General Description

The MAX5977A/MAX5977B hot-swap controllers provide complete protection for systems with a 1V to 16V singlesupply voltage.

During the initial insertion, the hot-swap controllers limit the inrush current from damaging the board or from shorting out the backplane.

When the input voltage is above the undervoltage threshold and below the overvoltage threshold, a 5FA current source powered from the internal 5V charge pump drives the gate of an external n-channel MOSFET, providing a slow turn-on response.
