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.
