充电盒主PCBA另一侧的电路图显示了MCU相关电路。

The SY8801 chip specially designed by Siyuan Semiconductor for the TWS headset charging case is based on a design that ensures safe and high-reliability performance (supports 28V input withstand voltage, built-in full-featured charging and discharging overvoltage, overcurrent, overtemperature, short-circuit protection, etc.), and also integrates I2C communication functions and internal communication isolation functions. Through the I2C interface, the system's MCU can read and configure the internal functions of the power supply and the parameters of battery charge and discharge management, and easily implement functions such as NTC protection, segmented battery current adjustment, TWS headset entry and exit detection, automatic power output opening, etc.

思源SY8801集成的内部通信隔离模块极大地优化了智能TWS充电盒的功能设计，无需复杂的外部电路。MCU可通过连接控制SY8801，不仅可以为耳机充电，还可以通过连接耳机的电源的POGO引脚进行通信和数据传输，包括上传充电盒的电池容量、清除充电盒内耳机的配对信息、恢复出厂设置以及升级耳机软件。
