Hi team,

My customer would like to check with us if BQ25600D D+/D- connected could be connected as below when use with Qualcomm platform(for data transfer), could you help comment?

If not, how should customer connect with Qualcomm AP?

    Will,

    D+/D- pins are used for USB input current limit detection when VBUS power is plugged in. During the charger input current limit detection process, the host must be able to HIZ D+/D- pins so that D+/D- pins are driven by the charger. If the host is unable to HIZ D+/D- pins, a USB switch is needed to isolate the D+/D- pins of the host and the charger.

    Thanks,

    Ning.
