Microchip USB5744/2GX01: A 4-Port USB 2.0 Gen 1 Smart Hub Controller for Modern Connectivity

In an era where the number of peripheral devices continues to grow, the demand for robust and intelligent USB hub solutions has never been greater. The Microchip USB5744/2GX01 stands out as a highly integrated, industrial-grade controller designed to meet this need, offering a sophisticated blend of performance, flexibility, and power management.

This controller is a 4-Port USB 2.0 Gen 1 Hub, supporting data transfer speeds of up to 480 Mbps per port. It is engineered to provide seamless connectivity for a wide array of devices, from keyboards and mice to external storage and audio interfaces. A key feature of the USB5744 is its high level of integration. The controller incorporates a USB 2.0 hub, a serial interface engine (SIE), and a hub repeater onto a single chip, significantly reducing the bill of materials (BOM) and simplifying PCB design for manufacturers.

Beyond basic connectivity, the "Smart Hub" designation is well-earned. The device includes advanced power management capabilities, allowing each downstream port to be individually powered and controlled. This enables features like per-port power switching and over-current detection, which are crucial for protecting both the hub and the connected devices from electrical faults. Furthermore, it supports multiple downstream port configurations (4, 3, 2, or 1 port) through strapping options or I²C/SMBus interface, providing designers with exceptional design flexibility.

The USB5744/2GX01 also supports battery charging applications, implementing dedicated charging port (DCP) functionality as per the USB Battery Charging Specification Rev. 1.2. This allows compatible devices like smartphones and tablets to charge more quickly even when not actively transferring data. Its industrial temperature range (-40°C to +85°C) makes it suitable not only for consumer products but also for demanding automotive, industrial, and medical applications where reliability is paramount.

ICGOODFIND: The Microchip USB5744/2GX01 is a premier solution for developers seeking to create reliable, feature-rich USB hub systems. Its combination of high integration, robust power management, and configuration flexibility makes it an ideal choice for streamlining design processes and enhancing end-product functionality across a diverse range of markets.
