onsemi NCV84120 high side driver
Self protected very low Iq high side driver with analog current sense 120 mOhm high side SmartFET
The NCV84120 is a fully protected single channel high side driver that can be used to switch a wide variety of loads, such as bulbs, solenoids, and other actuators. The device incorporates advanced protection features such as active inrush current management, over-temperature shutdown with automatic restart and an over-voltage active clamp. A dedicated Current Sense pin provides precision analog current monitoring of the output as well as fault indication of short to VD, short circuit to ground and OFF state open load detection. An active high Current Sense Enable pin allows all diagnostic and current sense features to be enabled.
