Introduction to a wireless power transmitter controller IP6806

Article Source：injoinic | Author：Kinri Energy | Issuing Time：2022.07.06
IP6806  is manufacured by Injoinic Technology.



DESCRIPTION

IP6806 is a wireless power transmitter controller SoC that integrates all required functions for the latest WPC Qi V1.2.4 specifications compliant wireless power transmitter design. Support A11 coil, support 5W, Apple 7.5W, Samsung 10W charging. It used analog PING to detect a RX wireless device for charging with low standby power.

Once RX device is detected, the IP6806 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. IP6806 terminate power transfer when RX device is fully charged. IP6806 integrate full-bridge driver and full bridge power MOS, includes voltage and current two-way ASK demodulation module, and input overvoltage/current protection and FOD module.

IP6806 is a highly integrated SoC for small-size and low bom cost solutions and reduced time-to-market.
