Datasheet	MAX4919B Datasheet

The MAX4919B/MAX4920B/MAX4921B overvoltage protection controllers protect low-voltage systems against high-voltage faults up to +28V.

An internal 1.8A (min) pFET with low RON (100mΩ) switches a battery to the load and also protects the battery against short-circuit faults.

When a short circuit occurs, the current through the internal pFET is limited for a blanking period.
