大家上午好!
BQ76930规格书上描述的ADC测量范围值,电芯电压的范围是2至5V,请问当实际电芯的电压值小于2V(如1.8V)时,BQ76930会上传一个什么样的电压值给MCU呢?

HiThe bq76930 ADC will continue to convert the voltage on the inputs. The error when corrected with the stored gain and offset will increase, see figure 6-2 of the data sheet. When the voltage drops below UVMINQUAL the cell will no longer be considered UV, this is for automatic configuration.

还是电压值,但可能精度不在正常电压范围的要差些。
