  • Protection circuit with bidirectional surge protection
    Patent number: 11128130
    Abstract: A protection circuit is provided. A control circuit receives an input voltage. In a case that the input voltage is lower than a negative threshold voltage, the control circuit outputs a first control voltage to a surge bleeder circuit through a first output end of the control circuit, to control the surge bleeder circuit to discharge the input voltage and output a first bleeder current. In a case that the input voltage is higher than a positive threshold voltage, the control circuit outputs a second control voltage to the surge bleeder circuit through a second output end of the control circuit, to control the surge bleeder circuit to discharge the input voltage and output a second bleeder current.
    Type: Grant
