USB2422T-I/MJ

Controllers Overview

The USB2422T-I/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 attachment and downstream devices up to 480 Mb/s. The device operates on a single 3.3 V supply, utilizing internal regulators for 1.2 V core voltage. It features fully integrated USB termination and pull-up/pull-down resistors, ESD protection up to 6 kV, and an on-chip driver for a 24 MHz crystal or external clock. The component supports the USB Battery Charging Specification Revision 1.1 and operates within an industrial temperature range of -40°C to +85°C.

Controllers Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) compared to commercial variants. Confirm package type is 24-pin SQFN (4x4 mm). Ensure RoHS compliance documentation matches current manufacturing standards. Check datasheet revision history for any silicon errata applicable to this part number before finalizing procurement specifications.

Controllers Selection Notes

Select this component for designs requiring a compact, low-pin-count USB 2.0 hub solution. The industrial temperature rating makes it suitable for harsh environments. Verify that the system design accommodates the single 3.3 V power supply requirement and integrates the necessary 24 MHz crystal or clock source. Ensure the application does not require more than two downstream ports or multiple transaction translators.

Controllers Part Context

This part belongs to the Microchip USB2422 series of low-pin-count USB 2.0 hub controllers. It is designed as a cost-effective alternative to larger hub ICs by integrating passive components and reducing external bill-of-materials. The 'MJ' suffix denotes the 24-pin SQFN package, while 'I' specifies the industrial temperature range variant.
