Product Summary
The LTC1647-1CS8#TR is a dual Hot Swap controller that permits 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. The applications of the LTC1647-1CS8#TR include Hot Board Insertion, Electronic Circuit Breaker, Portable Computer Device Bays, Hot Plug Disk Drive.
