USB2513BT/M2 - USB 2.0 3-Port Hub | Microchip
料号： USB2513BT/M2 ✓ 量产中USB2513BT/M2 概述
A USB hub controller is an interface IC within the broader semiconductor hierarchy of USB interface controllers, interface ICs, and connectivity semiconductors. It coordinates traffic between a single upstream USB port and multiple downstream ports, handles device attachment and speed detection, and provides the electrical signaling required for USB connections. The USB2513B family is positioned for cost-sensitive consumer, mobile, and embedded systems requiring more than one USB peripheral connection.
The verified product information identifies USB 2.0 Hi-Speed operation, three downstream ports, a 3.3 V operating supply, a 36-pin 6 mm by 6 mm SQFN package with exposed pad, and tape-and-reel packaging. Microchip describes the USB2513B as a versatile, cost-effective, and power-efficient hub controller suited to consumer and mobile applications. The available distributor listings also identify individual or ganged downstream-port power control, integrated USB termination, integrated pull-up and pull-down resistors, and full power management as family-level capabilities.
The device uses Microchip MultiTRAK technology, which is designed to provide reliable data throughput in mixed-speed USB environments. Mixed-speed support matters because USB 2.0 hubs can connect peripherals operating at 12 Mbit/s Low-Speed, 1.5 Mbit/s Full-Speed, or 480 Mbit/s High-Speed. Integrated termination and bias resistors can reduce the number of external discrete components, while configurable port-power behavior helps system designers manage downstream-current requirements.
Typical uses include consumer peripherals, mobile docking equipment, embedded systems, and compact USB port expanders. A system requiring three USB 2.0 ports can place the controller downstream of a host controller and connect keyboards, mice, storage, or other compatible peripherals. Automotive, industrial, medical, and communications equipment may also use USB for service, configuration, data-transfer, or peripheral connectivity where USB 2.0 compatibility is sufficient.
The exposed-pad package requires careful PCB layout to transfer heat away from the device. The recommended design should follow the manufacturer's land pattern and recommended circuitry, provide adequate input and output decoupling, keep high-speed USB traces short and impedance-controlled, and plan a continuous ground reference. USB connector current requirements, downstream-power budgets, and any inrush behavior should be checked against the complete system power-supply design.
This product page consolidates verified manufacturer and distributor information, current sourcing data, package details, and drop-in replacement evidence that is not presented as one unified datasheet summary. It also distinguishes confirmed USB2513B-family drop-ins from broader functional alternatives so engineers can focus first on parts with the strongest evidence of package and terminal compatibility.

典型应用
USB2513BT/M2 适用于 6 应用s: Consumer USB Port Expansion, Mobile Docking Systems, Embedded USB Service Interface, Industrial Data Acquisition, USB Storage and Media Hub, Medical and Diagnostic Accessories.
Consumer USB Port Expansion
The USB2513BT/M2 fits consumer peripherals that need to expose three USB 2.0 downstream ports from one host connection. It supports Low-Speed, Full-Speed, and High-Speed devices, allowing a single controller to serve keyboards, mice, storage, and other peripherals operating at different USB speeds. The verified 3.3 V supply and 36-pin SQFN package support compact board layouts, while integrated USB termination and pull-up and pull-down resistors can reduce external component count. Designers should budget power for all three downstream ports, implement the manufacturer land pattern, and route USB differential pairs as controlled-impedance traces with a continuous ground reference.
推荐
Mobile Docking Systems
USB2513BT/M2 is appropriate for mobile docking and accessory systems that consolidate several peripheral connections into one USB 2.0 upstream link. Its three downstream ports can support mixed-speed devices, while individual or ganged downstream-port power control allows the system to reduce unnecessary load when not every port is active. The 36-pin SQFN package is suitable for compact boards, but the exposed pad must be connected to the recommended thermal and ground structure. System validation should cover inrush current, downstream-device draw, connector detaches, and simultaneous Hi-Speed traffic across all three ports.
推荐
Embedded USB Service Interface
The USB2513BT/M2 can expand a single embedded host interface into three service or configuration ports for debug, data-logging, and field-upgrade accessories. Supporting Low-Speed through High-Speed devices makes it practical for a mix of legacy control peripherals and faster storage devices on the same hub. Because it operates at 3.3 V, the design must verify every attached accessory's signaling and power requirements rather than assuming USB bus voltage alone is sufficient. Maintain short USB traces, provide the prescribed capacitance at each port, and include protection appropriate to the connector environment.
推荐
Industrial Data Acquisition
USB2513BT/M2 is suitable for compact data-acquisition equipment requiring multiple USB connections to sensors, storage, and configuration equipment. Its mixed-speed support permits low-bandwidth control peripherals and high-bandwidth mass-storage devices to coexist on one controller. The three-port architecture can simplify enclosure connectors compared with separate hub chips, while integrated termination and bias components can reduce board complexity. Industrial implementations should still assess conducted noise, ground-loop behavior, ESD protection, and power-supply headroom. The USB2513BT/M2 should be paired with a host or MCU that implements the required host scheduling and enumeration behavior.
推荐
USB Storage and Media Hub
The USB2513BT/M2 can provide a three-port hub for storage, card-reader, and removable-media accessories in a compact media device. Hi-Speed support accommodates devices operating at the USB 2.0 limit of 480 Mbit/s, while Low-Speed and Full-Speed support allows simpler peripherals to share the same hub. Practical performance depends on the host controller, cable quality, flash-media responsiveness, and simultaneous traffic load, so the specification is a shared 480 Mbit/s bus rather than 480 Mbit/s per port. Validate enumeration, suspend and resume behavior, hot-plug handling, and downstream power limits during system testing.
推荐
Medical and Diagnostic Accessories
USB2513BT/M2 can support a medical or diagnostic accessory that needs to connect a host computer to multiple service peripherals, data loggers, or configuration tools. Its three downstream ports and mixed-speed operation allow a mix of control interfaces and higher-speed data devices to share a compact hub implementation. The controller does not itself establish medical compliance, so the finished equipment must assess its intended use, risk controls, electrical safety, and applicable regulatory requirements. Designers should provide dependable isolation where required, controlled USB routing, validated downstream-power management, and documented cleaning or sterilization constraints for connectors and enclosure materials.

设计说明
Follow the manufacturer's 36-pin SQFN land pattern and exposed-pad instructions without substituting a generic QFN layout. Place required input, output, and port-decoupling components close to their associated pins, and provide the specified via pattern beneath the exposed pad. Incorrect exposed-pad connections can impair thermal performance, grounding, or device operation. Confirm the final layout against the manufacturer package drawing and PCB stack-up before release.
Route each USB differential pair as a controlled-impedance pair over a continuous ground plane, minimize stub lengths, and avoid routing through plane splits or noisy power-regulator areas. The USB 2.0 Hi-Speed interface operates at 480 Mbit/s, so discontinuities and poor return paths can produce edge degradation. Use manufacturer-recommended topology around upstream and downstream ports, and verify the completed board with a scope and compliance testing appropriate to the finished product.
The three downstream ports share the hub's 3.3 V operating supply and USB port-current limits. Calculate worst-case demand with all enabled ports attached, including inrush, suspended-state behavior, cable loss, and attached-device peaks; the supplied results do not state the exact current limits, so obtain them from the manufacturer datasheet. Ensure the upstream supply, protection circuit, and power-distribution paths meet that calculated load without causing excessive droop or false disconnect events.
合规信息
