Overview
The ADUM3221ARZ from Analog Devices Inc. is an isolated, 4 A dual-channel gate driver that leverages the company's iCoupler® technology. This device combines high-speed CMOS and monolithic transformer technology to provide superior performance characteristics compared to traditional gate drivers and pulse transformers. It offers true galvanic isolation between the input and each output, enabling voltage translation across the isolation barrier. This makes it ideal for applications requiring high-speed, isolated gate driving with robust safety and reliability features.
