USB Hub Controllers Unterkategorien
Infineon offers a wide portfolio of hub controllers supporting USB 2.0 and USB 5 Gbps and USB 10 Gbps. The hub controllers provide advanced USB-PD and battery charging capabilities, featuring up to eight downstream ports for enhanced connectivity and flexible design.
EZ-USB™ HX3 and EZ-USB™ HX3PD devices are ideal for use in docking stations, monitors, notebook computers, digital TVs, set-top boxes, printers, and servers. The versatile EZ-USB™ HX3 USB 5 Gbps hub controller allows the charging of devices without a host (ghost charge) and Apple devices, supports the USB-IF Battery Charging specification (BC v1.2) and includes an Accessory Charger Adapter Dock (ACA-Dock) feature, which enables upstream charging for portable devices with a USB On-The-Go (OTG) host.
EZ-USB™ HX2 is a family of high-performance, low-power USB 2.0 hub controllers. EZ-USB™ HX2LP is an ultra-low power single chip USB 2.0 hub controller with integrated upstream and downstream transceivers, a USB Serial Interface Engine (SIE), USB hub control and repeater logic, and TT logic.
Infineon EZ-USB™ family of hub controllers 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.
