LTM2810HY-I#PBF

Overview

The LTM2810HY-I#PBF is a complete galvanic digital isolator from Analog Devices, designed for I²C communication. It features six channels with 7500Vrms isolation and a common mode transient immunity of 50kV/µs. The device supports data rates up to 400kHz and has a maximum propagation delay of 500ns. It operates on separate 3V to 5.5V supplies for each side, allowing flexible logic interfacing from 1.62V to 5.5V. The component is housed in a 36-lead LQFN package (6mm × 4mm) and functions within a temperature range of 0°C to 70°C.

Feature Summary

• Integrated transformer driver with isolated side LDO for self-contained power regulation
• High common mode transient immunity enabling uninterrupted communication during large transients
• Flexible logic supply pins supporting independent voltage levels from 1.62V to 5.5V

Applications

• Electric Vehicle and Hybrid Electric Vehicle systems
• Industrial automation systems
• Metering applications

Procurement Notes

Verify the suffix 'I' confirms I²C compatibility and 'H' indicates the extended temperature grade. Ensure the '#PBF' designation matches lead-free RoHS compliance requirements. Confirm the specific package variant corresponds to the 36-lead LQFN form factor. Cross-reference the manufacturer's latest documentation to validate current production status and any potential pinout revisions.

Selection Notes

Select this component when high isolation voltage and robust transient immunity are required for I²C buses. It is suitable for systems with different ground potentials where external components must be minimized. Consider the unidirectional channel configuration and master-mode-only specifications. Evaluate thermal management needs given the compact package dimensions and operating temperature range.
