Abstract
A control method executing a power-off detection operation is provided. An operation voltage provided by a power circuit is detected. In response to the operation voltage being equal to the first detection value, the count value is adjusted. In response to the operation voltage being equal to the second detection value, the first detection value, the second detection value, and the count value are calculated to generate a first slope. A first power-off speed at which the operation voltage drops to the reset voltage is estimated according to the first slope. In a test mode, the first power-off speed is output to a test machine. The test machine determines whether the power circuit is working normally according to the first power-off speed.
