    Hi Ray,

    The difference between SDP1 and SDP2 is that SDP2 does not have a VBUS discharge if the mode switches to CDP. This is a desirable feature for Port Power Management, as described in the datasheet:

     

    SDP1 will have a VBUS discharge when it switches to any other mode.

    Thanks,

    Emma
