LTM2883CY-3I#PBF

Overview

The LTM2883CY-3I#PBF is a complete galvanic 6-channel digital µModule isolator manufactured by Analog Devices Inc. It integrates magnetic coupling isolation with adjustable regulated power supplies, providing 12.5V and 5V outputs. The device supports data rates up to 20 Mb/s with an insulation voltage of 2500 Vrms and common-mode transient immunity of 30 kV/µs. Operating on a single 3V to 3.6V logic supply, it features bidirectional or unidirectional channels in a 32-pin BGA package.

Feature Summary

• Integrates six isolated digital channels with integrated DC/DC converters for dual-side power supply
• Provides adjustable regulated output voltages of 12.5V and 5V without external components
• Supports SPI, I2C, and general digital interfaces with high common-mode transient immunity

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment signal interfacing
• Automotive electronic control units
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range operation (0°C to +70°C) as per official documentation. Confirm the 'CY' package code corresponds to the 32-lead BBGA form factor. Ensure compatibility with the required logic supply voltage range of 3V to 3.6V. Check for moisture sensitivity level requirements during assembly. Validate that the integrated power regulation meets the target system's current demands.

Selection Notes

Select this component when a compact solution for multiple isolated digital lines is required alongside integrated power generation. It eliminates the need for external isolated DC/DC converters and discrete isolators. Suitable for designs needing high CMTI and support for various digital protocols like SPI and I2C within a small footprint. Consider the thermal performance of the BGA package under maximum load conditions.

Part Context

Part of the LTM2883 µModule family designed for simplified isolation design. It consolidates complex isolation circuitry into a single module. Similar parts in the series may offer different channel counts or fixed voltage outputs. The LTM2883 specifically addresses applications needing both data isolation and isolated power delivery in a space-constrained environment.

Replacement Considerations

Direct substitutes include other LTM2883 variants with different temperature grades or package options, such as LTM2883CY-5S#PBF. Verify pinout compatibility and electrical specifications before substitution. Alternative solutions may require additional external components if not using a similar µModule architecture.
