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 overvoltage

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.
