TUSB321RWBR Description

Short technical summary and product information.

The TUSB321RWBR is an integrated circuit from Texas Instruments designed for USB Type-C port control. It provides the necessary configuration channel (CC) logic for USB Type-C ecosystems, enabling port attach and detach detection, cable orientation, role detection, and port control for Type-C current modes.

 

This device supports USB Type-C Specification 1.1 and is backward compatible with Specification 1.0. It can advertise up to 3A of current through a dedicated Current Mode pin. The TUSB321RWBR can be configured as a Downstream Facing Port (DFP), Upstream Facing Port (UFP), or a Dual Role Port (DRP), making it versatile for various applications. The CC logic monitors CC1 and CC2 pins to determine port status, cable orientation, and detected role.

 

Packaged in a 12-X2QFN (1.6x1.6) surface mount package, the TUSB321RWBR operates within an ambient temperature range of 0°C to 70°C. It requires a supply voltage between 4.5V and 5.5V and consumes low current. The device supports Type-C current modes including Default, Medium, and High, along with VBUS detection and VCONN support for active cables.
