USB EZ-PD Type-C

[JoLu_3455101]

Unlike CCG3, the CCG3PA doesn't have an assigned pin to supply VDDIO. I can only find one instance of "VDDIO" in the CCG3PA datasheet and it didn't specify. My questions are:

1. What determines or what is the VDDIO voltage? My input power comes from either VBUS_IN=20V or VDDD=5V.

2. For my GPIOs configured as outputs, is the high-level voltage same as VDDIO? If not, what is it?

Thanks,

Jonathan

Hi Jonathan,

1) The VDDIO supply is internally connected to VDDD. Thus if your input power is VDDD = 5V, VDDIO = 5V. If your input power is VBUS_IN, VDDIO = 3.3V; See page 6 of CCG3PA datasheet.

2) Yes, GPIO output high state will be at voltage level of VDDIO.
