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

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 device operates over a wide supply range and

has low-power consumption. The TUSB320 device

is available in industrial and commercial temperature

ranges.
