Product Overview

The ADM1172-1AUJZ-RL7 is a Hot Swap Controller with power-fail comparator. It safely enables a printed circuit board to be removed and inserted to a live backplane. This is achieved using an external N-channel power MOSFET with a current control loop that monitors the load current through a sense resistor. An internal charge pump is used to enhance the gate of the N-channel FET. When an overcurrent condition is detected, the gate voltage of the FET is reduced to limit the current flowing through the sense resistor. During an overcurrent condition, the TIMER pin capacitor determines the amount of time the FET remains at a current limiting mode of operation until it is shut down. The ON (ON-CLR) pin is the enable input for the device and can be used to monitor the input supply voltage. The ADM1172 operates with a supply voltage ranging from 2.7 to 16.5V. It features a power-fail comparator and automatic retry for overcurrent fault.
