FEATURES
:● Operates over supply voltage range of 4.5 V < VPWR < 36 V
● Start-up/shutdown control and power sequence logic with KEYSW input
● MCU supply: VCC is a 5.0 V (±2.0 %, 200 mA) regulated supply
● Sensor supply: VPROT (100 mA) is a VCC tracking protected sensor supply
● Three configurable pre-drivers for IGBT or general purpose gate MOSFETs for ignition and O2 sensor (HEGO) heater:
● 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
