Part Number: BQ25792

Hi

The customer design with BQ25792, connect the adapter (input voltage 12V), disconnect the load, and only charge the battery. When the battery is full, STAT output high. At this time, the adapter is re-plugged, the stat pin output is unstable and the charging indication status is unclear.

Why is the output status of the STAT pin unstable?

The schematic as below:

Please help check it.

Thanks
