electronic fuse (e-Fuse)

Electronic Fuses, e-Fuses or eFuses, are electronic fuses designed as integrated circuits that perform the functions of conventional fuses.

E-fuses are electronic circuits that can consist of diodes, power transistors, FETs,PTCs and fuses and are housed in a DFN package or in flip- chip technology. They protect electronic circuits, systems, and equipment against overvoltage, overcurrent, short circuit, reverse current, inrush current, and reverse polarity, and have a low inrush resistance whose input terminal is connected to the load. These solid-state electronic fuses are also known as intelligent power devices (IPDs).

An e-Fuse operates like a standard fuse and detects overload and overvoltage conditions. In the event of a voltage overload or excessive thermal load, the load can be disconnected. The overload is limited via external resistors.
