The LT1640AL/LT1640AH are 8-pin, negative voltage Hot SwapTM controllers that allow a board to be safely inserted and removed from a live –48V 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 overvoltage threshold. A programmable electronic circuit breaker protects the system against shorts. The PWRGD (LT1640AL) or PWRGD (LT1640AH) signal can be used to directly enable a power module. The LT1640AL is designed for modules with a low enable input and the LT1640AH for modules with a high enable input. The LT1640AL/LT1640AH are available in 8-pin PDIP and SO packages.
