3 Description

The TUSB320LA and TUSB320HA devices, hereafter

called TUSB320 unless otherwise noted, are Texas

Instrument's third generation Type-C configuration

channel logic and port controller. 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 them ideal for any application.

The

TUSB320

devices

have

an

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 depending on the

role detected. VBUS detection is 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 TUSB320LA and active high enable called

TUSB320HA. The TUSB320 family of devices are

available in industrial temperature ranges.
