Abstract

This application relates to the technical field of wireless chargers, and more particularly to a bidirectional wireless charging circuit and electronic device. It includes: a device interaction port, a main control module, a transmitting module, a receiving module, and a resonant sensing module. The device interaction port is connected to a first terminal of the main control module, a second terminal of the main control module is connected to a first terminal of the transmitting module, and a third terminal of the main control module is connected to a first terminal of the receiving module. This triggers a corresponding signal transmission / reception mode based on the type of device currently connected to the device interaction port. The second terminal of the transmitting module is connected to the input terminal of the resonant sensing module, and the second terminal of the receiving module is also connected to the input terminal of the resonant sensing module. The resonant sensing module is equipped with an induction coil and, in response to the current signal transmission / reception mode, configures the device interaction port to either charging or discharging mode. This application provides a wireless charging solution that supports flexible power supply between devices, thereby improving ease of use.
