Texas Instruments TUSB322I USB Type-C™ Configuration Control

Texas Instruments TUSB322I USB Type-C™ Configuration Channel Logic and Port Control enable USB Type-C ports with the configuration channel (CC) logic needed for Type-C ecosystems. The TUSB322I uses the CC pins to determine port attach and detach, cable orientation, role detection, and port control for Type-C current mode. The device 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 TUSB322I alternates configuration as a DFP or UFP according to the Type-C specifications.
