Overview

Protects against overcurrent, short circuit, overvoltage, reverse connection and surge events.

 

The precise and fast design of the eFuses enables real-time detection of faults and isolation of loads. It automatically resumes operation after the state is stable, and can protect against overcurrent, short circuit, overvoltage, reverse connection and surge events. The Silergy eFuses adopts a compact package design, which helps to improve system efficiency, reduce the number of components, and enhance overall stability.
