Image of Texas Instruments' TUSB422 USB PD TCPCi Port Controller Texas Instruments' TUSB422 is a USB PD PHY that enables a USB Type-C port with the configuration channel (CC) logic needed for USB Type-C ecosystems. It integrates the physical layer of the USB BMC power delivery (PD) protocol to allow up to 100 W of power and support for alternate mode interfaces. An external microprocessor, containing USB Type-C port manager (TCPM), communicates with the TUSB422 through an I²C interface.

Under control of the TCPM, TUSB422 uses the CC pins to determine port attach/detach, cable orientation, role detection, and port control for USB Type-C current mode. The TUSB422 can be configured as DFP, UFP, or DRP, depending on the application. The TUSB422 implements V_BUS detection and discharge for the implementation of a compliant USB Type-C port.

The TUSB422 integrates a 2.5 W switch to provide V_CONN power for an active cable. The device also provides a V_CONN discharge function. The TUSB422 also supports USB Type-C optional features, such as audio and debug accessory.

The device operates over a wide supply range and has low power consumption. The TUSB422 is available in industrial temperature ranges.
