Safety applications
Both customer demands and government legislation continue to improve traffic safety. Electric and electronic safety systems play a key role in this trend. Electric power steering is a good example of how a safety application perfectly combines improved fuel efficiency with enhanced comfort.
Infineon is the broadest supplier with a portfolio extending from intelligent sensors and microcontrollers through automotive power standard products and Application-Specific Standard Products (ASSPs) to highly integrated customized Application-Specific ICs (ASICs). This comprehensive product portfolio – com- bined with our application expertise gained during four decades of activity in the automotive industry – positions us ideally to help customers overcome their key challenges. These include ongoing application optimization plus the implementa- tion of new features to meet stringent safety requirements. The ISO 26262 safety standard is one example of the exacting standards that apply today.
To help customers to reach the desired Automotive Safety Integrity Level (ASIL) certification, Infineon has already introduced its own PRO-SIL™ concept. This trademark clearly identifies the products which contain “SIL-supporting” fea- tures. The Infineon PRO-SIL™ concept includes safety-focused organization and business processes for the generation of hardware and software safety features, including safety documentation.
The functional complexity and levels of integration of real-time safety-critical applications continue to increase exponentially. In addition, the product life cycle of these applications has to meet stringent safety standards. The ISO 26262 mandates more robust and comprehensive product development processes and functional safety concepts in automotive applications.

Body applications
Body and convenience applications
Infineon offers a wide variety of products dedicated to body and interior elec- tronics. These include protected power switches for bulb and motor control, dedicated system basis chips and easy-to-use Hall sensor solutions. The new TriCore™-based AURIX™ family provides sufficient performance, as well as dedicated safety and security features, to meet the needs of upcoming domain electronics modules. As one example, a high-feature body control module with integrated gateway functionality is shown on page 27.
The following pages present well-known electronic modules for car body interior and comfort systems, such as the body control modules including a dedicated low-cost version, the Seat Electronics Module and the HVAC control module. Further modules reveal the growing trend toward decentralized modules at the point of load, such as a front light module or a smart window lift module.
Some new electronic module designs reflect the latest functional and archi tectural advances. One prominent example is a power distribution system for high-current applications supporting the move toward more advanced and efficient wiring harness systems in start/stop-capable vehicles. Another exam ple is an interior light module with touch-sensitive control based on a similar human-machine interface to that featured in the latest consumer electronics devices. Finally, the growing family of system-on-chip devices supports space and cost-optimized single-chip solutions for various motor control applications, such as window lift, fuel pump and HVAC blower.

Powertrain applications
Powertrain applications
The powertrain market is driven by the need to reduce the carbon footprint of cars via affordable, efficiency-enhancing innovations. Concrete measures include rightsizing engines, improving fuel injection accuracy and increasing after-treat- ment efficiency. On the transmission side, car-makers are looking to optimize both the gear ratio and gear shifting. Other efficiency-enabling activities include reducing friction and hydraulic losses. In a more general context, the drive for greater ecology on the roads is pushing the transition toward vehicle electrifica- tion and hybridization.
As one of the largest automotive semiconductor suppliers, Infineon has been active in the powertrain electronic business for over 40 years. Our position as innovation leader, coupled with longterm partnerships with OEMs, Tier 1 and engineering service providers, means we reap the benefits of in-depth system expertise and broad application competence. Infineon delivers an extensive range of optimized, competitive and scalable powertrain products and chipset solutions. Our portfolio covers the full sensor spectrum from position, over angle and speed to barometric and manifold pressure, supplemented by a strong 8-bit, 16-bit and 32-bit powertrain microcontroller portfolio. In addition to the neces- sary power components, such as voltage supplies, MOSFETs and IGBTs, smart low-side and high-side switches, CAN/LIN and FlexRay transceivers, the product range is rounded off by a multitude of highly integrated automotive system ICs, such as engine management ICs, alternator regulators, System Basis Chips (SBC) and constant current control ICs for transmission control.
Electrification is the key topic in the powertrain segment. 48 V mild-hybrid, hybrid and battery electric vehicles will penetrate the market over the coming years and will see double digit growth rates. Infineon doesn’t only have more than 70 years of experience in power semiconductors & packaging, but has started years ago to significantly invest into enlarging the portfolio to serve automotive needs. Today, Infineon provides the largest portfolio of product and chipset solutions in the market for all new applications like traction and auxiliary inverters, onboard char- gers, power converters (DC-DC) and battery management systems. The products’ range covers high-performant microcontrollers, networking ICs, ASICs, sensors, drivers, low- and high-voltage power components. All of them are specifically designed for automotive use and are developed based on our long experience in the automotive environment.
