The Microchip USB2422 hub is a low-power, single transaction translator, hub controller IC with two downstream ports for embedded USB solutions. The Microchip hub controller can attach to an upstream port as a Hi-Speed and Full-Speed hub or as a Full-Speed only hub. The Microchip hub supports Low-Speed, Full-Speed, and Hi-Speed (when configured as a Hi-Speed hub) downstream devices on the enabled downstream ports.
All required resistors on the USB ports are integrated into the hub. This includes all series termination resistors on D+ and D- pins and all required pull-down and pull-up resistors on D+ and D- pins. The over-current sense inputs for the downstream facing ports have internal pull-up resistors.
The EVB-USB2422 Evaluation Board demonstrates a standalone application for the USB2422 low-power, full-featured, configurable Hi-Speed USB 2.0 compliant hub. The board includes two downstream ports with individual port power control and battery charging support on each port. This evaluation board is designed to support internal default configuration settings as well as custom configuration through...
