Support A11 coil, support 5W charging. It used analog PING to detect a RX wireless device for charging with low standby power. Once RX device is detected, the IP6805U establish a communication with the RX wireless device and controls the coil power transfer by adjusting operation frequency, depended on calculating the data packages, received from RX device, with PID algorithm. IP6805U terminate power transfer when RX device is fully charged. IP6805U integrate full-bridge driver and full bridge power MOS, include...
