15W Wireless Charger (TX): IP6821

1. The IP6821 is a highly integrated wireless charging transmitter control chip compliant with the WPC qi standard. Internally, it integrates an H-bridge driver module, an ASK communication demodulation module, and the adapter fast charging sink protocol, among other essential wireless charging resources.
2. It supports foreign object detection; if a metal object is detected in the coil, operation will stop to prevent overheating.
3. The WX15W-6821-0 represents the most cost-effective version of the IP6821 solution. It supports

. Note:
1. When the TX coil deviates significantly from the resonant point of the RX coil of the device being charged, the wireless charging efficiency will decrease, which is normal.
After the charging efficiency decreases, the temperature of the MOS will rise. Therefore, the wireless charging coil needs to be attached and fixed to the PCB board so that the PCB board can dissipate heat through the coil. Furthermore, the NTC resistor can effectively collect the overall temperature of the board and coil.
