Hi TI expert

I will use the BQ24133 for design charger of the 3S3P battery pack.

Adapter Voltage = 15V

Battery Voltage = 12.6V (When Full)

if reference of the datasheet design

What the system voltage is adapter or battery when adapter plug-in?

Is 15V? or 12.6V? or other?

Best regards,

    Hello,

    The below excerpt is from the datasheet.

    "When the qualified adapter is present, the system is directly connected to the adapter. Otherwise, the system is connected to the battery. In addition, the power path prevents battery from boosting back to the input."

    Thanks,

    Mike Emanuel
