    VBUS, GND and SHIELD schematics

      Hi,

         

      The VBUS connection is a bit confusing. Specifically after reading the application note: AN1168 (Please compare this application note with the schematics). 

         

      How should I connect the VBUS to the CYUSB3014 if I only want to use the CYUSB3014 as a cell-power device only (No OTG application). Do I need to use 39K or 62K resistors (AN1168) along with the BLM21PG221SN1D (inductor)? I would appreciate it if you could also specify the whole path from the VBUS pin on the USB connector to the VBUS pin on the CYUSB3014.

         

      Thanks,
