  • MCU supply: VCC is a 5.0V (±2.0%, 200 mA) regulated supply
  • Sensor supply: VPROT (100 mA) is a VCC tracking protected sensor supply
  • Two configurable pre-drivers for IGBT or general purpose gate MOSFETs for
  • ignition and O2 sensor (HEGO) heater:
    • PWM
    • Overcurrent shutdown
    • Short-to-battery shutdown
  • PWM
  • Overcurrent shutdown
  • Short-to-battery shutdown
  • Six low-side drivers with full diagnostics, self-protection and PWM control:
    • Two fuel injector drivers, RDS(on) = 0.6 Ω, ILIMIT = 1.8 A, to drive typical 12 Ω
    • high-impedance injectors
