Compiler/BQ78350-R1: BQ76930+BQ78350-R1

Part Number: BQ78350-R1

Tool/software: TI C/C++ Compiler

Dear :

       这里有一个新的问题关于BQ7690+BQ78.50-R1 的板子，一个7串的板子，总共做了25块板子，有连续8块都是出现第二串和第三串电压异常。我检查采样部分，如下图的红色框所示，没有发现异常；请帮忙给个建议，可能是哪个地方有问题，导致出现一样的问题。

    Hi,

    The schematic looks okay, but the voltage readings seem as if there is an open connection on one of the cells or on one of the VCx pins of the device. Table 25 in the datasheet shows the recommended connections for reducing the cell count (for configurations with less than 10 cells). Make sure to follow these guidelines.

    Best regards,

    Matt
