Overview
The ADuM3220WARZ-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, including true galvanic isolation between the input and each output. This isolation enables voltage translation across the isolation barrier, making it ideal for applications requiring high reliability and safety. The ADuM3220WARZ-RL7 operates with input supply voltages ranging from 3.0 V to 5.5 V and output supply voltages from 4.5 V to 18 V, depending on the variant (A or B).
