Product Summary
The LT4254CGN#TR is a high voltage Hot Swap controller that allows a board to be safely inserted and removed from a ive backplane. An internal driver of the LT4254CGN#TR controls the high side N-channel MOSFET gate for supply voltages ranging from 10.8V to 36V. The LT4254CGN#TR features an open-circuit detect (OPEN) output that indicates abnormally low load current conditions. Applications of the LT4254CGN#TR include: Hot Board Insertion, Electronic Circuit Breaker/Power Bussing, Industrial High Side Switch/Circuit Breaker, 24V Industrial/Alarm Systems, 12V and 24V Distributed Power Systems.
