ADUM6421AWBRNZ5

Overview

The ADUM6421AWBRNZ5 is a quad-channel digital isolator utilizing iCoupler technology, featuring an integrated isoPower DC-to-DC converter for isolated power delivery. It provides 5000Vrms isolation voltage and supports data rates up to 100 Mb/s with a propagation delay of 10 ns. The device operates on a single 5V supply (4.5V–5.5V) with a typical current consumption of 9.4 mA. It offers 75kV/µs common-mode transient immunity and is housed in a 28-pin SOIC package. The unit functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a regulated DC-to-DC converter providing isolated power to the secondary side.
• Provides robust galvanic isolation between circuits using silicon dioxide insulation.
• Supports high-speed data transmission with low pulse width distortion.

Applications

• Isolated sensor interfaces
• RS-232 transceivers
• Power supply start-up bias circuits
• Gate drives

Procurement Notes

Verify the specific suffix 'WBRNZ5' against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the procurement channel provides valid traceability documentation. Confirm that the reel packaging matches the required quantity specifications for your production line. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing orders.

Selection Notes

Select this component when a quad-channel isolator with integrated isolated power is required to reduce external component count. It is suitable for applications demanding high common-mode transient immunity and low EMI emissions. Consider the 28-SOIC package dimensions for PCB layout constraints. Evaluate the 100 Mb/s data rate capability against system timing requirements.

Part Context

This part belongs to the ADUM6421A family of quad-channel digital isolators from Analog Devices. The series utilizes iCoupler technology to replace traditional magnetic isolators. The ADUM6421AWBRNZ5 variant specifically denotes the tape-and-reel packaging format. It is designed for general-purpose isolation in industrial and automotive environments.

Replacement Considerations

The ADUM6421ABRNZ5 is a documented substitute part number within the same product family. Verify package width and pin configuration compatibility before substitution. Ensure the alternative variant meets the same isolation voltage and data rate specifications.
