Hello

Question that can we use TPS25750+BQ25730 for an integrated battery charging?

Thanks

    The TPS25750 will manage most of the functions necessary for battery charging using the BQ25730.

    You will need to add either a battery gas gage or a system MCU to manage charger termination for the BQ25730 because the TPS25750 does not manage this feature for the charger.

    If you are able to use the BQ25792 or BQ25792 in your system, charge termination is supported for these 2 chargers.

    1:The TPS25750 will manage most of the functions necessary for battery charging using the BQ25730

    Can we select BQ25731 at battery charger configuration when we create firmware for  TPS25750 +BQ25730 ?

    2:Could you describe what is charger termination function?

    1.  The BQ25750 and BQ25731 are identical as far as the TPS25750 is concerned, so the same configuration can be used.

    2.  Charge termination occurs when the battery has be fully charged and the charger needs to stop providing the same level of current.  You can get a better description for the BQ team and it is covered in the Datasheet of the BQ25730.
