FSUSB30BQX

Analog Switches - Special Purpose Overview

The onsemi FSUSB30BQX is a low-power, dual-port high-speed USB 2.0 switch supporting data rates up to 480 Mbps. Designed for surface-mount installation, it operates within a supply voltage range of 2.7V to 5.5V and functions reliably across an ambient temperature range of -40°C to +85°C. The device integrates two independent bidirectional switches, enabling flexible signal routing for USB host and peripheral connections while maintaining minimal power consumption during standby modes.

Analog Switches - Special Purpose Feature Summary

• Dual-port architecture providing independent control over two USB 2.0 channels
• Low-power design optimized for battery-operated mobile devices
• Bidirectional signal switching capability for host and peripheral interfaces

Analog Switches - Special Purpose Applications

• Mobile phones and smartphones
• Personal digital assistants (PDAs)
• Portable media players

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'QX' against the manufacturer's current ordering guide to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives by checking the latest datasheet documentation. Confirm that the component meets AEC-Q100 requirements if automotive qualification is necessary for the target application environment.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring isolated USB 2.0 ports with low quiescent current. It serves as a suitable alternative to single-port switches in applications needing simultaneous connection management. Evaluate board space constraints against the available package options to ensure compatibility with the chosen footprint and assembly process.

Analog Switches - Special Purpose Part Context

This part belongs to the FSUSB30 series of USB switches from onsemi, formerly Fairchild Semiconductor. The series includes variants such as FSUSB30 and FSUSB31, differing primarily in port count and pin configuration. These components are widely used in portable electronics to manage USB connectivity without significant power penalty.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes include the FSUSB30 and FSUSB31 models from onsemi. Verify pin-to-pin compatibility and electrical characteristics before substitution. Other manufacturers may offer equivalent USB 2.0 switches, but functional equivalence must be confirmed through detailed parameter comparison.
