BQ27532-G1: I2C of bq27532 issue

Part Number: BQ27532-G1
Other Parts Discussed in Thread: BQ24295, BQSTUDIO


There is an issue about the I2C of bq27532.

1.Power from battery => Sometimes, MCU can not read/write bq27532 via I2C. I2C of BQ24295 always works fine.

2.Unplug USB port =>  MCU can not read/write bq27532 via I2C.

3.Power from USB port (battery connected)=> no this issue. 

Could you please help to check the schematic if any issue about this ?
