Abstract:
1. A monitoring and control circuit, comprising: a terminal operable for providing a monitoring signal indicative of a current flowing through a switch; comparator circuitry coupled to said terminal and operable for comparing said monitoring signal to a first threshold to provide a first signal according to the comparison between said monitoring signal and said first threshold, and operable for comparing said monitoring signal to a second threshold to provide a second signal according to the comparison between said monitoring signal and said second threshold; and a control module coupled to said switch and said comparator circuitry and operable for providing a control signal to control said switch to operate in a normal mode or a protection mode according to said first signal and said second signal so as to adjust said current, wherein in said protection mode, said control signal turns on and off said switch alternately to reduce said monitoring signal from said first threshold to said second threshold.
