Part Number: BQ78350-R1A
Other Parts Discussed in Thread: BQ78350-R1, BQSTUDIO,

It seems that the register arrangement is slightly different between bqStudio and BQ78350-R1 Technical Reference. (See attached file)
Do you have the correct material?

Best regards,
Kagawa

    Hi Kagawa-san,

    It looks like you are using the BQ78350-R2 firmware based on the images from BQStudio. There were some changes to the register map in the R2 revision. Some of these changes are explained in this document: https://www.ti.com/lit/ug/sluubm6/sluubm6.pdf

    However, the document does not show all of the details. BQStudio is the best way to view the R2 register map. In the Data Memory tab, you can also see the register addresses. You need to select Window->Preferences->Show Advanced Views, and then it will also display the register addresses.

    The BQ78350-R1A TRM still is the best reference to explain the device operation, but it is important to refer to the differences document and BQStudio to update the register addresses in the application.

    Best regards,

    Matt
