Switch Switch: Complete the function of TX/RX (transmission/reception) signal multiplexing I2S/MCLK on the mobile phone;

Controller: Control and switch the connection mode of TX/RX signal according to the working scene;

High-speed physical serial bus USB-PHY; TX/RX for USB data transmission; detection pin CC completes insertion detection; D+/D- completes the charging handshake function.

Audio codec Audio codec: processing mic input signal;

Converter Adapter: When you need to charge while using audio peripherals, you need to use a converter; a double-sided plug Type-C plug is inserted into the terminal, and the charging and audio signals are respectively transferred to two socket receptacle .

If the handshake is successful, the OTG will be turned off. The charging Vbus will supply power to the audio peripherals and start charging at the same time. If the handshake fails, continue to play music.

C. When CC1/2 detects that the charging device is inserted, the charging handshake is performed through D+/D- (no switch control is required, it is directly connected to the Type-C interface), and after the handshake is successful, the charging voltage and current are configured for charging; monitoring CC1/2 Voltage, when the threshold (resistance parameter value) that triggers the simultaneous insertion of the earphone and the charger is detected, the controller controls the switch to switch to I2S/MCLK, and the audio signal is transmitted to the audio peripheral through I2S when the user plays music. The power of the audio peripherals is provided by the Vbus of the charger.

D. When CC1/2 detects that the charger and audio peripherals are plugged in at the same time (through the transfer interface, one to two), the charging handshake is performed through D+/D-; the audio signal is output to the audio peripheral through TX/RX , the power of the audio peripherals is provided by the Vbus of the charger.

Note: When the charger is unplugged while playing music, the music will be paused when the charger is detected to be unplugged, and the user will turn on the OTG to supply power to the audio peripherals when the user restarts to play music.

The audio peripherals may be devices such as speakers, which are not limited here.
