    Question for CYPD4255-96BZXI Vconn Current


      Display cannot work when using our USB3.1 TypeC active cable to connect display and NB which uses CYPD4255-96BZXI as USB interface IC.  It seems that this NB limits the current of Vconn at startup stage. If over current detected, it will shutdown the power of Vconn. The inrush current of our Active cable is about 400mA.


      Does CYPD4255-96BZXI  really limits the current of Vconn? If yes, what's the value of limitation current?
