  • Hi Wing,

    Thank you for designing with our products.  I took a look of your schematic and compared with our Datasheet pin assignment, I found your schematic's IC pin out is different from the datasheet, and it may explain why you see shorts.  See below.  

    Please correct the pin out errors. 

    Best Regards,

    Youhao
