ADUM341E1BRWZ

Overview

The ADUM341E1BRWZ is a quad-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features a 16-SOIC package with a 7.50mm width. The device supports a maximum data rate of 150Mbps and offers a 5700Vrms isolation voltage rating. It operates on supply voltages ranging from 2.25V to 5.5V. Key electrical parameters include a typical propagation delay of 6.2ns, a maximum of 10ns, and a pulse width distortion of less than 3ns. The component provides three unidirectional channels in one direction and one in the reverse, with a fault-safe high output configuration.

Feature Summary

• Integrates four independent data channels using iCoupler magnetic coupling technology for robust signal transmission.
• Provides enhanced safety certification including UL 5700VRMS and VDE compliance for industrial applications.
• Features fault-safe high output logic to ensure predictable states during power loss or input failure.
• Supports bidirectional level shifting between 2.25V and 5.5V domains across the isolation barrier.

Applications

• Isolation of Serial Peripheral Interface (SPI) communication lines
• Protection of Controller Area Network (CAN) and CAN FD bus interfaces
• Signal isolation for RS-485 transceivers in industrial networks
• Gate drive signal isolation for PWM controllers in motor drives

Procurement Notes

Verify the specific suffix 'BRWZ' corresponds to the SOIC-16 package and reel/tray availability as required by your assembly process. Confirm that the 'E1' designation matches the necessary fault-safe high output requirement for your circuit design. Ensure the AEC-Q100 qualification status aligns with automotive grade requirements if applicable. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and recommended operating conditions before finalizing orders.

Selection Notes

Select this component when high-speed data rates up to 150Mbps are required alongside strong common-mode transient immunity. The fault-safe high feature is critical for systems requiring safe default states upon isolation failure. Consider the 16-SOIC footprint constraints and thermal dissipation capabilities within the PCB layout. This part is suitable for applications demanding certified isolation ratings and low dynamic power consumption at moderate data rates.

Part Context

This device belongs to the ADuM34xE family of quad-channel digital isolators. It shares architectural similarities with the ADUM340E and ADUM342E but differs in channel configuration and fault-safe logic options. The E1 variant specifically denotes the fault-safe high output characteristic, distinguishing it from other series members with different logic defaults or channel arrangements.

Replacement Considerations

Public confirmed substitute part numbers include ADUM341E0WBRWZ and ADUM341E1WBRWZ. Verify that alternative suffixes match the required packaging format and specific fault-safe logic levels. Ensure any replacement maintains the same 5700Vrms isolation rating and 150Mbps data speed specifications.

FAQ

What is the fault-safe output state of the ADUM341E1BRWZ?

The 'E1' suffix indicates a fault-safe high output configuration, meaning the outputs transition to a high logic state if the input power is removed or the device fails.

Does this isolator support CAN FD communication?

Yes, the device supports data rates up to 150Mbps, which is sufficient for CAN FD (Controller Area Network Flexible Data-rate) applications.

What is the maximum common-mode transient immunity?

The device typically offers a common-mode transient immunity of 180kV/µs, ensuring reliable operation in noisy environments.
