LTM2810IY-I#PBF

Overview

The LTM2810IY-I#PBF is a complete galvanic digital microModule isolator designed for I2C communication. It integrates six isolated channels with a transformer driver and an isolated LDO, eliminating the need for external components. The device supports input voltages from 3V to 5.5V and logic levels from 1.62V to 5.5V. It provides 7500VRMS isolation with a common mode transient immunity of 50kV/µs. The module operates at speeds up to 400kHz for I2C and functions within a temperature range of -40°C to 125°C.

Feature Summary

• Integrates a transformer driver and isolated LDO for self-contained operation without external components
• Provides high-speed digital isolation compatible with I2C protocols in master mode only
• Features robust common mode transient immunity exceeding 50kV/µs for reliable communication across ground potentials

Applications

• Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) systems
• Industrial automation and control systems
• Precision metering applications requiring galvanic isolation

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm the specific suffix matches the required I2C variant. Check current availability status as supply may be limited. Ensure storage conditions comply with moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this model specifically for I2C master-mode isolation requirements. The LTM2810-S variant is intended for SPI interfaces. Verify that the system voltage ranges align with the 3V to 5.5V supply specification. Consider the BGA-133 package dimensions for PCB layout constraints. Ensure the application does not require slave-mode I2C functionality.

Part Context

This component belongs to the LTM2810 family of digital isolators manufactured by Analog Devices. It utilizes magnetic coupling technology to achieve high-voltage isolation within a compact BGA package. The series is designed to simplify board design by integrating power regulation and signal transmission into a single module.
