The ADM1171 is a Hot Swap controller that allows a board to be safely inserted and removed from a live backplane. This is achieved using a pass FET with a current control loop that monitors the input current using a sense resistor. An internal charge pump is used to enhance the gate of theexternal high side 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. The ADM1171 operates with a supply voltage ranging from 2.7V to 16.5V. During an overcurrent condition the timer capdetermines the amount of time the FET will remain in this condition. The ON (ON/CLR) pin is the enable input for the device and also acts as a latched fault reset for the ADM1171-2 model. The magnitude of the current flowing through the Sense resistor can be determined by the voltage on the CSOUT pin The SS pin allows the user to control the soft start profile of the current ramp at start-up via an external capacitor. This device is available in two options: the ADM1171-1 will automatic retry for over-current fault and the ADM1171-2 will latch-off for an over-current fault. The ADM1171 is packaged in an 8-lead TSOT package.
