The ADM1172 is a hot swap controller that 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 over-current 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-
Allows protected board removal and insertion to a live backplane
External sense resistor provides adjustable analog current limit with circuit breaker
Peak fault current limited with fast response
Charge pumped gate drive for external N-FET switch
Power-fail comparator
Automatic retry or latch-off during current fault
Undervoltage lockout
8-lead, TSOT package
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 V to 16.5 V.
