Overview
The ADuM3223BRZ, produced by Analog Devices Inc., is a 4 A isolated precision half-bridge gate driver. This component utilizes Analog Devices' iCoupler technology to provide independent and isolated channels, ensuring true galvanic isolation between the input and each output. The ADuM3223 is available in a narrow-body, 16-lead SOIC package and offers high-speed CMOS and monolithic transformer technology, making it superior to alternatives such as pulse transformers and gate drivers. It operates with an input supply ranging from 3.0 V to 5.5 V, making it compatible with lower voltage systems.
