Product Summary

The LTC1421CSW#TR is a Hot Swap 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 N-channel gates for supply voltages ranging from 3V to 12V. A programmable electronic circuit breaker protects against shorts. Warning signals indicate that the circuit breaker has tripped, a power failure has occurred or that the switch drivers are turned off. The applications of the LTC1421CSW#TR include Hot Board Insertion, Electronic Circuit Breaker.
