The is a positive low voltage Hot Swap Controller allows a board to be safely inserted and removed from a live backplane. It controls load voltages ranging from 0V to 6V and isolates a severe fault with instantaneous analog current limiting. An internal high side switch driver controls the gate of an external N-channel MOSFET. An adjustable soft-start limits the rate of change of the inrush current at start-up for a large load capacitor. Together with an analog current limit amplifier, an electronic circuit breaker with adjustable response time provides dual level overcurrent protection. No external gate capacitor is required for the analog current limit loop compensation. The FB pin monitors the output supply voltage and signals the RESET output pin. An ON pin provides on/off control and a FAULT pin indicates the fault status.
