Overview

  • Designed to operate 5.5 V  VPWR  26 V
  • Switch input voltage range -14 V to VPWR, 40 V Max
  • Interfaces directly to MPU using 3.3 V/5.0 V SPI protocol
  • Selectable wake-up on change of state
  • Selectable wetting current (16 or 2.0 mA)
  • Eight programmable inputs (switches to supply or ground)
  • 14 switch-to-ground inputs
  • Typical standby current - VPWR = 100 A and VDD = 20 A
  • Active interrupt (INT) on change-of-switch state
