LTM2884CY#PBF

Overview

The LTM2884CY#PBF is a complete galvanically isolated USB 2.0 compatible μModule transceiver manufactured by Analog Devices Inc. It integrates an upstream supply that powers both sides of the interface, eliminating the need for separate isolated power supplies. The device supports Full Speed (FS) data rates compliant with USB 2.0 standards. It operates within a supply voltage range of 4.4 V to 36 V and draws a typical operating current of 5 mA. The component is housed in a BGA-24 package suitable for surface mount installation.

Feature Summary

• Integrates a high-efficiency step-down converter to provide isolated power for both sides of the interface
• Provides complete galvanic isolation between the host and peripheral sides of the USB connection
• Functions as a self-contained μModule transceiver compliant with USB 2.0 specifications

Applications

• Industrial systems requiring isolated USB communication
• Medical equipment needing galvanic separation for safety compliance
• Automotive diagnostic interfaces

Procurement Notes

Verify availability status directly with authorized distributors, as this part may be subject to limited supply or factory special order constraints. Confirm RoHS compliance details and moisture sensitivity levels prior to procurement. Ensure the specific suffix matches design requirements without assuming functional changes based on packaging alone.

Selection Notes

Select this component when a compact, integrated solution for isolated USB connectivity is required. It simplifies design by combining the transceiver and isolated power generation into a single module. Consider the BGA-24 footprint and thermal management capabilities during PCB layout. Verify that the input voltage range aligns with the system's upstream power supply capabilities.

Part Context

This part belongs to the LTM2884 series of isolated USB transceivers from Analog Devices. It is designed to replace discrete isolation components, reducing board space and complexity.
