The ISL6141 is an 8-pin, 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 Under-Voltage threshold, or greater than the Over-Voltage threshold. The IntelliTrip™ electronic circuit breaker and programmable current limit features protect the system against short circuits. When the Over-Current threshold is exceeded, the output current is limited for 600µs before the circuit breaker shuts down the FET. If the fault disappears before the 600µs time-out, normal operation resumes. In addition, the IntelliTrip™ electronic circuit breaker has a fast Hard Fault shutdown with a threshold set at 4 times the current limit value. When activated, the GATE is immediately turned off and then slowly turned back on for a single retry (soft-start). The active low PWRGD signal can be used to directly enable a power module (with a low enable input). The ISL6151 is the same device but has an active high PWRGD output.
