BQ25703A: How to get charging battery full state?

Part Number: BQ25703A

Dear All

      When the battery charged full, how can the host get the state ?

  • 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
