USB4604I-1080HN - USB 2.0 4-Port Hub Controller IC
料号： USB4604I-1080HN ✓ 量产中USB4604I-1080HN 概述
A USB hub controller is an interface integrated circuit that coordinates traffic between one upstream USB connection and multiple downstream USB ports. Within the device hierarchy, the USB4604I-1080HN is a USB interface controller, a USB 2.0 hub controller, and an embedded USB connectivity component. Its multi-transaction architecture allows USB traffic to be managed efficiently when several peripherals share limited host-controller resources.
The primary features include four downstream USB 2.0 ports, automatic protocol bridging between USB 1.1 and USB 2.0 devices, and a low-power operating mode. Additional integrated functions include power-on reset, wake-up support, and a built-in clock generator. These capabilities reduce the external circuitry and firmware coordination normally required for a compact embedded USB hub implementation.
The USB4604 family is designed around the USB 2.0 specification, the USB 2.0 Link Power Management Addendum, and the High-Speed Inter-Chip USB electrical specification. Its OEM-configurable architecture supports embedded equipment designs in which downstream-port behavior, power management, and wake-up requirements differ from a general-purpose desktop hub. The combination of 1.8 V and 3.3 V operation accommodates systems using low-voltage digital rails as well as conventional 3.3 V USB equipment.
Typical uses include industrial control panels, test and measurement systems, embedded computers, USB docking equipment, printers, storage peripherals, and multi-port charging or data-distribution equipment. The four-port configuration is particularly useful when a host must connect several low- to full-speed accessories while preserving USB 2.0 high-speed operation for compatible downstream devices.
The primary design concern is maintaining compliant USB signal and power routing on a dense 48-SQFN footprint. Follow the manufacturer’s pin-description and layout guidance for HSIC connections, supply decoupling, downstream-port routing, and exposed-pad thermal management. Confirm firmware configuration, enumerator behavior, and port-power requirements before releasing a production design.
This page organizes the USB4604 family’s verified architecture, package, interface, and feature information into practical guidance for embedded USB hub development. It also distinguishes confirmed drop-in options from functionally related controllers so engineers can avoid assuming that a similar USB hub controller has compatible pins, voltage requirements, or firmware behavior.

典型应用
USB4604I-1080HN 适用于 6 应用s: Embedded Industrial USB Hub, USB Test and Measurement Console, Industrial Data Acquisition Unit, USB-Audio and AV Accessory Hub, Printer and Storage Peripheral Hub, USB Docking and Connectivity Module.
Embedded Industrial USB Hub
The USB4604I-1080HN fits an embedded industrial hub because it combines four downstream USB ports with a low-power MTT architecture and OEM-configurable behavior. It can distribute one upstream host connection among peripherals operating at different USB protocol speeds while automatic protocol bridging manages interoperability. Operation from 1.8 V and 3.3 V supplies supports designs with mixed digital voltage domains. The 48-SQFN, 7 mm × 7 mm package also saves board area compared with a larger discrete hub implementation. Validate the operating-temperature range, enclosure thermal conditions, downstream-port power limits, and industrial qualification requirements before production release.
推荐
USB Test and Measurement Console
A test and measurement console can use the USB4604I-1080HN to connect several instruments, service tools, or data-acquisition peripherals to one host controller. Four downstream ports reduce the need for multiple external hubs, while the MTT transaction architecture supports efficient shared-bus operation. Automatic protocol bridging helps the console accommodate legacy USB 1.1 peripherals alongside USB 2.0 devices. Low-power mode and wake-up support are useful when the instrument must reduce activity between test sessions. Use the manufacturer’s recommended HSIC and downstream routing, and verify device-specific enumeration behavior and cable-length limitations during system qualification.
推荐
Industrial Data Acquisition Unit
The USB4604I-1080HN is appropriate for an industrial data-acquisition unit that must expose several USB-connected sensors, storage modules, or service interfaces to one embedded host. Four downstream ports provide a defined expansion path without requiring a larger host-only controller. Automatic protocol bridging allows mixed-speed USB peripherals to coexist, while OEM configuration permits port behavior to be tailored to the acquisition system. The controller’s low-power mode can reduce system activity when measurement cycles are idle, and wake-up can support controlled resumption. Confirm signal-routing tolerances, grounding strategy, port-power budgets, and firmware recovery behavior before deployment in electrically noisy environments.
推荐
USB-Audio and AV Accessory Hub
The USB4604I-1080HN can support an audio or AV accessory hub that connects several USB peripherals to an embedded media processor. Its four downstream ports permit concurrent attachment of control surfaces, storage devices, and compatible media accessories, while automatic protocol bridging handles devices operating at different USB speeds. The controller’s low-power design is advantageous in portable or intermittently powered equipment, and wake-up allows the system to activate from a suspended state. Use short, properly terminated USB routes and follow the manufacturer’s reference layout. Audio performance must be evaluated through the complete host, peripheral, cable, and firmware chain rather than inferred from the hub controller alone.
推荐
Printer and Storage Peripheral Hub
A printer, card reader, and mass-storage accessory can be consolidated behind a four-port USB hub built around the USB4604I-1080HN. The MTT architecture is suited to coordinating multiple transaction types across shared downstream ports, and automatic protocol bridging improves compatibility with both full-speed and high-speed USB devices. Low-power operation is useful in compact equipment where sustained idle activity matters. The controller does not provide external port-power switching or connector protection by itself, so the complete design must include suitable power distribution and protection. Validate each port’s current requirement, enumerate the intended peripheral set, and confirm restart behavior after cable reconnection or bus suspend.
推荐
USB Docking and Connectivity Module
The USB4604I-1080HN is well suited to a compact docking module that adds four downstream USB connections to an embedded platform. OEM configurability allows port characteristics to be aligned with the dock’s intended peripherals instead of using a fixed consumer-hub configuration. Operation at 1.8 V and 3.3 V supports integration with multiple internal voltage domains, while low-power mode and wake-up assist with portable or intermittently operated equipment. The 48-SQFN footprint preserves routing space in dense dock designs. Follow the manufacturer’s HSIC and exposed-pad recommendations, define downstream power budgets before layout, and test enumeration across all supported peripheral combinations and operating states.

设计说明
Route the upstream HSIC connection and all downstream USB paths according to the manufacturer’s reference layout. Keep HSIC traces short, use the recommended differential geometry, provide continuous return-path references, and avoid introducing stubs or unnecessary layer transitions. Place decoupling capacitors close to their designated supply pins and follow the exposed-pad connection instructions for the 48-SQFN package.
Define the downstream-port current budget before PCB implementation. The controller’s 1.8 V and 3.3 V operating options do not replace external port-power distribution or overcurrent protection. Use the manufacturer’s power architecture to determine which supplies power each downstream port, account for inrush during device connection, and keep switching or protection circuitry outside sensitive USB signal-return paths.
Do not treat the USB4604I-1080HN and USB4604I-1080HN-TR listings as different functional controllers; the TR suffix identifies the orderable packing form. Likewise, do not approve USB4624 or another USB hub controller as a drop-in replacement without checking the complete 48-SQFN terminal map, supply requirements, HSIC connectivity, and firmware behavior. Functional similarity alone does not establish pin compatibility.
Preserve the manufacturer’s package and exposed-pad land pattern, and account for thermal dissipation from the device and nearby port-power components. Place high-current switching components away from USB and HSIC routing, and maintain a low-impedance ground return between the controller, decoupling network, and connector structures. Review the assembled board for enclosure temperature rises and sustained downstream-port loading.
合规信息
The manufacturer product page identifies the USB4604 family as fully compliant with the USB 2.0 Specification, the USB 2.0 Link Power Management Addendum, and the High-Speed Inter-Chip USB electrical specification. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status require confirmation for the exact orderable part.
