TUSB321AIRWBR USB Interface Controller 12-X2QFN
The TUSB321AIRWBR is a USB Type-C Configuration Channel (CC) Logic and Port Controller from Texas Instruments, designed to implement the essential CC logic required for USB Type-C ecosystems. This device uses the CC pins to detect port attachment, cable orientation, and role (Source, Sink, or Dual-Role), and controls the Type-C current mode (Default, Medium, or High up to 3A). It operates from a 4.5V to 5.5V supply, features low current consumption, and is rated for the industrial temperature range of -40°C to 85°C. Housed in a compact 12-pin X2QFN (RWB) package, it supports VCONN for active cables and provides external switch control for cable detection and direction.
The TUSB321AIRWBR is engineered for modern devices requiring reliable USB Type-C connectivity and power negotiation. Its primary applications include mobile phones, tablets, laptops, and a wide range of USB peripherals. It is also essential in docks, adapters, power banks, and any embedded system where a configurable USB Type-C port with role detection and up to 3A current capability is needed.
Alternative Type-C CC controllers
● TUSB320HAI (Texas Instruments): A third-generation USB Type-C CC controller from TI with I2C or GPIO control, supporting Try.SRC/SNK functionality and a wider 2.7V to 5V supply range.
● TUSB321 (Texas Instruments): A similar USB Type-C CC logic and port controller, functionally comparable to the TUSB321AI but potentially an earlier version or with minor specification differences.
● TUSB322I (Texas Instruments): A member of TI's GPIO-series CC controllers designed with an external DIR pin for USB 3.x SuperSpeed MUX control, ideal for high-speed data applications.
● FUSB302B (ON Semiconductor): A programmable USB Type-C controller with integrated PD PHY, supporting the USB Power Delivery protocol for advanced power negotiation beyond basic Type-C.
