MAX4984EEVB+

Analog Switches - Special Purpose Overview

The MAX4984EEVB+ is a high-speed USB 2.0 switch IC manufactured by Analog Devices Inc./Maxim Integrated, designed for portable applications requiring robust ESD protection. It features a single DPDT switch configuration housed in a compact 10-UTQFN package measuring 1.4x1.8mm. The device operates within a supply voltage range of 2.8V to 5.5V and draws only 3µA of quiescent current. Key electrical parameters include a maximum on-resistance of 10 Ohms, a -3dB bandwidth of 950MHz, and a maximum turn-on time of 100µs with a turn-off time of 5µs. It supports data rates up to 480Mbps and functions reliably across an extended temperature range from -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Provides ±15kV Human Body Model and ±15kV IEC 61000-4-2 Air Gap ESD protection on common terminals without external components.
• Supports full High-Speed USB 2.0 signaling at 480Mbps alongside Full-Speed (12Mbps) and Low-Speed (1.5Mbps) modes.
• Features ultra-low power consumption with 3µA shutdown current, enabling significant battery life extension in portable devices.

Analog Switches - Special Purpose Applications

• Portable media players and digital audio players
• Mobile phones and smartphones
• Personal Digital Assistants (PDAs)
• Digital cameras and camcorders

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'EEVB+' against the official Analog Devices datasheet to confirm the tape-and-reel packaging and lead-free status. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance and REACH status before finalizing procurement specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when designing space-constrained portable electronics that require integrated ESD protection for USB ports. The 10-UTQFN package is suitable for tight board layouts. Verify that the 10 Ohm on-resistance meets the signal integrity requirements of your specific USB implementation. Consider the 2.8V minimum operating voltage to ensure compatibility with your system's power rail.

Analog Switches - Special Purpose Part Context

The MAX4984E belongs to the Maxim Integrated family of high-speed USB switches designed for mobile consumer electronics. It is functionally similar to the MAX4983E but differs in channel configuration. This series addresses the need for small form factors and high reliability in handheld devices where external protection components are impractical due to size constraints.

Analog Switches - Special Purpose Replacement Considerations

The MAX4983EEVB+ is a related device within the same product family. Verify pinout compatibility and channel configuration differences before substitution. Consult the official Analog Devices cross-reference guide for any other qualified replacements or updated versions of this component.
