LTM2883HY-5I#PBF

Overview

The LTM2883HY-5I#PBF is a complete current digital µModule isolator from Analog Devices Inc., housed in a BGA-32 package. It integrates an isolated DC/DC converter powered by a single 3.3V or 5V supply to energize both sides of the interface. The device supports SPI, Digital, or I2C protocols with data rates up to 20 Mb/s and offers 6 channels. Key electrical parameters include an insulation voltage of 2500 Vrms, a maximum operating voltage of 5.5 V, and an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates an isolated DC/DC converter requiring no external components for power generation on both sides of the isolation barrier.
• Supports multiple communication protocols including SPI, Digital, and I2C interfaces within a single compact module.
• Provides adjustable regulated power outputs, specifically ±12.5V and 5V, to accommodate various interface requirements.

Applications

• Isolating SPI-based sensor interfaces in industrial automation systems
• Protecting I2C bus connections in medical equipment against high voltage transients
• Digital signal isolation in noisy factory floor environments

Procurement Notes

Verify the specific suffix (HY-5I) matches the required temperature grade and pinout configuration. Confirm that the BGA-32 package compatibility aligns with your PCB footprint design. Ensure the selected variant meets the necessary insulation voltage ratings for your safety standards. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential obsolescence notices.

Selection Notes

Select this component when a compact solution is needed for isolating digital interfaces without managing external isolated power supplies. It is suitable for applications requiring bidirectional or unidirectional data transfer at speeds up to 20 Mb/s. Consider the integrated power regulation capabilities if space for discrete magnetics is limited. Verify that the 2500 Vrms insulation rating satisfies the system's isolation requirements.

Part Context

This part belongs to the LTM2883 series of µModule isolators designed by Analog Devices. These devices consolidate complex isolation circuitry into a single package, simplifying board layout and reducing component count compared to traditional discrete isolator solutions. The series targets high-reliability applications where space constraints and electromagnetic interference are critical concerns.
