Product Summary
The LTC1422CS8#TR is an 8-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 2.7V to 12V. A programmable electronic circuit breaker protects against shorts. The RESET output can be used to generate a system reset when the supply voltage falls below a programmable voltage. The ON pin can be used to cycle the board power or to generate a soft reset. The applications of the LTC1422CS8#TR include Hot Board Insertion, Electronic Circuit Breaker.
