Abstract

Embodiments of this application provide a wireless charging system, a chip, and a wireless charging circuit. The wireless charging system includes an electronic device and a stylus, where the electronic device is configured to wirelessly charge the stylus; and the stylus includes a wireless charging circuit. The wireless charging circuit includes a first coil, a chip, and a first battery, the chip includes a rectifier, a charger unit, a micro-control unit, and a protocol encoding/decoding unit. The charger unit includes a voltage-stabilizing charging circuit, a boost charging circuit, or a switched capacitor charging circuit; and the charger unit is configured to charge the first battery by using the direct current signal from the rectifier. For the stylus, energy is coupled from the coil, passes through the chip, and then is directly output to a battery of the stylus.
