Product details

What this isolated gate driver brings to the board

The ADUM4122CRIZ is a single-channel isolated gate driver from the iCoupler series, built with magnetic coupling technology. It delivers 3A peak output current (source and sink) across a 5000Vrms isolation barrier, making it a solid fit for driving IGBTs and SiC MOSFETs in motor drives, inverters, and industrial power supplies.

Package and mounting

Galvanic isolation rated 5000Vrms keeps the high-voltage and control sides electrically separate. The 150kV/µs common-mode transient immunity prevents gate-signal glitches during fast switching transitions.

3A peak output — what it can and can't drive

Peak output current is 3A for both high and low. Rise and fall times are 17ns typical.

Frequently asked questions

What is the equivalent of ADUM4122CRIZ?

The closest functional equivalents within the iCoupler family are the ADUM4120-1BRIZ and ADUM4121BRIZ. The ADUM4120-1BRIZ has slightly different timing (42ns/58ns propagation delay) and 2.3A peak output, while the ADUM4121BRIZ offers 42ns/53ns delay. Neither is a drop-in replacement — the ADUM4122CRIZ has the fastest propagation delay (40ns/48ns) and the highest peak output (3A) in this trio.
