TUSB319-Q1 USB Type-C DFP Port Controller
1 Features
3 Description
•
•
The TUSB319-Q1 is a USB Type-C Downstream
Facing Port (DFP) controller. The TUSB319-Q1
monitors the USB Type-C Configuration Channel
(CC) lines to determine when an USB device is
attached. If an Upstream Facing Port (UFP) device is
attached, the TUSB319-Q1 drives an open drain
output ID that can be used in the system to apply
VBUS power. The device also communicates the
selectable VBUS current sourcing capability to the
UFP via the CC lines.

7 Detailed Description
7.1 Overview
The USB Type-C ecosystem operates around a small form factor connector and cable that is flippable and
reversible. Because of the nature of the connector, a scheme is needed to determine the connector orientation.
Additional schemes are needed to determine when a USB port is attached and the acting role of the USB port
(DFP, UFP), as well as to communicate Type-C current capabilities. These schemes are implemented over the
CC pins according to the USB Type-C specifications. The TUSB319-Q1 device provides Configuration Channel
(CC) logic for determining USB port attach and detach, cable orientation, and Type-C current mode for DFP
applications.
7.1.1 Cables, Adapters, and Direct Connect Devices
Type-C Specifications defines several cables, plugs and receptacles to be used to attach ports. The TUSB319Q1 device supports all cables, receptacles, and plugs. The device does not support e-marking.
7.1.1.1 USB Type-C Receptacles and Plugs
Below is list of Type-C receptacles and plugs supported by the device:
• USB Type-C receptacle for USB2.0 and USB3.1 and full-featured platforms and devices
• USB full-featured Type-C plug
• USB2.0 Type-C plug
7.1.1.2 USB Type-C Cables
Below is a list of Type-C cables types supported by the device:
• USB full-featured Type-C cable with USB3.1 full-featured plug
• USB2.0 Type-C cable with USB2.0 plug
• Captive cable with either a USB full-featured plug or USB2.0 plug

7.3.1 Downstream Facing Port (DFP) - Source
The TUSB319-Q1 is a DFP device; it presents the appropriate Rp resistors on both CC pins, based on the state
of the CURRENT_MODE pin to advertise the desired current level (USB-standard, 1.5 A and 3 A).
The TUSB319-Q1 can operate with older USB Type-C 1.0 devices except for a USB Type-C 1.0 DRP device.
This limitation is a result of backwards compatibility problem between USB Type-C 1.1 DFP and a USB Type-C
1.0 DRP.

7.3.2 Type-C Current Mode
The TUSB319-Q1 device supports both advertising Type-C current by means of the CURRENT_MODE pin,
which allows the CC controller to advertise 500 mA (for USB2.0) or 900 mA (for USB3.1) if CURRENT_MODE
pin is left unconnected or pulled to GND. If a higher level of current is required, the CURRENT_MODE can be
pulled up to VDD through a 500-kΩ resistor to advertise medium current at 1.5 A or pulled up to VDD through a
10-kΩ resistor to advertise high current at 3 A. Table 2 lists the Type-C current advertisements and detection.

Medium - 1.5 A
CURRENT_MODE = M
High - 3 A
CURRENT_MODE = H
7.3.3 VBUS Detection
The TUSB319-Q1 device supports VBUS detection according to the Type-C Specification. The system VBUS
voltage must be routed through a 900-kΩ resistor to the VBUS_DET pin on the TUSB319-Q1. When voltage on
VBUS_DET pin is below the VBUS(THR) and Rd is detected on either CC1 or CC2, the TUSB319 assumes system
VBUS is at vSafe0V (VBUS < 800 mV) and will assert ID low.
If VBUS_DET pin is left unconnected system needs to ensure that the VBUS level is below vSafe0V before
VBUS is enabled.
7.3.4 Cable Orientation
The TUSB319-Q1 detects the cable orientation by monitoring the voltage on the CC pins. When a voltage level
within the proper threshold is detected on CC1, the DIR pin is pulled low. When a voltage level within the proper
threshold is detected on CC2, the DIR is pulled high. The DIR pin is an open drain output.
7.4 Device Functional Modes
The TUSB319-Q1 device has two functional modes. Table 3 lists these modes:

7.4.1 Unattached Mode
Unattached mode is the primary mode of operation for the TUSB319-Q1 device, because a USB port can be
unattached for a lengthy period of time. In unattached mode, all IOs are operational. After the TUSB319-Q1
device is powered up, the part enters unattached mode until a successful attach has been determined.
7.4.2 Active Mode
Active mode is defined as the port being attached. When in active mode, the TUSB319-Q1 device communicates
to the system that the USB port is attached. This happens through the ID pin. The TUSB319-Q1 device exits
active mode when the cable is unplugged.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The TUSB319-Q1 device is a Type-C configuration channel logic and port controller. The TUSB319-Q1 device
can detect when a Type-C device is attached, what type of device is attached, the orientation of the cable, and
power capabilities, this power capabilities are sourcing only since the TUSB319-Q1 device can be used in a
source application (DFP) only.

Typical Application (continued)
8.2.1.1 Design Requirements
For this design example, use the parameters listed in Table 4:

DESIGN PARAMETER
VALUE
VDD (3.8 V to 5.5 V)
5V
Advertised Type-C Current (Default, 1.5 A, 3 A)
3A
8.2.1.2 Detailed Design Procedure
The TUSB319-Q1 device supports a VDD in the range of 3.8 V to 5.5 V. In this particular case, VDD is set to 5 V.
A 100-nF capacitor is placed near VDD.
The TUSB319-Q1 current advertisement is determined by the state of the CURRENT_MODE pin. In this
particular example, 3 A advertisement is desired so the CURRENT_MODE pin is pulled high to VDD through 10kΩ resistor.
The VBUS_DET pin must be connected through a 900-kΩ resistor to VBUS on the Type-C that is connected. This
large resistor is required to protect the TUSB319-Q1 device from large VBUS voltage that is possible in present
day systems. This resistor along with internal pulldown keeps the voltage observed by the TUSB319-Q1 device
in the recommended range.
The USB2 specification requires the bulk capacitance on VBUS of at least 120 µF. In this particular case, a 150µF capacitor was chosen.
TUSB319-Q1 does not provide VBUS discharge and requires an external solution either through switched
resistor pull-down as shown in Figure 2 or elsewhere in the system.

8.3 Initialization Set Up
The general power-up sequence for the TUSB319-Q1 device is as follows:
1. System is powered off (device has no VDD).
2. VDD ramps – POR circuit.
3. The TUSB319-Q1 device enters unattached mode.
4. The TUSB319-Q1 device monitors the CC pins.
5. The TUSB319-Q1 device enters active mode when attach has been successfully detected.
9 Power Supply Recommendations
The TUSB319-Q1 device has a wide power supply range from 3.8 V to 5.5 V.
10 Layout
10.1 Layout Guidelines
1. An extra trace (or stub) is created when connecting between more than two points. A trace connecting pin A6
to pin B6 will create a stub because the trace also has to go to the USB Host. Ensure that:
– A stub created by short on pin A6 (DP) and pin B6 (DP) at Type-C receptacle does not exceed 3.5 mm.
– A stub created by short on pin A7 (DM) and pin B7 (DM) at Type-C receptacle does not exceed 3.5 mm.
2. A 100-nF capacitor should be placed as close as possible to the VDD pin.
