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 products and documentation Infineon integrated magnetic and pressure sensors.

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. Typical application for Infineon magnetic position sensors in EPS Steering torque sensing Steering angle sensing TLE499x – linear Hall sensor series TLE5014/TLE5012B – angle sensor TLE5009 – angle sensor EPS motor position sensing TLE5x09D – dual-sensor angle TLE5012BD – dual-sensor angle Linear Hall Angle sensors 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. 9 Applications A typical product to system solution – magnetic sensors for the ultimate in energy efficiency and functional safety in Electric Power Steering (EPS) Side view of Innovative stack-mounted dual-sensor technology with bonding wires Sensing element Transparent 3D-graph of dual-sensor TDSO-16-2 package Top die Leadframe Insulating glue Spacing < 600 µm Bottom die 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. TLE4997x Programmable linear Hall sensor with temperature compensation and ratiometric analog output. Available in a 3- or 4-pin leaded package (with or without integrated capacitors) and an 8-pin dual- or single-sensor SMD package. TLE4998x Programmable linear Hall sensor with digital stress and temperature compensation and PWM, SENT or Short-PWM-Code (SPC) output. Available in a 3- or 4-pin leaded package (with or without integrated capacitors) and an 8-pin dual- or single-sensor SMD package. Applications Magnetic torque sensing assembly Input shaft Output shaft Torsion bar Stator Flux concentrator Multipole magnetic ring Sensor (e.g. TLE4998) Stator 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. Application trend: high-availabiliy Application trend: fault-tolerant EPS New OEM safety goal: avoid sudden loss of steering support, ASIL-B Limp-aside Shut-down Fault-tolerant ECU ECU Dual sensor + ECU Software, plausibility Dual sensor Failure reaction Failure reaction Failure reaction Shut-down (= sudden loss!) Limp-aside, degraded operation for very limited time Continued operation 11 Applications 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. Schematic steering angle sensor module and illustration of the vernier principle 360 Sensor 1 Sensor 2 Sensor angle 1 and 2 [°] 315 270 225 180 135 90 45 0 0 1 2 3 4 5 Steering wheel turns 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). TLE5009(D) Fast Giant-Magneto Resistive (GMR) angle sensor with analog sin/cos output. Available in a 16-pin single- and dual-sensor SMD package. TLE5012B(D) Digital GMR angle sensor with SPI + PWM or SPC output. Available in a 16-pin single- and dual-sensor SMD package. TLE5014(D) ISO 26262-compliant, programmable GMR angle sensor with PWM, SENT or SPC output. Supports Torque-Angle-Sensor (TAS) module bus configuration with TLE4998C. Will be available in a 16-pin single- and dual-sensor SMD package. 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. Schematic TAS module set-up and SPC bus configuration of the TLE5014 and TLE4998C GND 1 MPS ECU α via CAN TLE5014 TLE4998C VDD 1 BUS 1 BUS 2 VDD 2 TLE5014 TAS 12 TLE4998C GND 2 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. Schematic of BLDC motor with a magnetic position sensor for commutation EC-Motor Magnet Motor control unit 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.

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. www.infineon.com/angle-sensors 27 Angle sensors iGMR sensors Our iGMR sensors are ideal for applications with a wide angle range, for example BLDC motor or steering sensors.

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.

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.

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.

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.
