ADI LTC4210-2CS6#TRMPBF

A 6-pin SOT-23 hot swap controller that allows a board to be safely inserted and removed from a live backplane. An internal high side switch driver controls the GATE of an external N-channel MOSFET for a supply voltage ranging from 2.7V to 16.5V. The controller provides the initial timing cycle and allows the GATE to be ramped up at an adjustable rate. It features a fast current limit loop providing active current limiting together with a circuit breaker timer. The signal at the ON pin turns the part on and off and is also used for the reset function. Available in two options: automatic retry or latch off on current fault.
