ADUM3301WARWZ-RL

Overview

The ADUM3301WARWZ-RL is a three-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features bidirectional data channels with a maximum data rate of 90 Mb/s and an insulation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, consuming typical working power currents of 108 mA. It exhibits a propagation delay of 32 ns and supports pulse widths up to 100 ns. Designed for automotive applications, it holds AEC-Q100 qualification and functions reliably across an operating temperature range of -40°C to +105°C in a 16-SOIC package.

Feature Summary

• Provides galvanic isolation via magnetic coupling for robust noise immunity
• Supports bidirectional communication across all three independent channels
• Qualified for automotive environments under AEC-Q100 standards
• Ensures high common-mode transient immunity for reliable operation

Applications

• Automotive battery management systems
• Industrial motor control interfaces
• Inverter gate drive circuits

Procurement Notes

Verify the specific suffix WARWZ-RL against official Analog Devices documentation to confirm automotive grade status and reel packaging specifications. Ensure compatibility with existing board layouts regarding the 16-SOIC footprint and thermal requirements. Cross-reference the datasheet for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when bidirectional isolation is required for automotive or industrial applications demanding high reliability. The 90 Mb/s data rate suits moderate-speed communication needs, while the wide operating temperature range ensures stability in harsh environments. Consider the power consumption profile relative to system thermal constraints and verify that the 2500 Vrms insulation rating meets safety compliance requirements for the target application.

Part Context

This part belongs to the ADUM3301 series of three-channel digital isolators. It shares the SOIC-16 package form factor with other variants but differs in channel directionality and speed capabilities. The WBRWZ-RL variant offers unidirectional channels at lower speeds, whereas this model provides bidirectional functionality optimized for automotive use cases requiring robust signal integrity.

Replacement Considerations

ADUM3301WBRWZ-RL serves as a functional substitute offering similar isolation characteristics but with unidirectional channels and reduced data rates.
