IP6809 is a wireless charging transmitter control SoC chip, compatible with the latest WPC Qi v1.2.4 standard, support 3-coil wireless charging applications, support A28 coil, MP-A8 coil, support customer coil customized solutions, support 5W, Apple 7.5W, Samsung 10W, 15W charging. The IP6809 detects the wireless receiver by analog ping and establishes communication with the receiver to begin power transmission. IP6809 determines the position of the receiver by switching different working coils to perform analog ping and detect signal strength, and selects the coil with the strongest signal to perform charging action. The IP6809 decodes the communication packets sent from the receiver and then uses the PID algorithm to change the oscillation frequency to adjust the output power on the coil. Once the battery on the receiver is fully charged, the IP6809 terminates the power transmission.
    On-chip integrated full bridge drive circuit and voltage & current two ASK communication demodulation module, high integration, reduce the solution size and BOM cost.
