Product Summary
The LT4256-2IS8#TR is a high voltage Hot Swap(TM) controller that allows a board to be safely inserted and removed from a live backplane. An internal driver of the LT4256-2IS8#TR drives an external N-channel MOSFET switch to control supply voltages ranging from 10.8V to 80V. Applications of the LT4256-2IS8#TR include: hot board insertion, electronic circuit breaker/power bussing, industrial high side switch/circuit breaker, 24V/48V industrial/alarm systems, ideally suited for 12V, 24V and 48V distributed power systems, 48V telecom systems.
