Backward Compatible with USB Type-C

Type-C ecosystems. The TUSB322I device uses the

Specification 1.0

CC pins to determine port attach and detach, cable

•

Supports Up to 3 A of Current Advertisement and

orientation, role detection, and port control for Type-C

current

mode.

The

TUSB322I

device

can

be

application.

–

Dual Role Port – DRP

The TUSB322I device alternates configuration as a

DFP or UFP according to the Type-C Specifications.
