Hi,
In general, for customer's system design they will use gauge to monitor battery status, whatever in charging mode or charge full.
But if you don't have gauge, I suggest you can use BQ25703A internal ADC to read back battery voltage (Reg0x2Ch) and charge current (Reg0x29h) data to judge battery is full or not.
Thank you and Regards
