3 Description

The TUSB322I device enables USB Type-C ports

with the configuration channel (CC) logic required for

Type-C ecosystems. The TUSB322I device uses the

CC pins to determine port attach and detach, cable

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

current

mode.

The

TUSB322I

device

can

be

configured as a downstream facing port (DFP),

upstream facing port (UFP), or a dual role port (DRP),

making

the

TUSB322I

device

ideal

for

any

application.

The TUSB322I device alternates configuration as a

DFP or UFP according to the Type-C Specifications.

The CC logic block monitors the CC1 and CC2 pins

for pullup or pulldown resistances to determine when

a USB port has been attached, the orientation of the

cable, and the role detected. The CC logic detects

the Type-C current mode as default, medium, or high

depending on the role detected. VBUS detection is

implemented to determine a successful attach in UFP

and DRP modes. The TUSB322I will supply VCONN

when an active cable is detected.

The device operates over a wide supply range and

has low-power consumption. The TUSB322I device is

available in industrial temperature ranges.
