GENERAL DESCRIPTION
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-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.
The ADM1172 also features a power-fail comparator. The
voltage on the PFI pin is compared with an internal 0.6 V
reference, and the output of this comparator is presented on
the PFO pin. This device is available in two options: the
ADM1172-1 with automatic retry for overcurrent fault and the
ADM1172-2 with latch-off for an overcurrent fault. Toggling
the ON (ON-CLR) pin resets a latched fault. The ADM1172 is
packaged in an 8-lead TSOT.
