LTC1642IGN(V2) 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 a programmable rate. A high side switch driver controls the N-channel gate for supply voltages ranging from 2.97V to 16.5V.
