WIRELESS CHARGING CIRCUIT AND DEVICE

This application provides a wireless charging circuit and a device. The wireless charging circuit includes a power supply module, an inverter module, and a first coil component; the first coil component includes at least one coil; the power supply module is connected to the inverter module, and the inverter module is connected to the first coil component; the power supply module is configured to: output a direct current signal to the inverter module; and the inverter module is configured to: convert the direct current signal into an alternating current signal at a target resonant frequency, and output the alternating current signal to the first coil component, where the target resonant frequency is at an MHz level. In this application, a stylus can obtain electric energy from a power supply device without being clung to the power supply device.
