ADUM3100BRZ

Overview

The ADUM3100BRZ is a single-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s. The device provides an isolation voltage of 2500 Vrms with a typical propagation delay of 10.5 ns and rise/fall times of 3 ns. It functions in unidirectional mode with a maximum power dissipation of 240 mW and operates across a temperature range of -40°C to +105°C. Packaged in an 8-pin SOIC, it offers high common-mode transient immunity for robust signal transmission.

Feature Summary

• Provides galvanic isolation between logic signals and high-power circuits using magnetic coupling technology
• Ensures enhanced system-level ESD reliability for robust performance in noisy environments
• Supports high-speed data transfer with low propagation delay for precise timing applications

Applications

• Isolated H-bridge drivers for motor control systems
• Power conversion circuits with embedded control interfaces
• Uninterruptible power supplies (UPS) requiring signal isolation

Procurement Notes

Verify the specific suffix BRZ confirms the SOIC-8 package and tube packaging format when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to integration. Ensure the component matches the exact part number to guarantee compatibility with existing design specifications and regulatory requirements.

Selection Notes

Select this component for applications requiring single-channel isolation with high data rates up to 100 Mb/s. It is suitable for designs needing 2500 Vrms isolation in a compact 8-pin SOIC footprint. Consider its unidirectional nature and 3 V to 5.5 V operating range when designing the interface circuitry for low-voltage logic systems.
