  • Electronic device and method of controlling electronic device
    Patent number: 7882392
    Abstract: An electronic device includes a power supply unit that generates plural output voltages from an input voltage and outputs the various output voltages from respective plural power supply channels, a voltage detecting unit that monitors voltages of two power supply channels among plural power supply channels which are different in decreases of the output voltage in the case that the input voltage is cut off, outputs a first detecting signal upon detecting a decrease in voltage of a first power supply channel having a fast decrease to a first threshold and outputs a second detecting signal upon detecting a decrease in voltage of a second power supply channel having a slow decrease to a second threshold, and a control unit that saves data upon receiving the first detecting signal and stops an operation of the electronic device upon receiving the second detecting signal.
