The Microchip USB4604I-1080HN-TR: A Robust 4-Port Hi-Speed USB Hub Controller
In the realm of modern connectivity, the USB hub remains a fundamental component for expanding the limited port offerings of computers and embedded systems. The Microchip USB4604I-1080HN-TR stands out as a highly integrated, industrial-grade solution designed to deliver reliable and high-performance connectivity. This 4-port hub controller is engineered to meet the demanding requirements of both consumer and industrial applications, providing a seamless interface for a multitude of USB 2.0 peripherals.
At its core, this controller is a single-chip solution that simplifies design and reduces both board space and bill-of-materials (BOM) costs. It fully complies with the USB 2.0 specification, supporting Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data transfers. Each of its four downstream ports can operate simultaneously, ensuring that connected devices—from keyboards and mice to external storage drives—perform without bottlenecks.
A key feature of the USB4604I-1080HN-TR is its advanced power management. The hub supports individual port power switching and over-current detection for each downstream port, granting designers precise control over power distribution and enhancing the protection of connected devices. This is crucial for robust system design, preventing fault conditions from cascading and causing widespread failures. Furthermore, the device can be configured via external Serial PROM or through its SMBus interface, offering flexibility for specific application needs.
The "HN" in its part number denotes a 9x9mm 68-pin QFN package, which is ideal for space-constrained applications while also offering excellent thermal performance. The industrial temperature range rating ensures stable operation in harsh environments, making it suitable for applications in industrial automation, medical equipment, and point-of-sale systems where reliability is paramount.
ICGOO FIND: The Microchip USB4604I-1080HN-TR is an exemplary hub controller that combines high integration, robust power management, and industrial durability. It is an optimal choice for designers seeking a dependable, high-performance USB expansion solution that minimizes design complexity and maximizes reliability.
