onsemi NIS6420 eFuse

onsemi NIS6420 Electronic Fuse is a cost-effective, resettable fuse that enhances the reliability of a hard drive from catastrophic and shutdown failures. The fuse is designed to protect the downstream circuitry against an overcurrent event. It limits the current while protecting against high inrush current, and monitors load current in real-time.
