Abstract
A power control apparatus is provided that receives an input power voltage from a power source and supplies a corresponding output power voltage to a device. The apparatus contains a counter, a processor, and a switch. The counter inputs a power control signal and outputs a count signal that corresponds to a lapsed time from when the power control signal is input. The processor inputs the count signal and outputs a time out signal. The time out signal has a first value if the lapsed time and a predetermined time have a certain relationship, and the time out signal has a second value if the lapsed time and predetermined time do not have the certain relationship. The switch receives the input power voltage from the power source and the time out signal. If the time out signal has the second value, the switch does not output the output power voltage to the device. On the other hand, if the input power voltage is received and the time out signal has the first value, the switch outputs the output power voltage to the device. In addition, a method performed by the power control apparatus is provided.
