LTM2889HY-3#PBF

Specialized ICS Overview

The LTM2889HY-3#PBF is a complete galvanically-isolated Controller Area Network (CAN) µModule transceiver manufactured by Analog Devices Inc. It integrates an isolated DC/DC converter, eliminating the need for external components to power both sides of the interface. The device supports data rates up to 4 Mbps with Flexible Data Rate (CAN FD) capability and provides 2500VRMS isolation per UL1577. Designed for automotive temperature ranges (-40°C to 125°C), it accepts a 3V to 3.6V input supply and offers high common mode transient immunity exceeding 30kV/µs.

Specialized ICS Feature Summary

• Integrated Isolated DC/DC Converter: Powers both logic and bus sides from a single supply without external components.
• High Isolation Rating: Provides 2500VRMS isolation barrier compliant with UL1577 standards.
• Automotive Grade: Operates reliably within the -40°C to 125°C ambient temperature range.
• Enhanced ESD Protection: Withstands ±25kV HBM on interface pins and ±10kV across the isolation barrier.

Specialized ICS Applications

• Isolated CAN Bus Interface
• Industrial Networks
• DeviceNet Applications

Specialized ICS Procurement Notes

Verify the specific suffix 'H' confirms the automotive temperature grade (-40°C to 125°C) and '3' indicates the 3V input voltage range. Confirm the '#PBF' designation ensures lead-free compliance. Check current availability status as distribution may vary by region.

Specialized ICS Selection Notes

Select this part when an integrated isolated CAN solution is required for automotive or harsh industrial environments. Ensure the system operates within the 3V to 3.6V input range. Consider the 32-BGA package constraints and moisture sensitivity levels during PCB assembly planning.

Specialized ICS Part Context

This component belongs to the LTM2889 family of isolated CAN transceivers. The 'HY' designation specifies the BGA package type and automotive temperature rating, while the '-3' suffix denotes compatibility with 3V logic supplies. It serves as a robust interface for breaking ground loops in noisy electrical environments.

Specialized ICS Replacement Considerations

Direct substitutes include other LTM2889 variants such as LTM2889IY-3#PBF for industrial temperature ranges or LTM2889CY-3#PBF for commercial ranges. Verify pinout and thermal characteristics match before substitution.
