Product Introduction

IP6809 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 3 coils applications. support A28 coil, MP-A28 coil, MP-A2 coil..support 5W, Apple 7.5W, Samsung 10W, 15W charging. It used analog PING to detect a RX wireless device for charging with low standby power. IP6809 determines the position of the receiver by switching the different working coils to perform analog ping and detecting the signal strength, and selects the coil with the strongest signal to perform the charging action.Once RX device is detected, the IP6809 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. IP6809 terminate power transfer when RX device is fully charged.

IP6809 integrate full-bridge driver, includes voltage and current two-way ASK demodulation module, and input overvoltage/current protection and FOD module. IP6809 is a highly integrated SoC for small-size and low bom cost solutions and reduced time-to-market.
