LTM2883HY-3I#PBF

Overview

The LTM2883HY-3I#PBF is a µModule digital isolator designed for SPI, digital, or I²C interfaces. It integrates magnetic coupling isolation with adjustable regulated power supplies providing ±12.5V and 5V outputs. The device operates within a supply voltage range of 3 V to 3.6 V and supports data rates up to 20 Mb/s. It features bidirectional and unidirectional channel configurations with a 2500 Vrms insulation voltage and high common-mode transient immunity of 30 kV/µs. Packaged in a 32-ball BGA, it functions across an industrial temperature range of -40°C to +105°C.

Feature Summary

• Integrates isolated interface logic with on-chip adjustable regulated power generation
• Utilizes magnetic coupling technology for galvanic isolation
• Supports multiple communication protocols including SPI, I²C, and general digital signals

Applications

• Industrial process control systems requiring isolated communication
• Medical equipment signal isolation
• Automotive electronic control unit interfaces

Procurement Notes

Verify the specific suffix 'HY-3I' against official Analog Devices documentation to confirm package type, temperature grade, and internal configuration. Ensure compatibility with the DC1748A evaluation board if hardware validation is required. Confirm RoHS compliance status through current manufacturer declarations.

Selection Notes

Select this component when a compact solution combining isolation and power regulation is necessary. It eliminates external transformer and regulator design complexity. Verify that the 2500 Vrms isolation rating meets system safety requirements and that the 32-ball BGA footprint fits the PCB layout constraints.

Part Context

This part belongs to the LTM2883 series of µModule isolators from Analog Devices. It is distinct from the LTM2882 RS-232 transceivers and the LTM2892 variant which offers higher 3500 Vrms isolation. The HY-3I designation indicates specific thermal and packaging characteristics within this product family.

Replacement Considerations

The LTM2883CY-5S#PBF serves as a related alternative within the same series but differs in package and voltage specifications. Cross-reference datasheets to ensure pinout and electrical parameter compatibility before substitution.
