The Microchip USB2513B-I/M2: A Compact Powerhouse for USB Hub Integration

In the realm of modern electronics, the need for expanding USB connectivity is ubiquitous. The Microchip USB2513B-I/M2 stands out as a highly integrated, 3-port USB 2.0 Hi-Speed hub controller designed to provide a robust and flexible solution for a wide array of applications. This compact integrated circuit (IC) serves as a critical bridge, enabling a single USB host connection to be expanded into three downstream ports, each capable of supporting the high-speed data rate of 480 Mbps.

A key strength of the USB2513B-I/M2 lies in its advanced feature set and design simplicity. The device is fully compliant with the USB 2.0 specification and requires a minimal number of external components, which significantly reduces both the board space required (thanks to its small 4x4 mm 24-pin QFN package) and the total bill of materials cost. It incorporates integrated USB termination and pull-up/pull-down resistors, further simplifying the PCB layout process for designers. Its support for individual or ganged power switching and overcurrent protection for each downstream port offers unparalleled design flexibility, allowing it to be optimized for both self-powered and bus-powered configurations.

The hub controller also boasts sophisticated capabilities that enhance system performance and power management. Features like dynamic power control, which allows ports to be powered down when not in use, and multi-transaction translator (Multi-TT) architecture, which maximizes bandwidth and minimizes latency for full-speed and low-speed devices connected simultaneously, are integral to its design. Furthermore, it supports vendor-specific commands for custom configuration, making it adaptable for specialized use cases.

Typical applications for the USB2513B-I/M2 are extensive, ranging from desktop and notebook docking stations to industrial control systems, embedded computing modules, and a vast array of consumer peripherals. Its reliability and small form factor make it an ideal choice for space-constrained designs where performance cannot be compromised.

ICGOOODFIND: The Microchip USB2513B-I/M2 is a highly efficient and cost-effective solution for adding multi-port USB 2.0 Hi-Speed hub functionality. Its combination of a small footprint, low external component count, and rich feature set makes it an exceptional choice for designers seeking to implement reliable and high-performance USB expansion.
