The Microchip USB2512BT/M2: A Compact Powerhouse for Modern USB Hub and Charging Designs

In the realm of connectivity, the demand for efficient and intelligent hub solutions continues to grow. The Microchip USB2512BT/M2 stands out as a highly integrated, low-power USB 2.0 hub controller designed to meet this demand, offering a robust feature set tailored for both data distribution and dedicated charging applications.

This controller is a Hi-Speed 2-Port Hub that fully complies with the USB 2.0 specification, supporting data rates up to 480 Mbps. Its core architecture is built for reliability and seamless integration, making it an ideal choice for a wide array of products, from desktop peripherals and docking stations to embedded systems in automotive and industrial environments.

A key differentiator of the USB2512BT/M2 is its advanced Battery Charging Support. It incorporates dedicated hardware to comply with the USB Battery Charging Specification, Revision 1.2. This allows downstream ports to detect and provide enhanced charging current to connected devices—such as smartphones and tablets—even when the host system is suspended or powered off. This feature is critical for user convenience, enabling faster charging times without the need for a connected PC.

The hub's design emphasizes flexibility and ease of implementation. It is available in a compact, 36-pin lead-free SQFN package, which is ideal for space-constrained PCB designs. Furthermore, the device requires a minimal number of external components, which simplifies design-in and helps reduce the overall Bill of Materials (BOM) cost. Its low operating power consumption is a significant advantage for power-sensitive and portable applications.

Internally, the hub features fully integrated USB termination resistors and a built-in 5V-to-3.3V voltage regulator, further contributing to its component count reduction. It also supports custom configuration via a single serial I²C EEPROM interface or through a set of configurable strap pins, allowing designers to tailor its functionality—such as port mapping and LED behavior—to their specific needs without complex software drivers.

ICGOODFIND: The Microchip USB2512BT/M2 is a superior solution for designers seeking a reliable, cost-effective, and feature-rich USB hub IC. Its integrated battery charging support, low power footprint, and minimal external component requirement make it an excellent choice for streamlining the development of modern, user-friendly connected devices.
