Abstract
A device for overvoltage protection includes a gate driver module and an overvoltage protection module. The gate driver module is configured to selectively activate a switching element to provide input power to a primary side winding of a transformer for generating a target output at a secondary side winding of the transformer. The overvoltage protection module is configured to determine a transition threshold based on a previously sensed supply voltage at a voltage supply pin configured to receive power for operating the circuit from a primary side auxiliary winding of the transformer and determine the circuit is operating in an overvoltage condition when a current supply voltage at the voltage supply pin exceeds the transition threshold, wherein the current supply voltage occurs at the supply pin after the previously sensed supply voltage.
