Focus MOSFET application – Integrated starter generator

MOSFETs for highly reliable Brushless DC motors

Application Considerations

Integrated starter generator systems provide start-stop functionality and torque boost capability to reduce the emissions of modern vehicles.

In “alternator mode” the system acts as a regenerative brake. Whilst in “motor mode” it is used to start the engine and provide torque assistance.

MOSFETs are used to drive highly reliable Brushless DC motors.

Key MOSFET Requirements:

  • Ultra low on-resistance
  • Low thermal resistance
  • Safe high temperature operation
  • Excellent current handling
  • Guaranteed repetitive avalanche capability
