About

Seamless integration and highest-possible safety standards

We recognize that braking and steering are two of the most important safety functions of a vehicle, and we translate that into a system-level approach to functional safety with products that are ISO 26262 compliant and developed together to meet the strictest standards in safety and robustness.

With a proven track record and years of experience in the automotive sector, Infineon is the right partner for any electric power steering project. Our components have been designed and tested to ensure they work seamlessly and fulfill the highest-possible safety standards. Since our chipset is aligned in-house, you can count on its interoperability to ensure safety while reducing your development effort. Thanks to a small footprint and integrated features, our solution contributes to a lower BOM.

Furthermore, our chipset is suitable for OEMs who want to scale platform solutions across models to increase cost efficiency, from fail-safe to fully redundant fail-operational and high-availability solutions. Last but not least, there’s the peace of mind you gain knowing that all components are manufactured according to Infineon’s high automotive quality standards.

Reliable sensors, regulators, microcontrollers, drivers, and MOSFETs

We have over two decades of expertise in chassis application solutions, deep know-how of safe motor control, dependable products, technical documents, and evaluation boards. With that, we cover every major socket in chassis actuators to enable easy design-in and fast time to market:

  • Powerful and scalable chipset featuring a small footprint
  • Field-proven interoperability
  • Support of fail-safe and fail-operational EPS systems
  • Harmonized safety concept that focuses on the power supply and microcontrollers
  • Adaptability via software: suits a range of driving modes and car models
  • Designed for a wide range of applications, from advanced driver assistance systems (ADAS) to actuators

For all your development needs, Infineon provides the full range of ICs, from safety microcontrollers to power supplies, bridge drivers, world-class MOSFETs, and sensors. Find out what is possible with our components to enhance your EPS project.
