3 Description

The TUSB320LI and TUSB320HI devices (remainder

of this document called TUSB320 unless otherwise

noted)

enables

USB

Type-C

ports

with

the

configuration channel (CC) logic needed for Type-C

ecosystems. The TUSB320 devices use the CC pins

to

determine

port

attach

and

detach,

cable

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

current

mode.

The

TUSB320

devices

can

be

configured as a downstream facing port (DFP),

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

making it ideal for any application.

The TUSB320 devices alternate 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

implemented to determine a successful attach in UFP

and DRP modes.

The devices operate over a wide supply range and

have low-power consumption. The TUSB320 is

available in two versions of enable: Active low enable

called TUSB320LI and active high enable called

TUSB320HI. The TUSB320 family of devices are

available in industrial temperature ranges.
