3 Description

The TUSB320 device enables USB Type-C ports

with the configuration channel (CC) logic needed

for Type-C ecosystems. The TUSB320 device uses

the CC pins to determine port attach and detach,

cable orientation, role detection, and port control

for Type-C current mode. The TUSB320 device 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 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

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 device operates over a wide supply range and

has low-power consumption. The TUSB320 device

is available in industrial and commercial temperature

ranges.
