Overview

This addapter converts a USB standard host type-A port to Type-C DFP (downstream-facing port) with support for default, 1.5 A and 3.0A VBUS current levels. The TUSB2522 simplifies the design by integrating 2:1 USB 3.1 (up to 10 Gbps) mux with a DFP controller to monitor the Type-C configuration channel (CC) pins to determine plug orientation for mux selection and device attachment for controlling VCONN and VBUS power switches.

Features

Plug and Play design
The Reference Design operates off of the 5-V VBUS input from the legacy Type A USB connection
The Reference Design can provide VCONN over a CC pin based upon Type C plug orientation and Ra detection
DIP switch is provided to configure CC for different Type C current mode operations
