ADM1171

Data Sheet 2.7 V to 16.5 V Hot Swap Controller with Current Sense Output ADM1171 FEATURES Controls supply rails from 2.7 V to 16.5 V 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 Current sense output Soft start inrush current control Automatic retry or latch-off during current fault Undervoltage lockout 8-lead, TSOT package APPLICATIONS Hot swap board insertion: line cards, raid systems Industrial high-side switches/circuit breakers Electronic circuit breakers GENERAL DESCRIPTION The ADM1171 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 enh...
