ADUM221N0BRWZ-RL

Overview

The ADUM221N0BRWZ-RL is a dual-channel digital isolator from Analog Devices, housed in a 16-pin SOIC package. It provides unidirectional signal isolation with a data rate of 150 Mb/s and an insulation voltage of 5000 Vrms. The device operates on a supply voltage between 3 V and 5.5 V, drawing 800 uA per channel. It features magnetic coupling for isolation and meets AEC-Q100 automotive qualification standards. The component supports an operating temperature range from -40°C to +125°C and includes a reverse channel configuration.

Feature Summary

• Provides robust galvanic isolation using proprietary magnetic coupling technology.
• Supports high-speed unidirectional data transmission at 150 Mb/s.
• Includes a dedicated reverse channel for bidirectional control signals within a unidirectional architecture.
• Automotive qualified under AEC-Q100 standards for reliability.

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial systems needing high common-mode transient immunity
• Power electronics gate drive circuits

Procurement Notes

Verify the specific suffix 'WTRWZ' or 'WSRWZ' against the datasheet to confirm pinout and packaging variations. Confirm AEC-Q100 compliance requirements for your specific application environment. Check current availability status as distribution may be limited. Ensure the SOIC-16 footprint matches your PCB design constraints before ordering.

Selection Notes

Select this component when high-speed unidirectional isolation is required alongside a reverse control path. Compare propagation delay and power consumption against other ADUM series parts if lower latency is needed. Verify that the 5000 Vrms insulation rating meets your safety isolation requirements. Consider the SOIC-16 package size relative to available board space.

Part Context

This part belongs to the ADUM221x family of robust digital isolators. It shares architectural similarities with other ADUM devices but offers specific channel configurations and speed ratings tailored for automotive and industrial applications. The family emphasizes low power consumption and high CMTI performance.

Replacement Considerations

Check ADUM2210WTRWZ-RL for similar specifications. Verify pin compatibility and electrical parameters before substitution.
