Abstract: An electronic device selectively coupled to a first charger and/or a second charger includes a power supply interface, a first comparator, a second comparator, a controller, a first switch circuit, and a second switch circuit. The power supply interface receives a first input voltage and a second input voltage. The first comparator compares the first input voltage with a first reference voltage, so as to generate a first comparison voltage. The second comparator compares the second input voltage with a second reference voltage, so as to generate a second comparison voltage. The controller generates a first control voltage and a second control voltage according to the first comparison voltage and the second comparison voltage. The first switch circuit is selectively enabled or disabled according to the first control voltage. The second switch circuit is selectively enabled or disabled according to the second control voltage.

Abstract: An electronic device is provided. The electronic device includes a power supply module, a system load, a soft start unit, a unidirectional conducting unit and a connector. The system load is electrically coupled with the power supply module. The soft start unit is electrically coupled with the system load and the power supply module. The unidirectional conducting unit is electrically coupled between the soft start unit and the power supply module, so as to prevent the energy from the power supply module from entering the soft start unit. The connector has a power input terminal. The power input terminal is electrically coupled with the soft start unit.

Abstract: A dockable device and a power method thereof are provided. The dockable device includes a main device, a main device battery, a connector, a switch and a voltage down-converter. The connector may be coupled to a docking device. The switch, coupled to the main device battery, is configured to be closed to provide power to the main device from the main device battery. The voltage down-converter is configured to provide power with a backup voltage to the main device, wherein the backup voltage is less than a discharge voltage output by a fully discharged main device battery.

Abstract: An operating circuit including a system circuit and a power control circuit is provided. The system circuit operates according to the voltage of the node. The power control circuit includes a first connection port, a second connection port, a first always-on switch, a second always-on switch, a first current limiter, and a second current limiter. The first connection port is configured to receive first power provided by a first external device. The second connection port is configured to receive second power provided by a second external device. The first always-on switch is coupled to the first connection port to transmit the first power. The second always-on switch is coupled to the second connection port to transmit the second power. The first current limiter is coupled between the first always-on switch and the node. The second current limiter is coupled between the second always-on switch and the node.
