Power Section

The power supply of the system is 12V, which is disconnected when exceeding 19.7V. Software over voltage protection. The first way through MP2229/MP9189 DCDC buck pressure to 5.2V, then divided into three ways, one is through the over current protection IC SC7002 output 5V 1.5a.The second way is through LDO buck to 3.3V power supply N9013, 5V buck to 3.3v power supply MCU.
The second circuit directly supplies power to the two-circuit full-bridge rectifying circuit through MP2229/MP9189 voltage regulation. The third circuit directly supplies power to the two-channel full-bridge rectifying circuit through MP2229/ MP9189 voltage regulation. Route 4 supplies power to MP2229/MP9189.Provides PD output energy, communicates with external PD devices through PD protocol chip, and the maximum output power is 18W.

Wireless charging Section

1. The MCU output frequency 112kHz-147kHz. The waveform is loaded into the LC circuit by FS230DB to make the L coil emit a vibrating electromagnetic wave.
2. if there is a receiver in this range, the coil of the receiver receives electromagnetic waves and converts them into electric energy to make the receiving chip work. After the chip works, it sends packets of data, which are transmitted back to the transmitting end in the form of electromagnetic waves through the electromagnetic induction principle between the two coils.
3. the transmitter coil receives the packet, detects the current or voltage, and sends the communication code to the SCM for analysis through filtering and shaping, LM324 amplification and other processing. The SCM analyzes the communication code and makes corresponding actions according to the code, such as shaking hands, identifying, configuring, transmitting energy, monitoring and regulating energy, etc.
4. Coil AB is A double coil, which can only work one coil at the same time. Coil C is A single coil, which can work alone or with coil A at the same time. When coil B works, coil A &C does not work

Operation instruction

A. Connect the AC ADAPTOR DC connector to the charging board
B. Insert the AC end of the ADAPTOR into the AC socket
C. During power-on, the three indicators on the panel charge will turn off at the same time
and then turn off to indicate that the power-on self-test is complete.
D. Place the mobile phone to be charged in the middle of the leather surface area of the tablet.
E. If the indicator is on, it indicates that the battery is being charged.
F. When the mobile phone shows that charging is complete, remove the mobile phone and
turn off the power supply of the charging plate.
G. If you want to use USB PORT A or TYPE C, connect the charging board to the device using the corresponding cable.
