描述
The ISL6140 is an 8 Ld, negative voltage hot plug 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 undervoltage threshold, or greater than the overvoltage threshold. A programmable electronic circuit breaker protects the system against shorts. The active low PWRGD signal can be used to directly enable a power module (with a low enable input). The ISL6150 is the same part, but with an active high PWRGD signal.

Negative Voltage Hot Plug/Hot Swap Controller Evaluation Board
The ISL6140/41EVAL1 evaluation board is used to evaluate the ISL6140 and ISL6141 8-pin, negative voltage hot plug/hot swap controllers. The ISL6140/41EVAL1 board set is made up of three boards: a bus board for input -48V power bus, control board for IC hot-plug functions and load board for load...
