Comprehensive Analysis of ADUM4224WCRWZ-RL

ADUM4224WCRWZ-RL is a wide-body SOIC-16 package-based isolated dual-channel gate driver, suitable for driving high-side and low-side switching devices (such as MOSFETs or IGBTs). It utilizes Analog Devices' patented iCoupler® technology to achieve an electrical isolation of up to 5000 V RMS between digital signals and power rails. This not only ensures safety but also significantly enhances the anti-interference capability.
