LTM2883IY-5I#PBF

Overview

The LTM2883IY-5I#PBF is a complete galvanic 6-channel digital isolator module from Analog Devices. It integrates I2C isolation with adjustable regulated power supplies, specifically providing ±12.5V and 5V outputs. The device operates on a single 3.3V or 5V supply and requires no external components. Key electrical specifications include an insulation voltage of 2500Vrms, a channel count of six, and a common-mode transient immunity of 30kV/µs. It supports I2C data rates up to 400kHz and utilizes a 32-ball BGA package.

Feature Summary

• Integrates six isolated channels for I2C communication within a single µModule package
• Includes internal adjustable regulated power supplies delivering ±12.5V and 5V outputs
• Provides high common-mode transient immunity of 30kV/µs for robust signal integrity
• Eliminates the need for external discrete components through complete galvanic isolation

Applications

• Industrial automation systems requiring isolated I2C bus connections
• Medical equipment needing galvanic separation for safety compliance
• Test and measurement instruments utilizing multi-channel isolated interfaces
• Automotive electronics with isolated sensor networks

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status before ordering. Confirm the operating temperature range matches your environmental requirements, as industrial variants exist. Ensure the BGA-32 footprint aligns with your PCB design constraints. Check current availability status as supply may be limited. Validate that the integrated power regulation meets the load requirements of your isolated side circuitry.

Selection Notes

Select this component when a compact solution for isolated I2C communication is required without external magnetics. It is suitable for designs needing integrated isolated power generation alongside signal isolation. Consider the BGA-32 package size against board space limitations. Compare against standard discrete isolators if higher channel counts or different protocols are needed. Ensure the input supply voltage matches the 3.3V or 5V requirement specified in the datasheet.

Part Context

This part belongs to the LTM2883 series of digital isolators from Analog Devices. It is designed to replace traditional transformer-based isolation solutions by integrating magnetic coupling and power conversion into a single micromodule. The series offers various configurations for SPI and I2C protocols with different power output options.

Replacement Considerations

Direct replacements include other LTM2883 variants such as LTM2883HY-5I#PBF for extended temperature ranges. Verify pinout compatibility when substituting with similar µModule isolators from the same family.
