Abstract
A switch control circuit, for controlling a path switch and a current sense resistor connected in series between an input voltage and an output voltage, includes: an amplifier, which controls the gate voltage of the path switch based on a voltage drop across the current sense resistor to perform current-limited soft start; a slope detection circuit, coupled to the output voltage, for monitoring the rising slope of the output voltage; and a pull-down switch, coupled between the gate of the path switch and a disabling potential. When the slope detection circuit detects that a rising slope of the output voltage is below a preset slope threshold, the pull-down switch is triggered to conduct, thereby turning off the path switch.
