Cxlb73171 is a SoC chip for wireless charging transmitter control, which is compatible with the latest standard of WPC Qi v1.2.4, supports 3-coil wireless charging application

Cxlb73171 is a SoC chip for wireless charging transmitter control, which is compatible with the latest standard of WPC Qi v1.2.4, supports 3-coil wireless charging application, supports A28 coil, mp-a8 coil, supports customized coil solutions, supports 5W, apple 7.5W, Samsung 10W, 15W charging. The cxlb73171 detects the wireless receiver through the analog Ping, and establishes the communication with the receiver, then starts the power transmission. Cxlb73171 determines the position of the receiver by switching different working coils to perform the analog Ping and detect the signal strength, and selects the coil with the strongest signal to perform the charging action. The cxlb73171 decodes the communication packets sent from the receiver, and then uses PID algorithm to change the oscillation frequency to adjust the output power on the coil. The cxlb73171 terminates power transmission once the battery on the receiver is fully charged.

       CXLB73171是一款无线充电发射端控制SoC芯片,兼容WPC Qi v1.2.4最新标准,支持3线圈无线充电应用,支持A28线圈、MP-A8线圈,支持客户线圈定制方案,支持5W、苹果7.5W、三星10W、15W充电。CXLB73171通过analog ping检测到无线接收器,并建立与接收端之间的通信,则开始功率传输。CXLB73171通过切换不同的工作线圈执行analog ping并检测信号强度的方式确定接收机摆放位置,并选择信号最强的线圈执行充电动作。CXLB73171解码从接收器发送的通信数据包,然后用 PID算法来改变振荡频率从而调整线圈上的输出功率。一旦接收器上的电池充满电时,CXLB73171终止电力传输。 片内集成全桥驱动电路和电压&电流两路ASK通讯解调模块,集成度高,降低方案尺寸和BOM成本。
