概述
Description
FSUSB73UMX is a USB hub/controller IC from the FSUSB family (Fairchild Semiconductor, now ON Semiconductor). It provides hub functionality: one upstream port to connect to a host and multiple downstream ports to attach USB devices. It implements USB 2.0 High-Speed transceivers and handles hub management, device enumeration, and port-power control. The device includes features useful in embedded designs such as port overcurrent protection, ESD protection, and low-power modes. The “UMX” suffix indicates the package type (a compact surface-mount package). Typical applications are adding USB ports to a system (PC peripherals, embedded devices, docking stations). For exact port count, electrical specs, and power requirements, refer to the latest datasheet.
