ADUM3223BRZ

Isolators - Gate Drivers Overview

The ADUM3223BRZ is a current-isolated precision half-bridge gate driver manufactured by Analog Devices Inc. It utilizes iCoupler technology to provide independent high-side and low-side outputs within a narrow-body 16-lead SOIC package. The device offers 3000 Vrms isolation between input and each output, with a peak voltage difference of up to 800V between high-side and low-side channels. It supports an input voltage range of 3.0V to 5.5V and delivers a continuous output current of 4A. Key timing parameters include rise and fall times of 12 ns. The operating temperature range spans from -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• Provides true galvanic isolation using integrated magnetic coupling technology instead of traditional optical or transformer methods.
• Delivers independent high-side and low-side drive signals suitable for half-bridge configurations.
• Supports negative voltage switching on the low side relative to the input ground.

Isolators - Gate Drivers Applications

• Driving power MOSFETs in isolated half-bridge circuits
• Gate driving for IGBT modules requiring high common-mode transient immunity
• Industrial motor control systems with isolated power stages

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix (e.g., BRZ) against the latest manufacturer datasheet to confirm package width and isolation rating. Confirm RoHS compliance status and lead-free soldering compatibility with your assembly process. Check for any recent product change notices that may affect pinout or electrical characteristics before finalizing design-in.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching with minimal propagation delay skew is required in isolated environments. The 12 ns rise/fall time supports higher frequency operation compared to slower optocouplers. Ensure the PCB layout accommodates the 16-SOIC footprint and maintains adequate creepage distances for the 3000 Vrms isolation requirement.

Isolators - Gate Drivers Part Context

This part belongs to the ADUM3223 series of iCoupler gate drivers. It is distinct from non-isolated drivers and other isolated variants like the ADUM41xx series which may offer different isolation ratings or additional features such as fault detection. The BRZ designation indicates a specific package variant within the broader ADUM3223 family.
