Part Number: BQ27542EVM
Other Parts Discussed in Thread: GPCCHEM

Tool/software:

Dear TI,

I have two questions and would appreciate your support in clarifying the following points:

Based on the data provided in the attached link, could you help analyze why the battery did not enter RELAX mode during the last five to six hours of idle time?

docs.google.com/.../edit
Is there a specific voltage range in which the battery does not update DOD0?
If the FLAG shows 0x003C, the battery should not have entered RELAX mode. In this case, will DOD0 still be updated?

Thank you in advance for your assistance.

Best regards,
Leo

Hello,

Would it be possible to send the google file in excel since we can't view google drive files. Also in the meantime could you attached the GPCCHEM calculator report you used to select your chemID as well.

Thank you,
Alan

Hello Leo,

Sounds good we will move to the new trend and have the question re-assigned to the battery gauge expert for this product.

Thank you,
Alan
