IP6805U
IP6805U is a wireless charging transmitter control SoC chip that is compatible with the latest WPC Qi v1.2.4 standard, supports A11 or A11a coils, and supports 5W charging. The IP6805U detects the wireless receiver through analog ping and establishes communication with the receiver to begin power transmission. The IP6805U 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 IP6805U terminates the power transmission.
IP6805U chip integrated full bridge drive circuit and full bridge power MOS, voltage and current two ASK communication demodulation module; High solution integration can significantly reduce solution size and BOM cost.
