The USB2514BT/M2: Powering Next-Generation USB 2.0 Hub Applications

In the realm of connectivity, the demand for efficient and versatile USB hub solutions remains strong, particularly for embedded systems and desktop peripherals. The USB2514BT/M2 stands out as a highly integrated, 4-port USB 2.0 hub controller designed to meet this demand, offering a robust feature set that emphasizes both data connectivity and advanced battery charging support.

This controller simplifies design and reduces external component count by integrating all the necessary logic and termination resistors. Its core function is to provide a seamless expansion of a single upstream USB port into four downstream ports. Each of these downstream ports can be independently configured and controlled, offering designers significant flexibility. A key differentiator for the USB2514BT/M2 is its sophisticated battery charging emulation support. It incorporates dedicated circuitry that complies with multiple popular charging protocols, including the USB Battery Charging Specification Rev. 1.2 (BC1.2) and a variety of legacy proprietary schemes for Apple and Samsung devices. This allows connected devices to identify the hub as a dedicated charging port (DCP), enabling them to draw the maximum allowable current for faster charging, even when the host system is suspended or powered off.

The hub supports both bus-powered and self-powered configurations, providing further design versatility. Its low operating power consumption makes it an excellent choice for power-sensitive applications. Furthermore, the USB2514BT/M2 comes in a compact, space-saving 36-pin QFN package, ideal for modern, miniaturized PCB designs.

ICGOOODFIND: The USB2514BT/M2 is an optimal solution for designers seeking a reliable, feature-rich USB 2.0 hub IC. Its integrated battery charging emulation, low power footprint, and high level of integration make it a superior choice for a wide array of products, from docking stations and monitors to industrial embedded systems, ensuring fast charging and stable data transfer.
