The LTC®1647-1/LTC1647-2/LTC1647-3 are dual Hot SwapTM controllers that permit a board to be safely inserted and removed from a live backplane.

Using external N-channel MOSFETs, the board supply voltages can be ramped up at a programmable rate. A high side switch driver of LTC1647-1/LTC1647-2/LTC1647-3 controls the MOSFET gates for supply voltages ranging from 2.7V to 16.5V. A programmable electronic ircuit breaker protects against overloads and shorts. The ON pins are used to control board power or clear a fault.
