    摘要: A power switch circuit providing voltage to an output port is provided. The switch circuit includes a single power supply, a switch unit, a controlling unit, and a logic unit. The switch unit is connected between the single power supply and an output port and capable of being turned on and off alternatively for continuing or discontinuing power from the single power supply to the output port; the single power supply provides power to the output port. The controlling unit is configured for generating a voltage controlling signal and transmitting the voltage controlling signal to the logic unit. The logic unit receives and inverts the voltage controlling signal, and outputs the inverted voltage controlling signal to turn on or turn off the switch unit.

    摘要: A battery management system includes a power converter, a first switch, a second switch, a first detecting unit, and a CPU. The power converter is configured to divide current provided by the power supply into a first and a second output current, according to a working current of a system load in a normal state, the first output current is used to power the system load, and the second output current is used to charge a battery unit. The CPU is configured to determine whether the value of current detected by the first detecting unit is greater than a threshold value, and further controls turning on the first switch to power the system load using the first output current, and turn on the second switch to charge the battery unit using the second output current.

    摘要: An electronic device includes a switching circuit, a hardware (HD) indication unit, a LED module, a software (SF) indication unit, a first control switch electrically connected between a power port, an anode of the LED module, and the HD indication unit, and a second control switch connected between a cathode of the LED module, the SF indication unit and ground. When the electronic device is charged in a powered off state, the cathode of the LED module is grounded, the HD indication unit directs the first control switch to turn on and off alternatingly, and the LED module flashes accordingly. When the electronic device is charged in a powered state, the anode of the LED module is at a high voltage level, and the SF indication unit directs the second control switch to turn on and off alternatingly, and the LED module flashes accordingly.
