CHARGING CIRCUIT, CHARGING CHIP, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2022/199211

A1

The present application provides a charging circuit, a charging chip, and an electronic device. The present application can solve the problem in an electronic device using two batteries that one of the batteries cannot be fully charged, resulting in relatively small available capacity of the batteries of the electronic device. The charging circuit comprises a voltage converter, a controller, a first switching element, and a second switching element. A first end of the first switching element is used for being coupled to a first battery, and a first end of the second switching element is used for being coupled to a second battery. A second end of the first switching element and a second end of the second switching element are both coupled to a first end of the voltage converter to charge the first battery and the second battery. A second end of the voltage converter is used for being couple to a power adapter. In this way, charging currents of the first battery and the second battery can be controlled by means of the first switching element and the second switching element respectively, so that both the first battery and the second battery can be fully charged, thereby improving the available capacity of the batteries in the electronic device, and improving the service performance of the batteries.
