Wireless charging RX function

IP5568 supports wireless RX 5W / 10W charging function. TX and Rx share a coil and a resonant

capacitor, and switch TX and Rx modes by pressing the key (long press 2s). After IP5568 is powered on,

the wireless charging is TX mode by default.

When in Rx mode, the two LED indicators of wireless charging will flash together (the display

mode can be customized) to indicate that the wireless charging is working in Rx state. When using the

wireless RX charging function, the button function defaults to double-click shutdown without flashlight

function.

The RX output of wireless charging is directly connected to VIN network to provide power for

system charging. USB charging port is preferred for system charging. When Rx is working, insert usb-b or

usb-c, the wireless RX charging function will be automatically turned off, and the usb-b or usb-c will be

automatically switched to charge the system, and the wireless TX charging function will be turned on at

the same time
