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 span style="text-decorati
