Product Summary
The LT4250HIS8#TR is a 8-pin, negative 48V Hot Swap (TM) controller that allows a board to be safely inserted and removed from a live backplane. Inrush current of the LT4250HIS8#TR is limited to a programmable value by controlling the gate voltage of an xternal N-channel pass transistor. And LT4250HIS8#TR for modules with a high enable input. Applications of the LT4250HIS8#TR include: Central Office Switching, -48V Distributed Power System, Negative Power Supply Control.
