  • Protective circuit
    Patent number: 9397492
    Abstract: A circuit for protecting an electronic functional unit connected to a data line against positive and negative overvoltages includes an analog switch arranged in the data line before the electronic functional unit and a voltage monitor, which is configured to control the analog switch, wherein the voltage monitor is configured to close the analog switch when no overvoltage occurs and to open the analog switch when an overvoltage occurs. The circuit also functions in an energy-saving mode and/or when no supply voltage is applied. The low resistance and bidirectionality of the data line are maintained.
    Type: Grant
