Infineon Technologies HX3™ USB 3.0 Hub Controllers

Infineon Technologies HX3™ USB 3.0 Hub Controllers offer advanced charging capabilities, featuring eight downstream ports for enhanced connectivity and flexible design. These highly-interoperable Infineon EZ-USB™ hub controllers offer a feature set with robust interoperability, extensive charging support, and full configurability. HX3 devices are ideal for use in docking stations, monitors, Ultrabook™ devices, digital TVs, set-top boxes, printers, and servers. The versatile HX3 USB 3.0 hub controller offers a Ghost Charging™ feature for charging devices without a host, and it also supports the USB-IF Battery Charging v1.2 specification and charging of Apple devices. HX3 is also the first SuperSpeed USB (USB 3.0) hub controller to offer an Accessory Charger Adapter Dock (ACA-Dock) feature, which enables upstream charging for portable devices with a USB On-The-Go (OTG) host.
