采用76940+78350的方案,疑问是不是配置78350的参数就可以了,76940只是当一个电压电流采集的作用。

在用户手册中,BQ78350具备充电算法,如
The bq78350-R1 charge control features include:
• Provides a range of options to configure the charging algorithm and its actions based on the application
requirements
• Reports the appropriate charging current needed for constant current charging, and the appropriate charging
voltage needed for constant voltage charging
• Supports pre-charging/0-volt charging
• Supports charge inhibit and charge suspend if battery pack temperature is out of temperature range
请问芯片是如何控制的,是通过BQ76940的DSG、CHG控制充电电流、电压吗?但是BQ76940寄存器的更新率大约为250ms,这么低的更新率如何控制FET开关,以达到控制电压、电流的目的
