ADUM4402WARWZ

Overview

The ADUM4402WARWZ is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. The device provides an insulation voltage of 5000 Vrms and features enhanced ESD protection. It is housed in a 16-lead SOIC-W package and is qualified under the AEC-Q100 standard for automotive applications. The typical propagation delay is 32 ns, with rise and fall times of approximately 3 ns. Operating temperatures range from -40°C to +105°C.

Feature Summary

• Quad-channel unidirectional signal isolation using magnetic coupling technology
• Enhanced ESD protection capabilities for robust signal integrity
• AEC-Q100 qualification suitable for demanding automotive environments

Applications

• Automotive electronic control units requiring high-reliability isolation
• Industrial communication interfaces needing galvanic isolation
• Power electronics systems with isolated gate drive signals

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential supply constraints. Confirm that the specific WARWZ suffix corresponds to the wide-body SOIC package and AEC-Q100 automotive qualification. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified in the official datasheet before integration into production lines.

Selection Notes

Select this component when four independent isolated channels are required with high common-mode transient immunity. The wide-body SOIC-W package facilitates thermal management and creepage distance requirements. Consider the 90 Mb/s data rate limit and 32 ns propagation delay for timing-critical designs. Verify that the 5000 Vrms insulation rating meets the system's safety isolation standards.

Part Context

This part belongs to the ADUM4402 series of digital isolators. It shares core specifications with other variants like the ADUM4402BRIZ but differs in packaging and qualification. The WARWZ variant specifically targets automotive markets with its AEC-Q100 certification and wider body package, distinguishing it from standard industrial versions.

Replacement Considerations

Direct substitutes include other ADUM4402 variants such as ADUM4402ARIZ or ADUM4402CRIZ, provided package and qualification differences are acceptable. Cross-reference pinouts and electrical parameters carefully to ensure functional equivalence in existing designs.
