Apple magnetic wireless charging solution based on Ingenic IP6808

Apple 12 wireless charging pop-up window 15W solution (Ingenics first-level agent - Kefaxin makes an exception to share)
Overview
IP6808 is a wireless charging transmitter control SoC chip, compatible with the latest WPC Qi v1.2.4 standard, supports A11 coil, supports 5W, Apple 7.5W, Samsung 10W, EPP 15W charging. IP6808 detects the wireless receiver through analog ping and establishes communication with the receiver, then starts power transmission. IP6808 decodes the communication data packet 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, IP6808 terminates power transmission.
The chip integrates a full-bridge drive circuit and a voltage & current two-way ASK communication demodulation module, with high integration, reducing the solution size and BOM cost.
