TUSB321 USB Type-C Channel Logic & Port Control
Texas Instruments TUSB321 USB Type-C™ Configuration Channel Logic & Port Control enables USB Type-C ports with the configuration channel (CC) logic needed for Type-C ecosystems. The TUSB321 device uses the CC pins to determine port attach and detach, cable orientation, role detection, and port control for Type-C current mode. The TUSB321 can be configured as a downstream facing port (DFP), upstream facing port (UFP) or a dual role port (DRP). This makes it ideal for any application. The TUSB321 device from Texas Instruments alternates configuration as a DFP or UFP according to the Type-C Specifications.
