USB2513BI-AEZG-TR 3-Port USB 2.0 Hub | Microchip Technology (Tape & Reel)
N.º de pieza: USB2513BI-AEZG-TR ✓ ActivoUSB2513BI-AEZG-TR Descripción general
A USB hub controller is a semiconductor that manages traffic between a USB host and one or more downstream USB ports. The USB2513BI family combines configurable USB 2.0 routing, low-power operation, and MultiTRAK transaction handling in one controller. Its position within the hierarchy is USB interface controller → USB hub controller → embedded USB interface IC, allowing one upstream connection to expand into multiple downstream ports.
Three principal characteristics define the USB2513BI-AEZG-TR: three USB 2.0 high-speed ports, a 3 V to 3.6 V supply range, and a 36-QFN 6 mm × 6 mm package. The family description also identifies configurable operation, low power consumption, and MultiTRAK technology for mixed-speed USB environments. These characteristics make the controller appropriate where a host interface must support several peripherals without using a full-size host computer.
The MultiTRAK architecture is significant because it supports predictable handling of multiple USB transactions through the hub. Compared with basic four-wire hub implementations, a dedicated USB 2.0 controller can integrate device enumeration, configuration, status monitoring, and downstream-port management. The I²C EEPROM interface permits external configuration storage, while the SMBus interface provides a two-wire management path suitable for embedded platform control and diagnostics.
Typical uses include compact consumer hubs, mobile accessories, embedded USB expansion, docking systems, and mixed-speed peripheral arrangements. In a docking application, the upstream USB connection can feed multiple external peripherals while the controller manages enumeration and port transactions. In a mobile accessory, the low-power 3.3 V-class operating range and compact QFN footprint help limit board area, although final thermal and power performance depend on the complete system implementation.
Designers should preserve the manufacturer's recommended external-component and layout arrangement around the controller. The I²C EEPROM interface, USB data routing, power-supply connections, and decoupling network must be implemented according to the device pin description and reference circuitry. The package has 36 terminals, so use the 36-pin QFN pinout rather than a generic 32-pin or 40-pin footprint when assigning PCB pads and checking continuity.
This page combines the manufacturer's product description, USB family characteristics, package information, interface details, and application-oriented engineering guidance. It also separates confirmed direct alternatives from broader family comparisons, helping engineers identify the correct USB hub controller and verify footprint, port count, supply range, and configuration requirements before committing a PCB layout.

Aplicaciones típicas
USB2513BI-AEZG-TR es adecuado para 6 aplicacións: Compact Consumer USB Hub, Mobile Accessory Port Expansion, Embedded USB Docking Station, Mixed-Speed Peripheral Hub, Industrial USB Interface Expansion, USB-to-Device Interface Bridge.
Compact Consumer USB Hub
The USB2513BI-AEZG-TR fits a compact consumer hub that expands one host connection into three USB 2.0 high-speed ports. Its 36-QFN 6 mm × 6 mm package helps preserve board area, while MultiTRAK transaction handling supports multiple downstream devices in a mixed-speed environment. The 3 V to 3.6 V supply range suits a regulated 3.3 V implementation. Designers should use the manufacturer reference circuit for USB routing and decoupling, while handling downstream-port power, current protection, and connector mechanics separately.
Recomendado
Mobile Accessory Port Expansion
The USB2513BI-AEZG-TR is appropriate for a mobile accessory that needs three USB 2.0 high-speed connections without adding a host computer. Its low-power controller family and compact 36-QFN package support portable product constraints, and the I²C EEPROM interface allows external configuration storage. The SMBus connection can support platform-level monitoring or control. Final suitability depends on the accessory's power budget, connector arrangement, USB enumeration behavior, and whether the operating environment remains inside the device's specified electrical limits.
Recomendado
Embedded USB Docking Station
A docking system can use the USB2513BI-AEZG-TR to manage three USB 2.0 high-speed downstream ports from one upstream host connection. The controller centralizes port configuration and transaction handling, reducing the host's direct USB interface burden. The I²C EEPROM connection supports configuration storage, while SMBus gives the dock controller a two-wire management channel. Product-specific safeguards must include supply-current budgeting, port disconnect behavior, ESD protection, and the manufacturer's recommended USB trace and return-path geometry.
Recomendado
Mixed-Speed Peripheral Hub
The MultiTRAK architecture makes the USB2513BI-AEZG-TR relevant to mixed-speed peripheral arrangements in which USB 2.0 high-speed and lower-speed devices share a hub. Three downstream ports provide room for storage, control, and human-interface devices while preserving a single upstream interface. The controller's configurable design supports platform-specific port behavior, but the system designer must validate enumeration timing, device-specific power requirements, and class-driver compatibility. Configuration memory and host software should follow the manufacturer's register guidance.
Recomendado
Industrial USB Interface Expansion
The USB2513BI-AEZG-TR can provide USB port expansion in an industrial controller or service module that needs to connect three USB peripherals to an embedded platform. Its 3 V to 3.6 V operating range and compact surface-mount package simplify integration into a regulated embedded board. The SMBus interface offers a separate management path for diagnostics or supervisory control. Before deployment, confirm the device's operating-temperature limits, verify downstream power-cycle behavior, and implement connector protection appropriate to the installation environment.
Recomendado
USB-to-Device Interface Bridge
The USB2513BI-AEZG-TR can serve as the hub element in an embedded interface bridge that presents three controlled USB ports to an external host. This arrangement is useful when a compact peripheral needs to aggregate several USB connections without implementing a full USB host. The controller handles downstream hub transactions, while the primary system processor manages class-specific functions. Interface implementation must account for EEPROM initialization, identification registers, port power timing, and any USB-IF compliance requirements that apply to the finished product.

Notas de diseño
Use the exact 36-terminal QFN land pattern from the manufacturer package drawing. The exposed center pad and 36 peripheral terminals do not match a generic 32-pin or 40-pin QFN footprint. Place the controller close to its USB connector and supply components, minimize stub lengths on high-speed USB differential pairs, and provide a continuous return-path reference beneath the routed pair.
The controller operates from 3 V to 3.6 V, so connect it to a regulated rail within that range. Keep input and output decoupling close to the device pins and follow the manufacturer reference circuit for component values and placement. Downstream USB port power is a separate design consideration: calculate each connector's worst-case current demand and size the port-power switches, protection, and supply network independently from the controller's core supply.
Do not assume that every USB251xB family device is an automatic functional substitute. The family datasheet states that product IDs, device IDs, and register defaults may differ even when the PCB is pin-compatible. Confirm downstream-port count, EEPROM initialization, device identity, host enumeration behavior, and any software-visible register changes before replacing the USB2513BI-AEZG-TR in production hardware.
Follow the manufacturer's USB routing and reference-circuit recommendations rather than routing solely for nominal trace length. Provide clean supply and ground connections, keep the I²C EEPROM and SMBus traces away from noisy switching nodes, and observe the required connection geometry for the QFN exposed pad. Verify differential-pair impedance, via symmetry, and return-path continuity with the PCB fabricator's stack-up.
