Maxim’s MAX5977A/MAX5977B hot-swap controllers provide complete protection for systems with a 1 V to 16 V single-supply voltage. During initial insertion, the devices limit the inrush current from damaging the board or from shorting out the backplane. When the input voltage is above the under-voltage threshold and below the over-voltage threshold, a 5 μA current source powered from the internal 5 V charge pump drives the gate of an external n-channel MOSFET, providing a slow turn-on response. An internal current-sense amplifier in the IC monitors the current across an external shunt resistor, providing current sensing for wide input-sense voltage range. The devices provide two levels of over-current circuit-breaker protections: a fast-trip threshold for fast turn-off and a lower slow-trip threshold for a delayed turn-off.
