Key features
  • AEC-Q100 qualified
  • ISO26262 compliant, covering ASIL-B safety integrity level
  • Octal half-bridge, or quad H-bridge, pre-driver
  • Independent channel driver up to 8 high-side or 8 low-side
  • Driving logic permits any H-bridge configuration, pairing different half-bridges, using the internal gate drivers (GHx/SHx/GLx can be associated to any GHy/SHy/GLy)
  • Support logic level and standard level MOSFETs
  • Control of reverse battery protection MOSFET
  • Fully configurable half-bridge driver in case of fault occurrence
  • Generator mode for power trunk/tailgate applications
  • Supporting indirect current measurement of external MOSFETs
  • SPI configurable overvoltage threshold
  • Adaptive MOSFET gate control
    • Three steps gate control of external HS/LS
    • Improved electromagnetic emission
    • Programmable gate current up to 120 mA
    • Reduced switching losses in PWM mode
  • Vds monitoring
  • Low IQ (1.05 μA) in reset mode
  • High-side and low-side capable of protection and diagnosis
  • Four external diodes control, needed for assisting calibration of indirect current measurement, can be used for steady - temperature monitoring
  • Drain-source monitoring for short circuit detection
  • Overtemperature warning and shutdown
  • Timeout watchdog for MCU control
  • Detailed off-state diagnostic (open load, short circuit to battery or short circuit to GND) via SPI
  • Three PWM inputs
    • High-side and low-side PWM capable
    • Active freewheeling
    • Up to 50 kHz PWM frequency
