MAX22702DAWA+

Isolators - Gate Drivers Overview

The MAX22702DAWA+ is a single-channel isolated gate driver from the MAX22700–MAX22702 family, designed for silicon-carbide (SiC) and gallium nitride (GaN) power devices. It features ultra-high common-mode transient immunity (CMTI) of 300kV/µs typical. The device provides galvanic isolation with a voltage rating of 5000Vrms. It utilizes capacitive coupling for signal transmission and is housed in an 8-SOIC package.

Isolators - Gate Drivers Feature Summary

• Ultra-high common-mode transient immunity suitable for high dv/dt environments
• Galvanic isolation via capacitive coupling technology
• Optimized for driving wide-bandgap power semiconductors

Isolators - Gate Drivers Applications

• Silicon-Carbide (SiC) MOSFET gate driving
• Gallium Nitride (GaN) FET gate driving
• High-frequency isolated power conversion stages

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'DAWA+' against official Analog Devices documentation to confirm pinout and isolation ratings. Ensure compatibility with target SiC/GaN gate charge requirements. Confirm RoHS compliance status through current manufacturer declarations. Validate that the 8-SOIC package matches PCB layout constraints.

Isolators - Gate Drivers Selection Notes

Select this component when high CMTI is critical to prevent false triggering in noisy switching environments. The capacitive coupling interface offers robustness against ground bounce compared to magnetic isolation. Consider the single-channel configuration for half-bridge or synchronous rectifier applications requiring independent control.

Isolators - Gate Drivers Part Context

This part belongs to the MAX2270x family of isolated gate drivers. The family shares core isolation technologies but varies in channel count and specific electrical characteristics. The MAX22702 variant specifically targets applications demanding the highest levels of transient immunity for next-generation power electronics.

Isolators - Gate Drivers Replacement Considerations

Check for direct substitutes within the MAX22700–MAX22702 series. Verify if alternative packages or thermal options are available from the same manufacturer. Cross-reference isolation voltage and CMTI specifications with other industry-standard isolated gate drivers if supply chain constraints exist.
