Overvoltage protection circuit with digital control
A device for digitally protecting against an overvoltage event may include a front-end circuit, an overvoltage protection circuit, and a protection switch. The protection switch may be coupled to the overvoltage protection circuit and may be configured to decouple the front-end circuit from an external medium, in response to a clamp signal. The overvoltage protection circuit may be configured to detect the overvoltage event at one or more nodes of a circuit. In response to the detection of the overvoltage event, the overvoltage protection circuit may generate the clamp signal to activate the protection switch.
