LTM2884HY#PBF

Overview

The LTM2884HY#PBF is a complete galvanically isolated USB 2.0 compatible μModule transceiver manufactured by Analog Devices Inc. It integrates a high-efficiency buck converter, a USB emulator, and USB protection switches within a single package. The device supports data rates up to 12 Mb/s with bidirectional communication channels. It provides 2500Vrms isolation for one minute and features a common-mode transient immunity of 30kV/µs. The component operates with an upstream supply that powers both sides of the interface, eliminating the need for separate isolated power sources.

Feature Summary

• Integrates a high-efficiency step-down converter and USB host charger emulator
• Provides galvanic isolation between upstream and downstream interfaces
• Includes high-bandwidth USB protection switches for signal integrity

Applications

• Industrial automation systems requiring isolated USB connectivity
• Medical equipment needing compliant galvanic separation
• Test and measurement instruments with isolated host ports

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm isolation voltage ratings and pinout configurations. Ensure compatibility with required USB 2.0 signaling standards and check for any recent product change notices affecting electrical characteristics or packaging specifications before finalizing procurement.

Selection Notes

Select this component when a compact solution combining power conversion and isolated USB communication is required. It is suitable for designs where space constraints prevent using discrete isolators and external power supplies. Verify that the input voltage range matches the system's available power rails and that the thermal performance meets the application's operating conditions.

Part Context

This part belongs to the LTM2884 series of isolated USB transceivers from Analog Devices. It represents a micromodule solution designed to simplify the implementation of isolated USB interfaces in harsh environments. The series focuses on providing robust protection and reliable data transmission across isolation barriers without complex external circuitry.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference isolation voltage ratings and package dimensions to ensure mechanical and electrical compatibility with existing board layouts.
