ADUM3223CRZ-RL7

Isolators - Gate Drivers Overview

The ADUM3223CRZ-RL7 is a galvanically isolated precision half-bridge driver manufactured by Analog Devices Inc. It operates within a supply voltage range of 3.3 V to 5 V and delivers an output current capability of 2.3 mA. The device utilizes a SOIC-16 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C. Key timing characteristics include rise and fall times of 12 ns, ensuring precise signal transmission across the isolation barrier for high-speed switching applications.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between input control signals and power stage outputs
• Delivers precise half-bridge driving functionality with defined propagation delay
• Supports wide operating temperature ranges suitable for industrial environments

Isolators - Gate Drivers Applications

• Isolated gate driving for power MOSFETs and IGBTs in motor drives
• Power supply control circuits requiring signal isolation
• Industrial automation systems with high-voltage isolation requirements

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the CRZ variant corresponds to the 3.3V–5V supply range rather than the BRZ high-voltage version. Check current availability status as distribution may be limited or subject to allocation. Ensure compatibility with SOIC-16 footprint during procurement planning.

Isolators - Gate Drivers Selection Notes

Select this component when low-voltage operation (3.3V–5V) is required for the isolated side. Compare against the ADUM3223BRZ if higher supply voltages up to 18V are needed. Consider the 2.3 mA output current limit for driving smaller gate charges. Verify thermal performance within the specified -40°C to +125°C range for the target application environment.

Isolators - Gate Drivers Part Context

This part belongs to the ADUM3223 series of digital isolators combined with gate drivers. It integrates capacitive sensing technology for isolation. The family includes variants like ADUM3223BRZ for higher voltage applications. It serves as a bridge between low-voltage logic and high-power switching stages.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other ADUM3223 variants such as ADUM3223BRZ for different voltage levels. Cross-reference with similar isolated half-bridge drivers from other manufacturers only if pinout and electrical specifications match exactly.
