Electric Power Steering System

Electric power steering is one of the applications that requires ASIL-D*, which must be supported on a system level. Renesas provides the required power management IC (PMIC) and the RH850/P1x microcontroller (MCU) as part of this reference design.

*ASIL: Automotive Safety Integrity Level. ASIL-D is the highest Automotive Safety Integrity Level.

System Benefits:

• The high-end RH850 automotive MCU for chassis applications provides a variety of integrated safety features
• The RAA270005 PMIC is designed for the RH850/P1x MCU with various fault diagnoses and monitor functions to support ASIL-D systems to reduce system bill-of-material costs and save on PCB space
• This proven combination of MCU and PMICs shortens R&D cost and time
