MCHPUSB2422T-I/MJ
Overview
The USB2422T-I/MJ is an industrial-grade, high-speed USB 2.0 hub controller designed to expand a single USB port into two downstream ports. It features a compact 4x4 mm 24-QFN package and supports advanced power management with low standby current of 425uA. This controller is engineered for applications requiring reliable USB connectivity in harsh environments with an operating temperature range of -40C to 85C.
Why Choose This Part
The device features MultiTRAK technology for high-performance concurrent data transfers and supports configuration via SMBus or external EEPROM. It is highly power-efficient with a supply voltage of 3.3V and integrated 1.8V regulators to simplify PCB design. Its robust industrial temperature rating and small 24-VFQFN footprint make it ideal for ruggedized electronic assemblies.
Applications
Key Specifications
Getting Started
Implementation requires connecting the 3.3V supply and 24MHz crystal or clock source. Configuration can be handled through hardware strapping pins or by using the SMBus interface for custom PID/VID settings. Ensure proper thermal pad soldering of the 24-QFN package for stability and grounding.
