Self-Protected High Side eFuse With IDLE Mode, I2t Protection, Capacitive Charging Mode & Analog Current Sense

Active

Overview

The NCV84003G eFuse is a fully protected single channel high side driver that can replace mechanical fuses and provide power in a smart power distribution architecture. It can also switch a wide variety of loads, such as bulk capacitors, bulbs, solenoids, and other actuators. The device incorporates advanced features designed for zonal applications such as a smart low power IDLE mode, a dedicated capacitive load charging mode, adjustable overcurrent thresholds and built-in I2t profiles for replacing conventional melting fuses. The device also features overtemperature shutdown with automatic latch-off. A Current Sense pin provides precision analog current monitoring, fault indication, as well as readback of internal configuration and I2t status.
