We have some questions on the calibration of BQ34Z100-G1.
1. We found that the CC offset value cannot go to zero after calibration complete.Does this current from BQ34z100-G1 must be exactly ‘0’ without tolerance when actual current is 0? How that’s possible? Thermal and age can also affect this value, is it true?
2. What parameters will be affect if cannot calibrate to zero current?
3. We found some units report 0 before calibration, but can be 0 after, seems there are bugs in algorithm, any comment?
4. Can TI share us the procedure, theory and algorithm in details for this calibration?
