LT1640L, LT1640H Negative Voltage Hot Swap Controller FEATURES s s s s s s s DESCRIPTION The LT®1640L, LT1640H is an 8-pin, negative voltage Hot SwapTM controller that allows a board to be safely inserted and removed from a live backplane. Inrush current is limited to a programmable value by controlling the gate voltage of an external N-channel pass transistor. The pass transistor is turned off if the input voltage is less than the programmable undervoltage threshold or greater than the overvo
