MAX5977B - 1V to 16V / Single-Channel Hot-Swap Controllers

Download the MAX5977B datasheet PDF. This datasheet also covers the MAX5977A variant, as both devices belong to the same 1v to 16v / single-channel hot-swap controllers family and are provided as variant models within a single manufacturer datasheet.

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.

19-5553; Rev 1; 1/11 TION KIT EVALUA BLE A IL A V A 1V to 16V, Single-Channel, Hot-Swap Controllers with Precision Current-Sensing Output 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.
