ADUM130D0BRZ

Overview

The ADUM130D0BRZ is a triple-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 3:0 channel isolation with unidirectional data flow. Key electrical parameters include a data rate of 150 Mb/s, insulation voltage of 3000 Vrms, and common-mode transient immunity of 75 kV/µs. The device operates on a supply voltage range of 1.8 V to 5 V, with a maximum power dissipation of 1.64 W. Propagation delay is typically 7.2 ns, with rise/fall times of 2.5 ns. It functions within an operating temperature range of -40°C to +125°C and is housed in a 16-SOIC package.

Feature Summary

• Integrates three independent digital channels for signal isolation using proprietary iCoupler magnetic coupling technology.
• Features input disable functionality to control output states during power-down or fault conditions.
• Provides high robustness against common-mode transients to ensure reliable operation in noisy environments.
• Supports standard logic protocols including SPI communication interfaces.

Applications

• Motor control systems requiring isolated gate drive signals
• Industrial automation equipment with mixed-signal grounding requirements
• Power supply feedback loops needing galvanic isolation

Procurement Notes

Verify the specific suffix (RL7) indicates reel packaging if required by assembly equipment. Confirm current availability status as distribution may vary. Ensure the 16-SOIC footprint matches the PCB design. Check RoHS compliance documentation for regulatory adherence. Validate that the 3000 Vrms rating meets the system's isolation safety standards.

Selection Notes

Select this component when three isolated channels are required in a single package. Consider the 150 Mb/s speed limit for high-frequency applications. Evaluate the 1.8 V to 5 V supply range compatibility with the system logic levels. Assess the thermal performance given the 1.64 W power dissipation capability. Compare the 75 kV/µs CMTI against noise immunity requirements of the target application.

Part Context

This part belongs to the ADuM130 series of triple-channel digital isolators from Analog Devices. It is part of the broader iCoupler family, which replaces traditional optocouplers with integrated transformer technology. The series includes variants like ADUM130E and ADUM131D, differing in insulation ratings or channel configurations. This specific model focuses on general-purpose isolation with robust transient immunity.

Replacement Considerations

Public confirmed substitute part numbers include ADUM130D0BRWZ and ADUM130D0BRWZ-RL. Verify pinout compatibility and insulation voltage ratings before substitution. Ensure the replacement supports the same 16-SOIC package and operational temperature range.
