FUSB252UMX

Analog Switches - Special Purpose Overview

The FUSB252UMX is a USB Type-C CC switch IC manufactured by onsemi, designed for port protection and signal routing. It features two independent SPST switches with a maximum on-resistance of 480 mΩ and a -3dB bandwidth of 1 GHz. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a maximum DC switch current of 1 A. Key timing parameters include a maximum run time of 25 ms and an idle time of 400 ns. It functions in temperatures from -40°C to +85°C and is housed in a 16-UMLP (1.8x2.6 mm) package.

Analog Switches - Special Purpose Feature Summary

• Supports USB Type-C CC line switching with break-before-make functionality
• Provides dual-channel protection for D+ and D- signals
• Operates with low quiescent current for power efficiency

Analog Switches - Special Purpose Applications

• USB Type-C port protection circuits
• D+ and D- signal routing in host or device interfaces

Analog Switches - Special Purpose Procurement Notes

Verify component status as the FUSB252UMX is listed as End-of-Life (EOL) with obsolescence effective July 1, 2023. Confirm availability through authorized distributors for remaining stock or consider alternative sourcing strategies. Ensure compliance with RoHS3 and REACH requirements as documented in the manufacturer's material declaration.

Analog Switches - Special Purpose Selection Notes

Select this component for designs requiring high-speed USB 2.0 signal integrity with low insertion loss. The 1 GHz bandwidth supports High-Speed USB data rates effectively. Evaluate the 480 mΩ on-resistance impact on signal attenuation for specific trace lengths. The compact 16-UMLP package suits space-constrained mobile and automotive PCB layouts.

Analog Switches - Special Purpose Part Context

The FUSB252 belongs to onsemi’s USB Type-C solutions portfolio, specifically addressing port protection needs. It complements controllers like the FUSB307B by handling physical layer switching. This series integrates protection mechanisms directly into the signal path, reducing external component count compared to discrete diode-based solutions.
