Focus MOSFET application – Engine management

Application Considerations

Injector/valve controllers form a building block within both diesel and gasoline engine control modules to deliver optimum fuel consumption. The injectors are controlled by a complex ‘peak and hold’ current control. The “peak” current opens the valve and the “hold” current maintains the valve in the open position.

Diesel Injection: Various topologies are used, but are usually differentiated by those that apply a boost voltage and those that don’t.

Gasoline Injection: The main configurations are 'multi-point' and 'direct' injection. The circuit topology is similar to that of diesel injectors.

Key MOSFET Requirements:

  • High lifetime reliability
  • High current transient robustness
  • Good thermal performance
  • Small footprint
  • Guaranteed repetitive avalanche capability
