Abstract:
1. An electronic device comprising: a power source; a power management module connected to the power source to receive a voltage; a MCU connected to the power management module; and a power control circuit comprising: wherein, the second switch unit has a first status in which the second switch unit outputs a first control signal to switch on the first switch, to connect the MCU to the power source for enabling the MCU to receive power; and the second switch unit further outputs a boot signal to the MCU, the MCU outputs a power-on signal according to the boot signal to control the power management module to power the electronic device; the second switch unit has a second status in which the second switch unit outputs a shutdown signal to the MCU, and the MCU outputs a power-off signal according to the shutdown signal, to control the power management module to go through the shutdown procedure for the electronic device; and the second switch module further outputs a second control signal to switch off the first switch after a determined period of time, to cut off an input voltage from the power source to the MCU.
