ASIL rating of the target application
and can range from ASIL-A to ASIL-D. Applications such
as steering or braking systems are rated with the highest
ASIL-D level. A failure in such a system can lead to an out-ofcontol vehicle, possibly resulting in fatal injuries.
All newly developed parts will be based on an
ISO 26262-compliant development flow, thereby allowing
direct use in all safety-relevant applications. Devices which
are developed prior to the ISO 26262 as a QM part can nevertheless be used in ISO-compliant systems as outlined
in part 8 clause 13 of the standard. In such cases, it is mandatory “to provide evidence of the suitability of ... hardware
components and parts” for use in ISO-compliant systems
and also to provide failure modes, their distribution and
diagnostic capability.
To support our customers as they strive to achieve the
highest ASIL on system level, Infineon provides both
the necessary support for qualification of existing pre-
ISO 26262 products, and fully ISO 26262-compliant
products of the future.
For a set of existing Infineon sensor ICs, extensive functio­
nal safety analyses have been conducted for various
application use cases by means of FMEDA (Failure Mode,
Effects and Diagnostic Analysis), DFA (Dependent Failure
Analysis) and also FTA (Fault-Tree Analysis) to make them
“ASIL-ready”. The resulting FIT rates and safety-related
judgements of these analyses are summarized in Safety
Analysis Summary Reports. These reports are available
to customers for interfacing with their system-level safety
concept. The preferred implementation of the “ASIL-ready”
sensor ICs is described in dedicated safety manuals.
Additionally, Infineon offers expert support for system integrators in achieving the required ASIL on system level.
Future Infineon sensor IC developments for safety-related
applications will follow the full ISO 26262-compliant process: A V-model based requirements capturing and verification process ensures the fulfillment of ASIL-rated safety
requirements. Furthermore, dedicated safety analyses are
already performed during development to support the
achievement of the required safety targets. The resulting
sensor IC can therefore be easily used in safety-related
applications.
Infineon PRO-SIL™
The functional complexity and levels of integration of
real-time, safety-critical applications continue to increase.
Norms such as IEC 61508 and ISO 26262 mandate more robust products and functional safety concepts in automotive
and industrial applications.
Infineon’s PRO-SIL™ trademark designates Infineon
products which contain SIL-supporting (Safety Integrity
Level) features. The SIL-supporting features are intended to
assist the overall system design in attaining the desired SIL
(according to IEC 61508) or A-SIL (according to ISO 26262)
level for safety systems with high efficiency. Products with
the PRO-SIL™ label will help you to select Infineon products
for safety-relevant (automotive) systems.
