1. A method for operating a power supply, the method comprising:
determining a voltage of a power rail provided to a load device from the power supply;
detecting that the voltage of the power rail is greater than or equal to an over-voltage threshold;
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;
detecting that the over-voltage counter is equal to a threshold value; and
generating an interrupt signal when the over-voltage counter is detected as being equal to the threshold value.
