Electric Power Steering (EPS)

Electric power steering (EPS) systems make steering easier by providing additional torque by brushless DC motors. Steer-by-wire and related safety requirements are driving the introduction of dual-redundancy systems. The motor power can be increased depending on the installation point, starting from the steering column, pinion to the steering rack. The higher the motor power, the higher the capability of autonomous driving, with the final leap towards complete vehicle autonomy necessitating complete mechanical disconnection in Steer-by-wire systems.

Design considerations

  • Input protection from reverse battery connection is achieved by ideal diode controllers
  • Dual-redundancy designs require greater power densities and space saving, enabled by LFPAK56/56E package
  • Safe and reliable switching of the MOSFETs is provided by integrated gate drivers
  • Integrated converters provide turn-key solution for voltage conversion
  • Efficient and smooth switching can be achieved with Schottky diodes in trench technology
  • Further space saving, better thermal performance and automatic optical inspection are some of the advantages of small signal discrete and logic components in new DFN and CFP packages
  • Signal voltage level differences between design sections can  adjusted by bidirectional (NXB family for signal edge acceleration) and unidirectional (NXU family for signal integrity improvement) translators
