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
