Overview
The ADUM7223BCCZ-RL7 is an isolated, half-bridge gate driver produced by Analog Devices Inc. This component utilizes Analog Devices' iCoupler® technology to provide independent and isolated high-side and low-side outputs. It combines high-speed CMOS and monolithic transformer technology, offering superior performance characteristics compared to alternatives such as pulse transformers and non-isolated gate drivers. The ADUM7223BCCZ-RL7 ensures reliable control over the switching characteristics of IGBT/MOSFET configurations across a wide range of positive or negative switching voltages, thanks to its true galvanic isolation between the input and each output.
