MCHPUSB2422-I/MJ
Overview
The USB2422-I/MJ is a low-power, industrial-grade USB 2.0 Hi-Speed hub controller designed to expand a single USB port into two downstream ports. It features MultiTRAK technology for high-performance data throughput and is optimized for space-constrained applications with its small 4x4mm QFN footprint. The device supports advanced power management and can be configured via internal default settings or an external SMBus interface.
Why Choose This Part
The controller is highly efficient, drawing only 70mA when operating two Hi-Speed downstream ports and as little as 300uA in standby. Its industrial temperature rating of -40C to +85C makes it suitable for outdoor or factory floor deployments. It also simplifies PCB design by integrating the 1.8V regulator and providing flexible configuration via SMBus or strapped pins.
Applications
Key Specifications
Getting Started
Designers should reference the Microchip EVB-USB2422 evaluation board for validated PCB layout patterns and signal integrity strategies. Configuration can be handled through hardware strapping pins for standard bus-powered or self-powered modes, or via an external microcontroller using the SMBus interface for custom PID/VID settings. Ensure the 24-QFN exposed pad is properly soldered to a ground plane for thermal dissipation and electrical performance.
