  • Over-voltage protection circuit and associated method
    Patent number: 10050615
    Abstract: An over-voltage protection circuit for a transistor switch has an error detecting circuit, a dummy load circuit and a driving circuit. The error detecting circuit has a first input terminal; and a second input terminal configured to receive a reference signal. The dummy load circuit is configured to establish a conductive path between the output terminal of the transistor switch and ground. The driving circuit is configured to increase the on-resistance of the transistor switch if the voltage difference between the second terminal of the error detecting circuit and the first terminal of the error detecting circuit is smaller than a calculated value.
