Features

  • Fully integrated, single- or dual pyro-fuse driver design
  • Reduced wiring harness effort in conjunction with TI's contactor drivers and pack monitors
  • SPI for configuration, diagnostics, and deployment
  • Level or heart beat, rapid hardware pin trigger function by pack-monitor overcurrent detection or collision sensors
  • Optional energy reservoir capacitor integration
  • ASIL-C safety goals to prevent unexpected battery pack disconnection and availability of disconnection function
  • Reservoir storage diagnostics, output and short-to-supply diagnostics, built-in self-test, load (pyro) diagnostics
