MAX22700EASA+T

Isolators - Gate Drivers Overview

The MAX22700EASA+T is a single-channel, ultra-high common-mode transient immunity (CMTI) gate driver designed for silicon carbide (SiC) and gallium nitride (GaN) power devices. It utilizes capacitive coupling technology to provide robust isolation with a rated voltage of 3000Vrms. The device operates within an input supply range of 13V to 36V and supports output currents of 2.35A (high) and 3.7A (low). Key electrical parameters include a maximum propagation delay of 36ns, typical rise/fall times of 3.6ns/1.8ns, and a minimum CMTI of 300kV/µs. It functions across a temperature range of -40°C to +125°C in an 8-SOIC package.

Isolators - Gate Drivers Feature Summary

• Ultra-high common-mode transient immunity of 300kV/µs minimizes false triggering in high-noise environments

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when sourcing. Confirm that the component meets required insulation coordination standards for your application's safety certification. Check current availability status as supply constraints may affect lead times. Ensure the 8-SOIC footprint matches your PCB layout design rules before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching of wide-bandgap devices requires exceptional noise immunity. The 3000Vrms isolation rating suits applications with significant potential differences between control and power domains. Consider the 36ns propagation delay for timing-critical synchronous rectification or bridge leg control schemes where signal integrity is paramount.
