Hi Team,

BQ25898 or BQ25890 had REF01 to configure the VBUS voltage to 9V/12V, however, BQ25895 doesn't have this REG to configure.

Could you advise how to configure BQ25895 to 9V?

Thanks.

Johnson,

Are you referring to RGE02[3] HVDCP_EN? BQ25895 has the same register bit with default enabled. If the adapter is a HVDCP, the handsahking starts when power up.

Johnson,

BQ25890H and BQ25898/898D has the the EN_12V bit that can control the enable/disable(default) handshaking for 12V.
