Abstract:
A capacitor circuit with surge protection that is selectively connected between a voltage source and a device includes a first capacitance element has one end that communicates with a first terminal of the voltage source. A first transistor has a first terminal that communicates with an opposite end of the first capacitance element and a second terminal that communicates with a second terminal of the voltage source. A control terminal of the first transistor communicates with a capacitor enable signal that provides a controlled turn-on to limit current surge and turns off the first transistor when voltage surge is detected.
