Abstract
The present disclosure provides a method and device for overvoltage protection. Specifically, the present disclosure provides an overvoltage protection device which provides a feedback loop for electronic components such as amplifiers and digital to analog converters which require feedback. The overvoltage protection device also includes overvoltage switches in both the signal and feedback channels, which may be opened by a fault detector in the event of an overvoltage. The device also includes an overvoltage feedback channel coupled between the signal and feedback channels, and which also includes a switch which may be closed in the event of an overvoltage event. As such, the overvoltage device provides a closed loop feedback channel during an overvoltage event.
