The TUSB320 from Texas Instruments (TI) 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.
