USB2514-HZH 概述
A USB hub controller is an interface integrated circuit that manages traffic between an upstream host or root hub and multiple downstream USB devices. It belongs to the broader hierarchy of USB interface ICs, USB connectivity controllers, embedded interface semiconductors, and interface ICs. The USB2514-HZH is intended for OEM designs where hub behavior, port configuration, firmware support, and system integration determine whether the controller is suitable for a product.
The verified data specifically describes the USB2514-HZH as a USB 2.0 high-speed four-port hub controller with four downstream ports. It is also described as low power and OEM configurable. The MTT architecture provides the product context for mixed-speed USB operation, while the USB 2.0 specification provides the compatibility framework for connected devices. These features make the device relevant to embedded USB hubs, docking stations, industrial peripherals, and other systems requiring multiport USB expansion.
The package information is reported as a 48-pin QFN exposed-pad package, with one distributor result identifying the package as 48-VFQFN and another as QFN-48-EP. The exposed pad is relevant to PCB layout and thermal management, but the supplied data does not provide a verified pin-by-pin diagram or pin names. Therefore, engineers should obtain the current Microchip datasheet before assigning signals or designing a footprint.
Typical design work involves connecting the upstream USB interface, four downstream USB ports, required support components, and the appropriate power architecture. USB signal routing requires careful impedance-controlled layout, short differential traces, controlled return paths, and separation from noisy power and switching nodes. Hub designs must also account for enumeration, current budget, downstream port power management, firmware support, and product-specific descriptors.
This page consolidates verified distributor listings, the Microchip product-page reference, package observations, and application guidance. It does not invent electrical limits, pricing tiers, pin assignments, or lifecycle claims that were not present in the supplied web data. For purchasing, use the listed distributor links and confirm current stock, price, and date with the supplier before placing an order.

典型应用
USB2514-HZH 适用于 6 应用s: Embedded USB Hub, Industrial USB Expansion, Docking Station, Test and Measurement Instrument, Set-Top Box, USB Peripherals.
Embedded USB Hub
The USB2514-HZH fits an embedded USB hub because the verified product description identifies a USB 2.0 high-speed four-port hub controller with four downstream ports. Place it between one upstream host connection and four external USB ports, then validate enumeration, power management, and host-driver behavior in the finished system. The controller is suitable when the design needs more USB expansion than a single host port provides and can accommodate a 48-pin QFN exposed-pad implementation.
推荐
Industrial USB Expansion
For industrial equipment, the four downstream ports of USB2514-HZH can connect keyboards, storage devices, service interfaces, or other USB peripherals to one embedded controller. Its USB 2.0 high-speed hub function and low-power positioning make it relevant to industrial panels and embedded systems, while the exact operating temperature and supply limits must be verified from the current datasheet. Robust grounding, surge protection, and controlled USB power distribution are especially important outside a desktop enclosure.
推荐
Docking Station
USB2514-HZH can provide the USB hub core in a docking station that needs four downstream ports behind a single upstream connection. The verified USB 2.0 high-speed classification supports the intended hub use case, while MTT technology provides the stated context for mixed-speed USB environments. A dock design must still budget downstream power, define port overcurrent behavior, maintain high-speed signal integrity, and verify that the host enumerates every attached device reliably.
推荐
Test and Measurement Instrument
A USB2514-HZH-based hub can give a test or measurement instrument multiple USB service connections without requiring several host ports. The four downstream ports allow a laptop or embedded controller to access storage, configuration adapters, and peripheral interfaces. Because the supplied data does not specify operating temperature, supply voltage, or port electrical limits, the instrument should be designed after reviewing the current Microchip datasheet and validating suspend, resume, enumeration, and cable-length behavior.
推荐
Set-Top Box
USB2514-HZH may be considered for a set-top box or media appliance that needs to connect several USB peripherals through one embedded host interface. Its four-port USB 2.0 hub architecture is useful for storage, keyboards, remotes, and service connections, while the low-power design intent supports compact embedded systems. The design must account for the appliance's supply budget, USB port protection, chassis grounding, and the specific host software and descriptors expected by the product.
推荐
USB Peripherals
The USB2514-HZH can serve as the four-port expansion element inside a larger USB peripheral or adapter assembly. Its upstream link keeps the embedded system connected to one host port while downstream ports serve multiple external devices. For this use, pay particular attention to the package's exposed pad, USB differential impedance, connector placement, overcurrent protection, and host compatibility. Firmware configuration and product descriptors should be tested across the full range of attached USB device speeds.

设计说明
Route the upstream and downstream USB differential pairs as controlled-impedance traces with short, matched paths and continuous reference planes. Keep USB traces away from switching regulators, high-current inductor nodes, clocks, and other noisy nets. The supplied data does not specify a target differential impedance, so use the USB implementation guidance and connector requirements of the final system rather than assuming a value.
Use the manufacturer's land pattern for the 48-pin QFN exposed-pad package and preserve the exposed-pad thermal connection. Place decoupling and required support components close to the associated power and signal pins, while keeping USB connector paths short. Verify the exact package drawing, exposed-pad dimensions, pin numbering, and solder-mask clearance before fabrication because those details are not included in the supplied verified data.
Design the downstream USB power budget before committing the hub power architecture. Four downstream ports can create substantially more load than one upstream port, so each port's required current, cumulative supply limit, inrush behavior, and protection strategy must be checked against the system supply. The supplied sources do not provide the controller's electrical current limits, so use the current Microchip datasheet and validate the complete power tree in hardware.
Do not treat a related USB2514-family MPN as a drop-in replacement solely because it appears in a comparison search. Confirm package pinout, exposed-pad connections, USB timing, port count, firmware, descriptors, power behavior, and host-driver compatibility. The supplied cross-reference results identify related parts but do not provide enough verified data to establish direct substitution for USB2514-HZH.
The exposed pad is a thermal and electrical feature that must be implemented according to the manufacturer footprint and assembly process. For an embedded hub, estimate heat from the USB power-conversion path and the controller's operating current, then provide copper area and thermal vias appropriate to the enclosure. Because the supplied data does not include junction temperature, thermal resistance, or maximum power values, those figures must be obtained from the current datasheet before sizing cooling.
合规信息
The supplied verified web data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-mineral status for USB2514-HZH. Related comparison pages mention RoHS and REACH for other parts, but that evidence was not transferred to the target component.
