Features

  • Designed to operate 5.5 V ≤ VPWR ≤ 24.5 V
  • 8-bit SPI for control and fault reporting, 3.3/ 5.0 V compatible
  • Outputs are current limited (0.8 A to 2.0 A) to drive incandescent lamps
  • Output voltage clamp is +45 V (typical) (low side drive) and -20 V (typical) (high side drive) during inductive switching
  • Internal reverse battery protection on VPWR
  • Loss of ground or supply will not energize loads or damage IC
  • Maximum 5.0 µA IPWR standby current at 13 V VPWR up to 95 °C
  • RDS(ON) of 0.55 Ohm at 25 °C typical
  • Short circuit detect and current limit with autoretry
  • Independent over-temperature protection
  • 32-pin SOICW has pins 8, 9, 24, and 25 grounded for thermal performance
