    Hi Sasaki-san,

    Unfortunately there isn't anything additional to what is in the datasheet.  Voltage measurement accuracy is sufficient for accurate gauging.  Current measurement accuracy depends on various factors including the sense resistor.  Temperature measurement accuracy depends on the thermistor and other factors, as well.  The best option is to characterize the accuracy in your system with your design and components.

    Hi,

     

    May I know what is the range of AverageCurrent BQ27541 can measure ? From datasheet, it will return a signed integer, and unit is mA.  Will that be  −32,768mA to 32,767mA ?

    CM.
