Overview
The UM7222 is a high-speed USB 2.0 (480 Mbps) DPDT analog switch manufactured by Union Semiconductor International Limited. It supports single-supply operation within a voltage range of 1.8V to 4.3V. The device features bidirectional channels designed to maintain signal integrity with minimal attenuation during transmission. Key electrical characteristics include a typical on-resistance of 4.5Ω at 3V, a -3dB bandwidth of 550MHz, and low crosstalk of -41dB at 250MHz. It offers fast switching times with typical turn-on and turn-off delays of 10ns and 22ns respectively. The component operates reliably across an extended temperature range from -40°C to +85°C.
Feature Summary
- Supports high-speed USB 2.0 data rates up to 480 Mbps with bidirectional channel capability for minimal signal loss.
- Provides robust protection against VBUS short circuits to D+/D- lines in both powered and unpowered states.
- Features rail-to-rail input/output operation and break-before-make switching logic to prevent signal interference.
Applications
- Mobile phone peripheral connections
- Computer peripheral routing
- Portable digital devices
Procurement Notes
Verify the specific package variant, such as TQFN or MSOP, when sourcing. Confirm that the supplier provides official datasheets matching the Union Semiconductor part number. Ensure compliance with RoHS standards if required by the manufacturing process. Check for green material certification if environmental regulations apply to the final assembly.
Selection Notes
Select this component for applications requiring reliable USB 2.0 signal routing with low insertion loss. Consider the 1.8V to 4.3V supply range compatibility with system power rails. Evaluate the thermal performance within the -40°C to +85°C operating window. Compare on-resistance and isolation specs against alternative switches like the SGM7222 or DG2722 for circuit optimization.
Part Context
The UM7222 belongs to a family of high-speed analog switches including variants like UM7222A and UM7222MA. These components are designed for portable electronics where space and power efficiency are critical. They serve as direct replacements for similar USB routing switches in consumer hardware designs.
Replacement Considerations
Compatible substitutes include the SGM7222 and Vishay DG2722. Verify pinout compatibility and electrical parameters such as on-resistance and bandwidth before substitution.
