Other Parts Discussed in Thread: BQ24610,
This is Hung and please help me to solve my HW issue.
In my schematic, I use BQ24610 and BQ27220 in the same time.
BQ24610 is to charge battery and switch the system power source which supplied from adapter or battery.
Because OS need to know how much battery power capacity remained, so I use BQ27220 to let SOC/CPU know such battery power capacity information by I2C bus.
However, BQ24610 behavior is wrong, it cannot switch power source and cannot charge my battery.
After do remove BQ27220 related schematic experiment, BQ24610 behavior is normal, it can switch power source and charge my battery.
Above is my encountered problem so far, the bellowing picture is my power delivery and attached file are BQ27220(P37-BATT RECORDER.PDF) and BQ24610(P25 – SYSTEM_PWR.PDF) schematic.
Please help to bellowing items
- Is the BQ27220 schematic correct?
- In the bellowing power delivery, Is BQ27220 suitable??
- Can BQ27220 and BQ24610 use in the same time??
Or any suggestion/experiment about this problem.
