Overview
The ADUM3223WCRZ from Analog Devices Inc. is a 4 A isolated, half-bridge gate driver that utilizes the company's iCoupler® technology to provide independent and isolated high-side and low-side outputs. This component is designed to offer high-speed, galvanic isolation between the input and each output, making it suitable for applications requiring precise control and high reliability.
The ADUM3223WCRZ is packaged in a narrow-body, 16-lead SOIC and provides 3000 V rms isolation. It operates with an input supply ranging from 3.0 V to 5.5 V, ensuring compatibility with lower voltage systems. The device is particularly useful in environments where high common-mode transient immunity and enhanced system-level ESD performance are critical.
