Self Protected Very Low Iq High Side Driver with Analog Current Sense NCV84140 The NCV84140 is a fully protected single channel high side driver that can be used to switch a wide variety of loads, such as bulbs, www.onsemi.com solenoids, and other actuators. The device incorporates advanced protection features such as active inrush current management, overtemperature shutdown with automatic restart and an overvoltage 8 active clamp. A dedicated Current Sense pin provides precision analog current monitoring of the output as well as fault indication of short to 1 V , short circuit to ground and OFF state open load detection. An D SOIC8 active high Current Sense Enable pin allows all diagnostic and current CASE 75107 sense features to be enabled.
