Product Summary
The LTC1642CGN#TR is a 16-pin Hot Swap 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. The SENSE pin allows foldback limiting of the load current, with circuit breaker action after a programmable delay time. The delay allows the part to power-up in current limit. The applications of the LTC1642CGN#TR include Hot Board Insertion, Electronic Circuit Breaker.
