Hi team,

    Hi Alice,

    Yes, when configured correctly, the BQ25798 is capable of charging an 8.9V battery with an input of 9V. Refer to Table 9-2 in Section 9.3.2 of the datasheet for default settings and associated VREG ranges that can be controlled by the host device.

    Best Regards,

    Austin
