  • Protective circuit for an electronic device
    Patent number: 6538864
    Abstract: The protective circuit for an electronic device is located between a DC source (UV) and the circuit voltage input of the device (G). The protective circuit comprises the serial connection of a diode (DV) and a limiting resistor (RV). The series connected diode (DV) and the limiting resistor (RV) are connected and parallel with a control switch (S). A circuit voltage (UB, UA) of the device (G) is connected to a voltage monitoring element (W) which emits a switch signal (S) which closes the switch (S) when a determined minimum value of the circuit voltage (UB) is reached.
