The LT4250H is 8-pin, negative 48V Hot Swap™ controllers that allow 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 overvoltage threshold. A programmable current limit protects the system against shorts. After a 500μs timeout the current limit activates the electronic circuit breaker. The PWRGD (LT4250H) signal can be used to directly enable a power module. The LT4250H is designed for modules with a high enable input.
The LT4250H is available in 8-pin PDIP and SO packages
