Overview
The ADuM3220ARZ-RL7, produced by Analog Devices Inc., is an isolated, 4 A dual-channel gate driver based on the iCoupler® technology. This component combines high-speed CMOS and monolithic transformer technology to provide superior performance characteristics compared to traditional gate drivers. It offers true galvanic isolation between the input and each output, enabling voltage translation across the isolation barrier. The ADuM3220 is particularly useful in applications requiring high-speed, isolated gate driving with robust protection features such as shoot-through protection and thermal shutdown.
