BQ76952: BQ76952电压采样问题:1. 电芯设置零伏读出值为65533 2. 电芯设置5.3伏,读出值200毫伏 。 voltage sample problem

Part Number: BQ76952

我遇到这样2个问题,帮忙分析下原因。

 1.  当测试电芯电压的输入范围时,发现当电压输入的电压为,比如VC1 与VC0之间为0伏时, 电压值读出可能出现很大的值 65533

2. 当VC1与VC0之间为5.3伏或者更大时,读出电压为200毫伏左右。但是5.1伏的时候能读出5.1伏、小于5伏的时候,读出也是正确的。

I  have two problem as following:

 1. when  the voltage between  vc1 and  vc0  is 0 , CELL1VOLTAGE   is  65533

 2. wen  the voltage beween vc1 and vc0 is more than 5100  mv  such as  5300 mv, CELL1VOLTAGE is 200 mv.   But  voltage low than 5100, CELL1VOLTAGE  is right
