The MAX4793EUK+T is a current-limiting IC from Analog Devices designed to protect downstream circuitry from overcurrent faults on supply rails between 2.3 V and 5.5 V. It limits output current to 300 mA, acting as a precision electronic fuse that resets once the fault clears — no fuse replacement needed.
It is used in USB ports, peripheral power switches, and general-purpose overcurrent protection where a resettable electronic fuse is preferred over a physical fuse.
