ADUM3220WARZ

Isolators - Gate Drivers Overview

The ADUM3220WARZ is a dual-channel, current-based isolated gate driver utilizing Analog Devices iCoupler technology. It provides galvanic isolation between control and power stages with a peak output current of 4 A per channel. The device features a nominal undervoltage lockout (UVLO) threshold of 4.1 V. It operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -40°C to +125°C. Key timing parameters include rise and fall times of 22 ns. The component is housed in an SOIC-8 package and holds AEC-Q100 qualification for automotive reliability.

Isolators - Gate Drivers Feature Summary

• Dual-channel architecture providing independent high-current drive for two isolated outputs
• iCoupler technology enabling robust galvanic isolation without magnetic components
• AEC-Q100 qualification ensuring suitability for demanding automotive environments

Isolators - Gate Drivers Applications

• Isolated gate driving for IGBTs and MOSFETs in motor drives
• Power conversion systems requiring high-voltage isolation
• Automotive power electronics and electric vehicle inverters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix WARZ corresponds to the tube packaging variant rather than reel configurations. Confirm that the 4.1 V UVLO specification aligns with the target application requirements. Ensure compatibility with the SOIC-8 footprint during PCB layout. Cross-reference the AEC-Q100 status if automotive compliance is mandatory for the end product.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation with 4 A peak drive capability is required. The 4.1 V UVLO setting suits applications where lower turn-on thresholds are acceptable. Consider the 22 ns propagation delay for switching frequency limitations. The wide operating temperature range supports harsh environment deployments compared to commercial-grade alternatives.

Isolators - Gate Drivers Part Context

This part belongs to the ADuM3220 series of isolated gate drivers. It shares the same core topology as the ADUM3220BRZ but differs in the UVLO threshold specification. The series leverages silicon-based isolation technology to replace traditional optocouplers in high-performance power management designs.

Isolators - Gate Drivers Replacement Considerations

The ADUM3220BRZ serves as a functional alternative within the same family, offering identical drive strength and timing characteristics but with a higher nominal UVLO threshold of 7 V.
