Microchip Technology USB2422
The Microchip USB2422 hub is a low-power, single transaction translator, hub controller IC with two downstream ports for embedded USB solutions. The hub controller can attach to an upstream port as a Hi-Speed and Full-Speed hub or as a Full-Speed only hub.GENERAL DESCRIPTION
The 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.FEATURES
● Supports the USB Battery Charging Specification, Revision 1.1● Fully integrated USB termination and pull-up/pulldown resistors
● Supports a single external 3.3 V supply source; internal regulators provide 1.2 V internal core voltage
● On-chip driver for 24 MHz crystal resonator or external 24 MHz clock input
● ESD protection up to 6 kV on all USB pins
● Supports self-powered operation
● The hub contains a built-in default configuration; no external configuration options or components are required
● Downstream ports as non-re...
