FSA3041UMX

Specialized Overview

The FSA3041UMX is a dual high-speed USB 2.0 switch with Mobile High-Definition Link (MHL) support, manufactured by Fairchild Semiconductor. It integrates two independent SPDT switches to manage data lines for USB 2.0 and MHL interfaces. The device operates within a supply voltage range of 2.7V to 5.5V, ensuring compatibility with standard logic levels. It supports data transfer rates up to 480Mbps for USB 2.0 High-Speed mode. The component is housed in a compact UQFN-24 package, designed for surface-mount technology applications requiring minimal board space.

Specialized Feature Summary

• Dual independent signal paths for simultaneous USB and MHL connectivity management
• Integrated ID select functionality for automatic host/device detection
• Low on-resistance channels to preserve signal integrity at high speeds
• Supports flexible power control for connected peripheral devices

Specialized Applications

• Smartphones and tablets requiring dual-port connectivity
• Mobile devices supporting MHL video output via USB interface
• Portable media players with high-speed data transfer needs
• Automotive infotainment systems with mobile device integration

Specialized Procurement Notes

Verify the specific suffix UMX indicates the tape-and-reel packaging configuration when ordering. Confirm that the component meets RoHS compliance requirements for your manufacturing process. Check for obsolescence status as Fairchild Semiconductor products may have transitioned to ON Semiconductor distribution channels. Ensure ESD handling procedures are followed during assembly due to the sensitive nature of high-speed interface circuits.

Specialized Selection Notes

Select this component when dual-channel switching between USB 2.0 and MHL signals is required in a single package. Consider the UQFN-24 footprint constraints against available PCB real estate. Evaluate the 2.7V to 5.5V operating range against your system's power rails. Compare pinout compatibility if replacing existing designs from other manufacturers offering similar dual-switch solutions.

Specialized Part Context

This part belongs to Fairchild's family of high-speed analog switches designed for multimedia interfaces. It complements other models like the FSA3031 by providing integrated ID detection capabilities. The series targets consumer electronics where space efficiency and multi-standard support are critical design parameters for modern mobile hardware architectures.

Specialized Replacement Considerations

Direct substitutes include the TS3USB3031 from Texas Instruments, which offers similar dual USB/MHL switching capabilities. The FSA3031UMX serves as a closely related variant within the same product line. Verify pin-to-pin compatibility before substitution to ensure seamless integration into existing circuit layouts without redesigning the PCB.
