LTC1421 - Hot Swap Controller

Description

The LTC®1421/LTC1421-2.5 are Hot SwapTM controllers that allow 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.

LTC1421/LTC1421-2.5 Hot Swap Controller FEATURES s s s s s s s s s DESCRIPTION The LTC®1421/LTC1421-2.5 are Hot SwapTM controllers that allow 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. 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 reset output can be used to generate a system reset when the power cycles or a fault occurs.
