USB2513-AEZG - 3-Port USB 2.0 Hub Controller | Microchip
Артикул: USB2513-AEZG ✓ АктивенUSB2513-AEZG Обзор
A USB hub controller is an interface integrated circuit that expands one upstream USB connection into multiple downstream ports. In the product hierarchy, it belongs to interface ICs, USB interface controllers, and the broader semiconductor category. Its principal function is transaction translation, device enumeration, and coordinated data transfer between an upstream USB host and attached peripherals.
The USB2513-AEZG uses Microchip Multi-Transaction Translator technology for USB 2.0 operation in mixed-speed environments. The verified product information identifies three downstream ports, USB 2.0 high-speed support, low-power operation, OEM configurability, and an industrial-temperature-rated version. Its 36-QFN-EP package supports compact embedded layouts while providing an exposed pad for board-level thermal management.
This controller is intended for embedded USB designs where a host processor or equipment controller needs to connect multiple external devices. The controller must manage upstream and downstream USB connections while respecting the power, signal-integrity, and enumeration requirements of the USB 2.0 specification. Detailed electrical limits and timing values are not included in the supplied verified excerpts and should be confirmed in the manufacturer datasheet before schematic release.
Typical uses include industrial control panels, embedded computing systems, test equipment, printers, and industrial peripherals. A USB2513-AEZG can reduce the need for separate downstream routing in a compact product by presenting three logical downstream ports from one upstream interface. Designers must still budget upstream and downstream connection budget, supply current, cable routing, and connector protection according to their system architecture.
The most important design consideration is to validate the complete USB topology with the manufacturer reference design and electrical guidance. Place the exposed-pad thermal path through the PCB stack-up, route high-speed differential pairs as controlled-impedance nets, and place required bypass capacitance close to the supply pins. Do not infer unsupported electrical limits from the distributor summaries alone.
This product page consolidates verified distributor descriptions, package information, sourcing links, comparison data, and drop-in replacement guidance. It distinguishes directly documented facts from specifications that still require confirmation from the complete USB2513-AEZG manufacturer datasheet, helping engineers make an initial component-selection and sourcing assessment.

Типичное применение
USB2513-AEZG подходит для 6 применениеs: Industrial Control Panels, Embedded Computing Systems, Test and Measurement Equipment, Printers and Peripherals, Industrial Networking Gateways, Portable and Field-Service Equipment.
Industrial Control Panels
The USB2513-AEZG suits industrial control panels that need to connect several service peripherals to one embedded controller. Its three downstream USB 2.0 ports consolidate peripheral connections without requiring three independent host controllers, while the industrial-temperature-rated configuration supports demanding equipment environments. The 36-QFN-EP 6 x 6 mm package also reduces board area compared with a discrete multi-port implementation. Engineers should verify the complete electrical limits and USB power budget in the manufacturer datasheet, then use controlled-impedance routing for upstream and downstream differential pairs.

Embedded Computing Systems
The USB2513-AEZG provides a practical way to expand USB connectivity in embedded Linux, industrial computer, and appliance designs. One upstream USB interface is translated into three downstream ports, allowing keyboard, storage, communications, and service interfaces to share the host controller. The MTT architecture supports USB 2.0 operation in mixed-speed environments, while low-power operation is valuable in compact equipment. The implementation must account for enumeration, hub descriptors, connection budget, and the physical USB routing required around the compact exposed-pad package.
Рекомендуется
Test and Measurement Equipment
The USB2513-AEZG can organize USB service connections in test and measurement instruments that expose several peripherals to a single host computer. The three downstream ports can support devices such as a control interface, memory device, or service adapter, reducing the number of direct host ports required. USB 2.0 high-speed operation and MTT transaction translation provide a suitable foundation for mixed-speed peripheral environments. Designers should consider port overcurrent protection, cable-length limitations, grounding, and enclosure EMI requirements while preserving the required USB differential impedance.
Рекомендуется
Printers and Peripherals
The USB2513-AEZG is applicable to printers, scanners, and compact peripheral products that need to expose more than one USB connection through an embedded controller. Its three downstream ports can simplify internal cable routing and provide a common USB 2.0 interface for service, storage, and configuration functions. The low-power, OEM-configurable controller architecture supports integration into a designed product rather than a general-purpose external enclosure. A production design must validate available bus current, connector standards, host compatibility, and the behavior of low-, full-, and high-speed devices on each downstream port.
Рекомендуется
Industrial Networking Gateways
The USB2513-AEZG can support USB expansion in gateways that connect diagnostic equipment, local storage, or configuration interfaces to an embedded communications processor. Three downstream USB 2.0 ports provide useful flexibility without requiring a processor with three integrated host controllers. Its industrial-temperature-rated construction is appropriate for gateways deployed in controlled industrial spaces, subject to confirmation of the exact temperature limits. Layout should keep the exposed pad thermally connected, isolate noisy interfaces, and route USB differential signals away from switching power-conversion nodes.
Рекомендуется
Portable and Field-Service Equipment
The USB2513-AEZG can expand service connectivity in portable diagnostic and field-service equipment where multiple USB accessories must connect to one embedded processor. The controller's three-port topology and low-power operation are useful when the enclosure provides limited space, while OEM configuration allows hub behavior to be integrated with the product's firmware and descriptor strategy. The 36-QFN-EP package needs careful exposed-pad soldering and thermal verification. Engineers should also budget connector protection, ensure cable strain relief, and validate suspend, resume, and power-consumption behavior across the complete system.

Заметки по проектированию
Route upstream and downstream USB differential pairs as controlled-impedance traces on the same PCB layer where practical, following the manufacturer's reference stack-up and the applicable USB impedance target. Avoid stubs, test pads, and unnecessary vias on high-speed pairs. Keep the upstream connection and downstream port geometry consistent with the manufacturer reference design because signal integrity at a hub depends on both trace geometry and the attached cable and connector path.
The USB2513-AEZG uses a 36-QFN exposed-pad package, so the exposed thermal pad must be connected to a solid copper region using the manufacturer-recommended via pattern. Thermal performance depends on the complete board stack-up and enclosure, not just the package dimensions. Verify junction-temperature limits under the maximum expected USB traffic and ambient condition using the datasheet's thermal model; no numeric thermal resistance was present in the supplied verified excerpts.
Design the 3.3 V supply path for both controller demand and the applicable USB port-current budget. Place required bypass capacitors at the controller's supply pins, keep the return path continuous, and account for inrush and hot-plug behavior at downstream connectors. If downstream devices draw substantial current, use the system power architecture and protection devices described by the manufacturer rather than assuming the hub's 3.3 V rail can source external-device power.
Do not treat a matching package name as proof of a drop-in replacement. The USB2513BI-AEZG is explicitly documented as pin-compatible, but device identifiers, hub descriptors, firmware support, configuration masks, and production programming may still affect behavior. For USB2513B-AEZG, verify the exact suffix, package drawing, exposed-pad layout, and configuration. Before substitution, test enumeration, suspend and resume, over-current recovery, and simultaneous high-speed traffic.
