General Description

The Microchip USB2422 hub is a low-power, single

transaction translator, hub controller IC with two down-

stream 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. 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 resis-

tors 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/pull-

down resistors

• Supports a single external 3.3 V supply source;

internal regulators provide 1.2 V internal core volt-

age

• 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-removable ports

• Downstream port power control and over-current

detection on an individual or ganged basis

• Supports compound devices on a port-by-port

basis

• 24-pin SQFN (4x4 mm), RoHS-compliant pack-

age

• Commercial temperature range support:

0ºC to +70ºC

• Industrial temperature range support:

-40ºC to +85ºC

Highlights

• High performance, low-power, small footprint hub

controller IC with two downstream ports

• Fully compliant with the USB 2.0 Specification

• Optimized for minimal bill-of-materials and low-

cost designs

Applications

• LCD monitors and TVs

• Multi-function USB peripherals

• PC motherboards

• Set-top boxes, DVD players, DVR/PVR

• Printers and scanners

• PC media drive bay

• Portable hub boxes

• Mobile PC docking

• Embedded systems

• Gaming consoles

• Cable/DSL modems

• HDD enclosures

• KVM switches

• Server front panels

• Point-of-Sale (POS) systems

• IP telephony

• Automobile/home audio systems

• Thin client terminals
