Electric Power Steering (EPS)
Last Updated: Nov 12, 2021
Electric Power Steering (EPS) offers improved handling and steering feel while improving
vehicle safety by adopting the steering torque to the vehicle speed and providing active torque
in critical driving situations. Our 16-bit and 32-bit single and dual-core automotive MCUs
provide enhanced computing power and specialized peripherals for complex electric motor
control functions. Integrated power supply solutions are also important elements of a power
steering control unit. They provide connectivity to automotive busses, such as CAN and LIN.
For MOSFET power stages control, integrated pre-drivers are typically used to interface with the
MCU directly or via SPI.
