MAX5923 - +60V Simple Swapper Hot-Swap Switch

The MAX5923 is a fully integrated Simple Swapper™ hot-swap switch for positive supply rails.

The device allows the safe insertion and removal of circuit cards into live backplanes or ports without causing glitches on the power-supply rail.

• that monitor fault conditions and prevent damage to the internal MOSFET. The MAX5923 monitors three parameters for fault conditions: zero current, overcurrent, and thermal overload. The output overcurrent limit counts the time the MAX5923 spends in an overcurrent condition and shuts down the pass transistor if the current limit is exceeded for the overcurrent time limit. The zero-current detection counts the time the output current is below the zero-current threshold and shuts down the pass tran.
