特性
  • Operates over supply voltage range of 4.5V < VPWR < 36V
  • Start-up/shut-down control and power sequence logic with KEYSW input
  • 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
  • Five low-side drivers with full diagnostics, self-protection and PWM control:
    • One fuel injector drivers, RDS(on) = 0.6 Ω, ILIMIT = 1.8 A, to drive typical 12 Ω high-impedance injectors
    • Relay 1 driver, RDS(on) = 0.4 Ω, ILIMIT = 3.0 A, to drive fuel pump
    • Relay 2 driver, RDS(on) = 1.5 Ω, ILIMIT = 1.2 A, to drive power relay
    • Lamp driver, RDS(on) = 1.5 Ω, ILIMIT = 1.2 A, to drive warning lamp or an LED
    • Programmable Tachometer Driver, RDS(on) = 20 Ω, Ishutdown = 60 mA, to drive a Tachometer display
  • One fuel injector drivers, RDS(on) = 0.6 Ω, ILIMIT = 1.8 A, to drive typical 12 Ω high-impedance injectors
  • Relay 1 driver, RDS(on) = 0.4 Ω, ILIMIT = 3.0 A, to drive fuel pump
  • Relay 2 driver, RDS(on) = 1.5 Ω, ILIMIT = 1.2 A, to drive power relay
  • Lamp driver, RDS(on) = 1.5 Ω, ILIMIT = 1.2 A, to drive warning lamp or an LED
  • Programmable Tachometer Driver, RDS(on) = 20 Ω, Ishutdown = 60 mA, to drive a Tachometer display
  • Innovative configurable VRS conditioning circuit, with two different parameter settings for engine cranking and running mode and an optional automatic mode to improve noise immunity in cranking conditions
  • K-line (ISO9141)
  • MCU reset generator and programmable watchdog
  • MCU Interface: 16-bit SPI and parallel interface with 5.0V IO capability
