Electric Power Steering System

Overview

Electric power steering (EPS) is a crucial automotive application that demands the highest level of functional safety - Automotive Safety Integrity Level D (ASIL-D). This comprehensive system meets these stringent safety standards through a combination of an MCU and a power management IC (PMIC), both specifically optimized for ASIL-D systems.

System Benefits:

  • The high-end automotive MCU features a variety of integrated safety elements designed for chassis systems meeting ASIL-D requirements.
  • The PMIC, designed for this MCU, offers extensive fault diagnosis and monitoring functions, supporting ASIL-D systems while reducing system bill-of-material costs and conserving PCB space.
  • The proven combination of MCU and PMIC reduces R&D costs and time, enabling a faster time-to-market.
