80 A high-side switch for automotive power distribution
The load supply range spans 8 V to 18 V, covering nominal 12 V automotive bus conditions including cold-crank and load-dump transients. The inverting On/Off interface accepts a logic-level enable signal, and the device requires no external Vcc supply for its internal bias.
Fault protection suite and load diagnostics
Integrated fault protection includes adjustable current limiting, open-load detection, over-temperature shutdown, and under-voltage lockout (UVLO). The adjustable current limit lets the designer set the trip threshold below the 80 A absolute maximum to protect the wiring harness and load. Open-load detection reports a disconnected load during the off-state, useful for lamp-out or actuator-disconnect diagnostics in body-control modules.
