Dear ADIer

I have a problem on SOC error and No battery detection in ADP5350 .

My experiment is done on EVM

 

 

1. Fuel Gauge / Level
1)  The battery level jumble suddenly while charging. For example, it was about 12%, but suddenly it was 95%.

2) The battery voltage value calculated by reading from 0x22, 0x23 is close to zero.

 

2. Fully discharged battery can not be charged
1) If you connect a fully discharged battery,
    CHARGER_STATUS [2: 0] is 111 (battery detection) and BATTERY_STATUS [2: 0] is 001 (No battery).
2) In this case, after charging a little with other chargers, you can charge the battery by connecting the charger.

 

Thanks
