BQ76952: BQ76952 voltage calibration

Part Number: BQ76952
Other Parts Discussed in Thread: BQSTUDIO

Dear Export,

I would like to know how the BQstudio performs voltage calibration since the calibration document here says we have to use two points

for voltage calibration but in the BQstudio we have to provide only one voltage for each voltage type. Do you only calibrate offset and for gain

calibration you use 0 volt as "another voltage"?

Thanks and regards,

Hello Andras,

I believe that BQStudio performs a one-point calibration. The calibration app note mentions (in Section 2.1 Calibration Accuracy) the different levels of calibration that you can perform, a two-point calibration will give you the best calibration accuracy and allow you to calibrate for offset too.

The following E2E thread may be useful and goes into more detail about this type of calibration:
