Other Parts Discussed in Thread: BQ27220
We found the battery cannot be charged through BQ24250, so I read the register 0 to get the status.
The status is 0x34 means the STAT is Fault.
No matter I unplug or plug the battery, the value of register 0 always 0x34.
Therefore, it is not impacted by battery.
I've attached the partial schematic, please check.
Could you guide us how to resolve it? Thanks.
3.8V and 300mA.
