Other Parts Discussed in Thread: BQ40Z50, BQ4050
Tool/software:
Dear
The occurrence of IFC batteries was discovered by the ODM manufacturer during the use of the batteries, which were shipped to the ODM manufacturer after the functional testing of the finished battery was OK and there were no issues,
Because our battery was shipped in shutdown mode and only used after ODM charging activation, we found that the battery had entered the IFC protection mechanism after charging activation;
Regarding the issue of battery power on sequence, do you need to confirm if this IC has a requirement for no power on sequence?
We found that during the production process, there is a certain probability that the chip will enter ROM mode if it is not powered on in sequence; Flash information is cleared;
And on the BQ4050 and BQ40Z50 chips, we will not encounter such problems.
