  • Patent number: 11804706
    Abstract: An over-voltage protection circuit includes an over-voltage detection circuit, a voltage generator and a switch for providing over-voltage protection between two pins of a USB Type-C port. The over-voltage detection circuit provides an over-voltage signal according to the level of the second pin. The switch includes a first end coupled to the first pin, a second end coupled to the second pin and a control end coupled to a control signal. When the over-voltage signal does not indicate an over-voltage occurrence at the second pin, the voltage generator provides the control signal having a first level for operating the switch in a first region. When the over-voltage signal indicates an over-voltage occurrence at the second pin, the voltage generator adjusts the control signal to a second level for cutting off the switch. The switch operates in a second region after the over-voltage occurrence and before the switch is cut off.

    Abstract: A gate driving circuit for providing a high driving voltage includes a first N-type high-voltage transistor and a second N-type high-voltage transistor connected in series between a driving voltage output node and a system low-voltage source. A voltage difference between a system high-voltage source and the system low-voltage source is greater than a withstand voltage of the first or second N-type high-voltage transistor. When the driving voltage output node is to output a system high voltage, the first N-type high-voltage transistor and the second N-type high-voltage transistor are turned off. Deep N-type well regions of the first N-type high-voltage transistor and the second N-type high-voltage transistor are applied with a first bias voltage. A voltage difference between the first bias voltage and the system low-voltage source is smaller than an interface breakdown voltage between the deep N-type well region and a P-type well region of the second N-type high-voltage transistor.
