USB2422T/MJ

Controllers Overview

The USB2422T/MJ is a low-power, single transaction translator hub controller IC with two downstream ports for embedded USB solutions. It supports Hi-Speed and Full-Speed upstream connections and downstream devices at Low-Speed, Full-Speed, and Hi-Speed. The device integrates all required USB termination resistors and pull-up/pull-down components. It operates on a single external 3.3 V supply, utilizing internal regulators to provide 1.2 V core voltage. Electrical parameters include a data rate of 480 Mb/s, an operating voltage range of 3 V to 3.6 V, and a maximum operating current of 70 mA. The component is housed in a 24-pin SQFN (4x4 mm) package.

• On-chip driver for 24 MHz crystal resonator or external clock input
• ESD protection up to 6 kV on all USB pins

Controllers Applications

• LCD monitors and TVs
• Multi-function USB peripherals
• PC motherboards
• Set-top boxes, DVD players, DVR/PVR
• Printers and scanners

Controllers Procurement Notes

Verify the specific suffix 'MJ' against the manufacturer's official documentation to confirm the commercial temperature range and RoHS compliance status. Ensure that the ordering information matches the exact datasheet revision referenced by the supplier. Confirm that the package type corresponds to the 24-pin SQFN form factor specified in the product identification system.

Controllers Selection Notes

Select this component when a compact, low-pin-count solution is required for expanding USB connectivity in embedded systems. The built-in default configuration eliminates the need for external configuration components, reducing bill-of-materials complexity. Verify that the host system can support the SMBus interface if dynamic configuration beyond the default settings is necessary.

Controllers Part Context

The USB2422T/MJ belongs to the Microchip USB2422 series of USB hub controllers. This family is designed for high-performance, low-power applications requiring minimal footprint. The 'T' indicates tape and reel packaging, while '/MJ' designates the specific package variant and temperature rating. Other variants in the series may offer different temperature ranges or pin configurations.
