onsemi NIV3071, NIS3071

NIV3071MTW3TWG is a 4-channel, 60V, 2.5A per channel eFuse. It protects downstream loads from output shorts, overloads, and overcurrent events. Each channel is in a high-side configuration and is independently controlled by its corresponding enable pins. It communicates status via a common active low fault pin. This eFuse features an internal soft start delay, trip time control, and an adjustable current limit setting common to all channels. It is used in applications such as automotive body control modules, power distribution boxes, automotive zonal controllers, load/harness protection, automotive low medium power loads, general purpose high side load switches, power amplifier protection, motor drive protection, telecom equipment, 8V to 60V industrial.

Key features
