Abstract
Power monitors, power supply circuits, and methods for operating a power supply. The method includes determining a voltage of a power rail provided to a load device from the power supply. The method also includes detecting that the voltage of the power rail is greater than or equal to an over-voltage threshold. The method further includes incrementing an over-voltage counter when the voltage of the power rail is detected as being greater than or equal to the over-voltage threshold. The method also includes detecting that the over-voltage counter is equal to a threshold value. The method further includes generating an interrupt signal when the over-voltage counter is detected as being equal to the threshold value.
