Product Summary

The LTC1647-1CS8#TRPBF is a dual Hot SwapTM controller 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 controls the MOSFET gates for supply voltages ranging from 2.7V to 16.5V. A programmable electronic circuit breaker protects against overloads and shorts. The ON pins are used to control board power or clear a fault.
