Part Number: BQ79731Q1EVM-060
BQ79731在做电压采集的时候使用的是VF1引脚,当高压接插件没有接的时候,VF1引脚可以采到40mV的电压,请问这是什么原因呢?电路如下图

您好,This could be leakage from the MOSFET inside of the V_PACK+ circuit. I would try and do some probing to see if you can find any unwanted voltage/current and trace it to its source. Also review the datasheet of the MOSFET to see if there are any clue in there.
