ADUM1301BRW-RL

Overview

The ADUM1301BRW-RL is a triple-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. The device provides 2500 Vrms isolation voltage with a common-mode transient immunity of 25 kV/µs. Key electrical parameters include a maximum propagation delay of 50 ns, typical rise/fall times of 3 ns, and a pulse width distortion of 100 ns. It functions in temperatures from -40°C to +105°C and draws 43 mA of operating current.

Feature Summary

• Triple-channel bidirectional signal isolation using proprietary iCoupler magnetic coupling technology
• High-speed data transmission capability supporting rates up to 90 Mb/s
• Robust noise immunity characterized by 25 kV/µs common-mode transient rejection
• Wide operational temperature range suitable for industrial environments

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal interfaces needing high safety isolation
• Power electronics gate drive circuits for motor control
• Instrumentation and measurement devices with noisy ground potentials

Procurement Notes

This specific part number (ADUM1301BRW-RL) is officially listed as obsolete and no longer manufactured by Analog Devices Inc. Procurement should focus on verified active substitutes such as the ADUM1301BRWZ-RL. Buyers must confirm component authenticity through authorized channels due to the discontinued status. Verify RoHS compliance and package integrity upon receipt, as legacy stock may vary in condition.

Selection Notes

Select this component when triple-channel isolation is required with high-speed performance up to 90 Mb/s. The 16-SOIC package offers a compact footprint for surface-mount assembly. Ensure the application demands 2500 Vrms isolation and operates within the 2.7 V to 5.5 V supply range. Consider the ADUM1301BRWZ-RL as the direct modern equivalent if new production is needed, as it maintains similar specifications while being currently available.

Part Context

The ADUM1301BRW-RL belongs to the ADuM1300/ADuM1301 series of digital isolators from Analog Devices. These devices leverage iCoupler technology to provide isolation without traditional transformers or optocouplers. The series is designed for applications requiring reliable signal transmission across isolated boundaries in noisy electrical environments, serving as a critical interface between low-voltage logic and higher-voltage power stages.

Replacement Considerations

The ADUM1301BRWZ-RL is confirmed as a direct substitute. It retains the same triple-channel configuration, 16-SOIC package, and core electrical characteristics. Engineers should verify pin compatibility and thermal requirements during transition, as the Z-suffix version represents the updated manufacturing revision of the obsolete BRW-RL part.
