Part Number: BQ25883

Hi Sir,

My customer has a question about the VBUS status.

When the BQ25883 w/o a battery now, and plug-in a DCP adapter, they found the VBUS status shown "USB SDP", is it correct? why?

    Hello Henry,

    We have no reported issues of SDP detection falsely with this device, it is most likely an issue with the adapter being connected and not the charger. Please share the D+/D- waveform during detection.

    Sincerely,

    Wyatt Keller
