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.
