Overview
The TUSB320LAIRWBR is a Type-C configuration channel logic and port controller produced by Texas Instruments. It is part of the TUSB320 family, which represents the third generation of Type-C configuration channel logic and port controllers. These devices are designed to determine port attach and detach, cable orientation, role detection, and port control for Type-C current mode using the CC pins. The TUSB320LAIRWBR 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 device operates over a wide supply voltage range of 2.7 V to 5 V and has low current consumption, with an industrial temperature range of –40 to 85°C.
