    Sunflower is the UCD7138.  It's a gate driver with adaptive dead time adjustment.  It works with digital hardware in all the UCD3138 family A generation parts to optimize dead times in some topologies.  Search for UCD7138, and you will find the information.

    Thanks you for confirmation, that what i guessed, because the code is different only at DTC : )

    by the way, 

    Is there any document to explain about the details of the code [LLCHBFirmware-1.2].

    that would save a lot of my time on study.

    Xiaofeng, if you send me a friend request, I can send you a link to an old unpublished document we have.  It's not up to date, but I believe it will be helpful.  Sorry I missed your request.  For some reason I missed some notifications.
