  • RE: BQ25898: About CHRG_FAULT register

    Resolved
    Hi Yusuke, Please see my comments below. 1) Yes CHRG_FAULT will return to 00 when VBUS returns to normal, but the customer will need to read REG0C twice in a row to see current status. Section 9.2.9.2 of the BQ25898 datasheet on page 27 explains how REG0C…
