IP6808_NF

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, it 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. It terminate power transfer when RX device is fully charged. Integrate full-bridge driver, includes voltage and current two-way ASK demodulation module, and input overvoltage/current protection and FOD module. It is a highly integrated SoC for small-size and low bom cost solutions and reduced time-to-market.
