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.

CC2 (1) | 1 | I/O | Type-C configuration channel signal 2 |
CURRENT_MODE | 2 | I | Advertise VBUS current. This 3-level input is used to control Type-C current advertisement. The pin can be dynamically set. L - Default Current is 500 mA for USB 2.0 and 900 mA for USB 3.1. Pull-down to GND or leave unconnected. M - Medium current is 1.5 A. Pull-up to TUSB319-Q1 VDD with 500-kΩ resistor. H - High current is 3 A. Pull-up to TUSB319-Q1 VDD with 10-kΩ resistor. |
VBUS_DET | 3 | I | 5-V to 28-V system VBUS input voltage. One 900-kΩ external resistor required between system VBUS and VBUS_DET pin. |
DIR | 4 | O | Type-C plug orientation. This open drain output indicates the detected plug orientation: Type-C plug position 2 (H); Type-C plug position 1 (L). |
ID (1) | 5 | O | Open drain output; asserted low when the CC pins detect device attachment. |
GND | 6 | G | Ground |
VDD | 7 | P | 3.8-V to 5-V power |
CC1 (1) | 8 | I/O | Type-C configuration channel signal 1 |
