USB2513BT-I/M2 - 3-Port USB 2.0 Hub Controller | Microchip
N.º da peça: USB2513BT-I/M2 ✓ AtivoUSB2513BT-I/M2 Visão geral
A USB hub controller is a semiconductor that manages one upstream USB connection and multiple downstream ports. USB 2.0 hub controllers combine USB bus-interface logic, port power management, current protection, and device enumeration functions. They sit between a host controller and external peripherals, making them part of the wider USB interface and power-management ecosystem.
The controller provides three downstream USB ports, USB 2.0 Hi-Speed operation, and a 3.3 V operating supply. According to the Microchip product information, the USB2513B family supports mixed-speed USB environments while maintaining efficient power use. Battery-charging support, port power-switch control, an internal regulator, ESD protection, and overcurrent protection are also listed for the device.
The USB2513BT-I/M2 uses Microchip MultiTRAK technology to manage traffic across low-, full-, and high-speed devices connected to the same hub. This mixed-speed support is important for systems that must remain compatible with legacy peripherals while also supporting USB 2.0 high-speed devices. Its 36-SQFN package supports compact PCB placement in consumer, mobile, and embedded USB equipment.
Typical applications include USB expansion in laptops, tablets, docking products, set-top equipment, printers, and compact embedded systems. It is particularly suitable when a platform needs more USB connectivity than its system controller provides and when downstream ports require coordinated power switching and current protection.
PCB implementation should preserve the USB high-speed layout required by the manufacturer, including a continuous reference plane, controlled impedance routing, short differential pairs, and placement of support components near the appropriate pins. Port protection and power-switch selection must also be checked against the downstream current requirements of the final device.
This page combines manufacturer feature information, drop-in replacement guidance, application-specific engineering guidance, and a parameter comparison to support faster component selection and PCB design planning.

Aplicações típicas
USB2513BT-I/M2 é adequado para 6 aplicaçãos: Mobile Device USB Expansion, Laptop and Docking Systems, Consumer Perimeter Devices, Industrial USB Data Acquisition, USB-to-Ethernet Connectivity, Embedded USB Service Port.
Mobile Device USB Expansion
The USB2513BT-I/M2 fits mobile platforms that expose three USB 2.0 downstream ports from a common 3.3 V supply. Its three-port hub architecture reduces the number of separate downstream interfaces required from the host controller, while support for low-, full-, and high-speed devices preserves compatibility with legacy accessories. The 36-SQFN 6 mm by 6 mm package also supports compact board layouts. In a tablet or portable accessory, the controller can manage downstream port power switching, current protection, and enumeration while the manufacturer reference design establishes the required support network and layout. Battery-powered designs should verify suspend behavior, downstream current demand, and thermal performance across the complete accessory load.
Recomendado
Laptop and Docking Systems
The USB2513BT-I/M2 is appropriate for a laptop dock or peripheral expansion board that must provide three downstream USB 2.0 connections. Its mixed-speed operation allows low-speed and full-speed legacy peripherals to coexist with high-speed storage or networking accessories on the same hub. The controller provides BC1.1 support, port power-switch control, ESD protection, and overcurrent protection, which help organize downstream power and fault handling. In a compact dock, the 36-SQFN package preserves routing space, but designers must preserve the USB high-speed signal topology, provide adequate downstream power, and confirm that each port remains within the controller and power-switch system limits.
Recomendado
Consumer Perimeter Devices
The USB2513BT-I/M2 can add three USB 2.0 ports to a compact consumer peripheral, printer, set-top product, or media device. Its fixed-function hub implementation avoids the software and firmware overhead of a programmable USB controller when only standard host-to-hub enumeration is required. Support for low-, full-, and high-speed devices makes it useful where consumers may attach keyboards, mice, storage, or service adapters with different USB capabilities. The 36-SQFN device should be placed to support short USB traces, while external power switches must be sized for the attached load. Firmware should also handle port connect, disconnect, suspend, and overcurrent events expected from real consumer peripherals.
Recomendado
Industrial USB Data Acquisition
The USB2513BT-I/M2 is suitable for industrial data-acquisition equipment that needs multiple USB 2.0 service connections while retaining compatibility with slower legacy instruments. Three downstream ports can support control, storage, and diagnostic accessories, while the internal regulator, ESD protection, and overcurrent protection support practical peripheral integration. The controller operates from 3.3 V and accepts low-, full-, and high-speed devices, allowing the enclosure to support a broad accessory mix. In an acquisition system, designers should reserve the exposed-pad copper area, follow the manufacturer high-speed layout rules, and isolate noisy power paths. Environmental requirements for temperature, immunity, and long-life supply should be confirmed separately before production release.
Recomendado
USB-to-Ethernet Connectivity
The USB2513BT-I/M2 can serve as the USB-facing hub controller in compact network and docking products that combine USB peripherals with Ethernet connectivity. Three USB 2.0 downstream ports provide room for an Ethernet adapter, storage device, and service interface, while the mixed-speed operation accommodates both legacy and high-speed peripherals. Its 3.3 V operating supply and compact 36-SQFN package align with compact embedded network hardware. The implementation should provide a continuous reference plane and controlled-impedance USB routing, while Ethernet magnetics and isolation requirements remain independent of the hub controller. Validate simultaneous enumeration, suspend/resume behavior, and the aggregate power budget when multiple high-bandwidth peripherals operate together.
Recomendado
Embedded USB Service Port
The USB2513BT-I/M2 is useful in embedded equipment that needs more than one service or maintenance connection without implementing a programmable USB controller. A three-port arrangement can support a configuration interface, data-logging device, and recovery adapter, and the controller handles downstream power switching and fault protection functions listed by Microchip. Low-speed and full-speed support remains valuable for legacy service tools even when high-speed devices are used elsewhere. In an embedded controller board, place the hub close to the external connectors and follow the manufacturer’s USB routing and reference-circuit guidance. Firmware must enumerate unexpected devices safely, monitor current faults, and provide controlled recovery when a downstream peripheral is disconnected during operation.

Notas de projeto
Place the USB2513BT-I/M2 and its required support components close to the upstream and downstream USB connectors. Maintain a continuous ground reference beneath high-speed routes, use controlled-impedance differential pairs, minimize stubs, and avoid placing disruptive power or switching nodes near the USB signals. Follow the pin-description and reference-layout tables in the manufacturer datasheet before assigning tracks or test points.
Size the upstream 3.3 V supply and downstream power switches for the selected USB port-current configuration, including startup, charging, and fault-current conditions. The listed internal regulator and overcurrent protection features do not remove the need to validate the external power-distribution network. Check voltage tolerance, inrush behavior, and total downstream demand against the manufacturer electrical limits before release.
The 36-SQFN package includes a thermal connection that must be tied to the board ground plane using the manufacturer land pattern. Copper area and via distribution should be evaluated against power-switch dissipation and the enclosure temperature. For estimated thermal analysis, calculate each switch's conduction loss from its actual voltage drop and current, then compare the resulting junction temperature with the device limit.
Do not treat a similar USB2513-family ordering code as interchangeable without checking temperature grade, package orientation, tape-and-reel orientation, exposed-pad requirements, and all pin assignments. Also avoid assuming that a four-port USB2514-family device is a drop-in replacement: its extra port changes the functional configuration even when the package dimensions are similar.
