 |  | The LTC1421/LTC1421-2.5 are Hot SwapTM controllers that allow a board to be safely inserted and removed from a live backplane. Using external N-channel pass transistors, the board supply voltages can be ramped up at a programmable rate. Two high side switch drivers control the Nchannel gates for supply voltages ranging from 3V to 12V. |  |  Click here to download LTC1421ISW Datasheet*)
