MAX22700DASA+T

Isolators - Gate Drivers Overview

The MAX22700DASA+T is a single-channel isolated gate driver designed for silicon carbide (SiC) and gallium nitride (GaN) transistors. It features ultra-high common-mode transient immunity of 300kV/μs typical. The device supports a minimum pulse width of 20ns with maximum pulse width distortion of 2ns. Transmission delay matches within 2ns at +25°C and 5ns across the -40°C to +125°C range. It offers integrated digital isolation rated for 3kVRMS continuous voltage. The part operates in an 8-pin narrow SOIC package with 4mm creepage and clearance.

Isolators - Gate Drivers Feature Summary

• Ultra-high common-mode transient immunity ensures reliable signal transmission in high-noise environments
• Integrated digital isolation provides electrical separation between power domains
• Precise transmission delay matching minimizes dead-time requirements in power stages
• Optimized output drive characteristics support wide-bandgap transistor switching

Isolators - Gate Drivers Applications

• Silicon carbide (SiC) transistor gate driving in inverters
• Gallium nitride (GaN) transistor gate driving in motor control systems
• High-efficiency power conversion topologies requiring isolated drive signals

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm the D version denotes differential input configuration as required by the system design. Ensure the 8-SOIC package dimensions align with the PCB layout constraints. Check for RoHS compliance status relevant to the manufacturing region. Validate that the 3kVRMS isolation rating meets the safety standards of the target application.

Isolators - Gate Drivers Selection Notes

Select this component when driving SiC or GaN devices requiring high CMTI to prevent false triggering. The differential input option suits noisy environments where single-ended inputs may fail. Consider the 2ns delay matching for applications demanding tight timing synchronization between half-bridge legs. The 8-pin SOIC package offers a compact solution for space-constrained designs. Evaluate the thermal performance within the specified operating temperature range.

Isolators - Gate Drivers Part Context

This device belongs to the MAX22700–MAX22702 family of isolated gate drivers. The family shares core isolation technology but varies in output configurations such as Miller clamp or adjustable UVLO. The MAX22700 variant specifically lacks these additional features, focusing on basic high-speed isolation. All members utilize Maxim's proprietary capacitive coupling process for digital isolation.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other variants from the MAX22700 series such as MAX22701DASA+T or MAX22702DASA+T if additional output features are needed. Cross-family replacements like ADUM4146 or ADUM4177 may be considered but require verification of CMTI and delay matching specifications.
