LTC1642IGN Datasheet PDF - Linear Technology

DESCRIPTION
The LTC®1642 is a 16-pin Hot SwapTM controller that allows a board to be safely inserted and removed from a live backplane. Using an external N-Channel pass transistor, the board supply voltage can be ramped up at an adjustable rate. A high side switch driver controls the N-Channel gate for supply voltages above 2.97V.
