USB Hub Controller IC subcategories
Infineon offers a wide portfolio of hub controllers supporting USB 480/12/1.5 Mbps, 5 Gbps and 10 Gbps (formerly called USB 2.0 hub and USB 3.0 hub) with robust backward interoperability with legacy USB speeds.
The USB 10 Gbps EZ-USB™ HX3PD hub controller provide advanced USB-PD and battery charging capabilities, featuring up to eight downstream ports for full configurability and flexible design.
The versatile EZ-USB™ HX3 is a USB-IF compliant USB 5 Gbps hub controller which allows the charging of devices without a host (ghost charge) and enables upstream charging for portable devices with a USB on-the-go (OTG) host (ACA-dock feature). EZ-USB™ HX3 also includes automotive-grade products.
EZ-USB™ HX2LP and HX2VL are highly integrated USB 2.0 480/12/1.5 Mbps 2- or 4-ports hub controllers.
Infineon EZ-USB™ family of hub controller ICs integrates many of the external passive components, such as pull-up and pull-down resistors, reducing the overall bill of materials (BOM) required to implement a hub design.
