Infineon Sensors – Making Lives Easier,
Safer and More Comfortable
At Infineon, we strive for in making lives easier, safer and
more comfortable by application of sensor technologies.
Leveraging our full innovation potential, our sensor ICs
are at the heart of a wide range of sensing applications.
They transform physical readings such as barometric air
pressure, car tire pressure or various magnetic fields into
electronic signals, which can then be processed further.
To do this, the sensor ICs have to be in direct contact
with the outside world, often functioning as standalone
satellites that are not part of a protected circuit board.
This means that they are exposed to significantly
harsher mechanical, chemical and electrical forces than
conventional semiconductor devices. The ability to
withstand these environments calls for special packaging
technologies, dedicated silicon processes and robust
sensing elements – making sensor ICs complex and
challenging devices to manufacture.
The company has sold more than three billion integrated
magnetic and pressure sensors over the past 10 years.
Infineon is number one in wheel speed and pressure
sensors for both side airbags and tire pressure monitoring
systems. With regard to Electric Power Steering (EPS),
Infineon once again leads the way with a market share of
about one third. As a strong partner, the company supplies
the automotive market with more than one million
sensors per day.

Today, a new car features up to 80 applications that rely
on magnetic sensors. And this number is growing. We have
kept pace with this development by diversifying our product
offering. Whereas ten years ago, one type of speed sensor
would have covered most speed sensing applications, we now
have dedicated product lines for wheel speed, transmission
speed, crankshaft and camshaft sensing. Our magnetic sensor
portfolio now comprises over 250 different products.
At Infineon, we are committed to making cars safer. Our
side airbag pressure sensors, for example, detect the spike
in pressure caused by a side impact and trigger the side
airbag. These sensors are located in the door compartments
of a car 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 lessening the impact for the pedestrian.
The sensors are located in a tube in the car’s bumper and
trigger the hood if they detect a spike in pressure.
example, come in high-volume eWLB packages and are the
ideal building blocks for cost-efficient radar systems used
in Automotive Cruise Control (ACC), Blind-Spot Detection
(BSD) and Auto-Emergency-Braking (AEB) applications. They
also address upcoming Euro NCAP requirements for active
passenger and pedestrian safety features.
Barometric air pressure sensors, for example, apply different
pressure levels to various segments in a car seat to increase
comfort levels. Wheel speed sensor ICs are also used to
measure the speed of each wheel and detect whether a
wheel blocks during breaking (ABS). This measurement is
also the basic input signals for a car’s Electronic Stability
Program (ESP). ESP makes it easier – and therefore safer –
for drivers to handle a car in critical situations. Magnetic
angle sensors and linear Hall sensors are also used to
measure steering angle and steering torque.
Watch now – Leading Infineon Sensors for Industrial
Applications
Our sensors for Tire Pressure Monitoring System (TPMS)
also help to raise car safety levels by warning drivers of any
loss in tire pressure. These important safety features are
also good for energy efficiency – 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 many operators of commercial vehicles, for
instance. We have already shipped over 150 million TPMS
sensors covering all tire pressure ranges, making us the
leading provider of these safety-critical components for
automotive system suppliers.
Ease of use is another factor that impacts driver comfort and
safety. Our SiGe-based 77-GHz RF transmitters/receivers, for

The number of industrial and consumer applications that
rely on magnetic and pressure sensor ICs is also on the
rise, further fuelling demand for our products. Our Hall
switches, for example, comprise Infineon’s latest easyto-use and cost-effective Hall sensor family for consumer
applications, as well as magnetic angle sensors. Hall
switches are also 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 further by directly measuring the rotor angle. This
saves energy and eliminates vibrations, which in turn cuts
noise levels and ensures smoother integration. The same
angle sensor products are used in e-bikes, paving the way
for more comfortable and energy-saving mobility concepts.
Nowadays, cars are fitted with an average
of 20 magnetic and low pressure sensors.
Four of these are provided by Infineon.
Our latest 3D magnetic sensor family with low current
consumption is dedicated for industrial and consumer
applications such tampering detection in e-meter and
flow meter.
Providing sensor ICs for all of the examples above requires
a very broad mix of technologies. As a technology leader,
we use Hall and magnetoresistive sensing elements (GMR
and AMR) for our monolithically integrated magnetic
sensors. Our pressure sensors are built on surface and bulk
micro machined MEMS technologies. Our extensive offering
and exacting quality standards reflect our commitment
to making lives easier, safer and more comfortable. We are
often regarded as the industry benchmark.
Infineon is the only provider
offering integrated sensor ICs based
on Hall, iAMR and iGMR.

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.
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 PG-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 safetycritical 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)
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.

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 measurement 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 dualsensor 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.

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.

Highly Robust, Easy-to-Use Mono-Hall Speed Sensor with
Twist-Independent Mounting
This sensor is specially designed to provide an easy-to-use,
robust and cost-effective solution for vehicle or industrial
speed sensing applications. The TLE4922 can therefore be
back-biased using a simple, low-cost bulk magnet, while

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.

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 automotive 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
programmable 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
TLI4970
High-Precision Current Sensor
TLI4970 is a high-precision current sensor 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.
Features
„„
Fully calibrated digital output
„„
High accuracy over life time due to on-chip temperature
and stress compensation
„„
Programmable low-pass filter
for measuring current (0–18 kHz)
„„
Fast, configurable overcurrent detector (< 1.8 ps typ.)
„„
Inherent magnetic stray field suppression
„„
Small package size and weight for SMD mounting
TLI4970 is extremely robust against external magnetic
fields thanks to implemented stray field suppression and
is also suitable for fast overcurrent detection at a preconfigurable 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 state-of-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 superior 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 flexibility
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.

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.

Tire Pressure Sensor
SP37
Tire Pressure Sensor for Tire Pressure Monitoring Systems (TPMS)
SP37 is a highly integrated device that performs all
functions required for a Tire Pressure Monitoring
System (TPMS) wheel module. It is ideal for highvolume applications, bundling the sensing elements,
microcontroller, LF receiver, RF transmitter and other
components in a single package. Only very few external
components are required to create a TPMS module.
SP37 measures pressure, radial acceleration, temperature
and supply voltage and is certified as a green package
compliant with RoHS. SP37 comes in a number of variants
with different pressure ranges (100 to 450 kPa, 100 to
900 kPa and 100 to 1300 kPa), making it the ideal choice for
light vehicle and heavy truck applications.

RASIC™
RASIC™
Front-End ICs for Automotive RADARs
Since volume production started in 2009, RASIC™ chips have become the
market leader in the 77 GHz SiGe MMIC segment. They can be used in different
configurations to build RF front-end modules for sensors in applications such
as Long-Range RADARs (LRR) (for example ACC), Lane Change Assist (LCA)
and Blind Spot Detection (BSD) systems as well as in Collision Mitigation (CM)
and Emergency Brake Assist (EBA) features. All components are AEC-Q100
qualified and specified over the full -40 … +125 °C automotive temperature
range.
RTN7735PL Transmitter and RRN7745PL Receiver in eWLB
RTN7735PL and RRN7745P are the first 77 GHz solutions based on an eWLB
package instead of a bare-die. They form a scalable platform comprising a
three-channel transmitter and a four-channel receiver to build long- and midrange systems.
RPN7720PL Power Amplifier in eWLB
The RPN7720PL dual-power amplifier allows to increase system output power
plus additional output switching and phase shifting of two Tx channels.
RCC1010 RADAR Companion Chip in PG-TQFP-48 PGN
The RCC1010 radar companion is a CMOS chip which provides a fully digital
interface to RTN7730 and RTN7735P. It features freely programmable
modulation waveform generation and PLL frequency control.

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-of-contol
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
functional 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’s PRO-SIL™ Program,
Designed to Protect
The functional complexity and levels of integration of realtime safety-critical applications continue to increase.
Norms such as IEC 61509 and ISO 26262 mandate more
robust and comprehensive product development processes
and functional safety concepts in automotive and industrial
applications.
Infineon’s PRO-SIL™ safety program is designed to ease and
speed up your automotive and industrial design to
comply with such standards. Across the full certification
spectrum from Safety Integrity Levels (SIL) 1 to 4 and
Automotive Safety Integrity Levels (ASIL) A to D, our endto-end PRO-SIL™ approach will help you select the right
hardware, software and functional safety concepts to meet
your design and compliance needs.
