onsemi NCV84003G High-Side eFuse
onsemi NCV84003G High-Side 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 an overtemperature shutdown with automatic latch-off. A current-sense pin on the onsemi NCV84003G provides precision analog current monitoring, fault indication, and readback of internal configuration and I2t status.
