ADUM362N0BRQZ

Overview

The ADUM362N0BRQZ is a six-channel digital isolator utilizing Analog Devices iCoupler technology, housed in a 16-lead QSOP package. It provides a 3000 Vrms isolation rating with independent power domains ranging from 2.25 V to 5.5 V on both sides. The device supports data rates up to 150 Mb/s at 5 V operation and features a typical propagation delay of 6.2 ns. It includes a fail-safe low output configuration (N0) and operates within a temperature range of -40°C to +125°C.

Feature Summary

• High common-mode transient immunity of 180 kV/µs for robust noise rejection
• Independent dual-side power supply support enabling voltage translation between logic levels
• Fail-safe low output configuration ensures defined state during input power loss
• Compliance with CISPR 32/EN 55032 Class B limits for electromagnetic interference

Applications

• Isolation of serial peripheral interface (SPI) data converters
• Isolation of RS-485 communication interfaces
• Controller Area Network (CAN FD) industrial fieldbus isolation
• Pulse width modulation (PWM) controller signal isolation

Procurement Notes

Verify the specific suffix 'N0' confirms the fail-safe low output characteristic required for your design. Confirm the 'QZ' designation indicates automotive qualification under AEC-Q100 standards if applicable to your environment. Ensure the QSOP-16 package dimensions match your PCB footprint constraints. Check current availability status as distribution may be limited or subject to factory order requirements.

Selection Notes

Select this component when high-speed SPI or CAN FD isolation is required alongside strict electromagnetic compatibility standards. The 180 kV/µs CMTI rating makes it suitable for noisy industrial environments. The independent power domain feature allows seamless level shifting between different voltage rails without external components. Consider the fail-safe low option if system safety requires a defined low state upon power failure.

Part Context

This part belongs to the ADuM360N/ADuM362N family of six-channel digital isolators based on iCoupler technology. The family utilizes monolithic air-core transformer coupling for data transmission across the isolation barrier. Variants within the series differ primarily by output configuration options, such as fail-safe high or low states, and packaging types like tube or reel.

Replacement Considerations

The ADUM362N1WBRQZ-RL7 serves as a functional substitute within the same family, offering identical electrical specifications but featuring a fail-safe high output configuration instead of low. Verify that the change in default output state does not impact system logic requirements before substitution.
