Key features
  • AEC-Q100 qualified
  • Full ISO26262 compliant, ASIL-B systems ready
  • General
    • Eight LS drivers
    • 16-bit SPI interface for outputs control and for diagnosis data communication
    • Daisy chain compatible and available even with 8-bit SPI
    • 2 parallel input pins with input mapping functionality
    • Cranking capability down to VBATT = 3 V
    • Digital supply voltage range compatible with 3.3 V and 5 V MCU
    • Bulb inrush mode (BIM) to drive 2 W lamps and electronic loads
    • Two independent internal PWM generators for MCU offloads and to drive LEDs
    • Very low quiescent current (with usage of IDLE pin)
    • Limp-home mode (with usage of IDLE and IN pins)
    • Safety features Temperature sensor and monitoring Serial communications using address feedback, 1 parity bit, frame counter and short frame detection
    • Fail-safe activation via input pins
    • Safe operation at low battery voltage (cranking)
  • Protective functions
    • Overcurrent latch off
    • Lower supply voltage range for extended operation
    • Electrostatic discharge (ESD) protection
