Product Summary
The LTC1421CG-2.5#TR is a Hot SwapTM controller that allows 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. The applications of the LTC1421CG-2.5#TR include Hot Board Insertion, Electronic Circuit Breaker.
