ADIADUM4223BRWZ
Overview
The ADUM4223BRWZ is a high-voltage, isolated dual-channel gate driver based on Analog Devices iCoupler technology. It provides 5000Vrms isolation and a peak output current of 4A, making it suitable for driving MOSFETs and IGBTs in high-side and low-side configurations. This driver eliminates the timing limitations of optocouplers by providing precise 12ns rise and fall times and low propagation delay.
Why Choose This Part
The device features high 5000Vrms isolation and a wide 4.5V to 18V supply range, allowing for robust operation in harsh industrial environments. Its 4A peak output current ensures fast switching of large capacitive loads, while the 12ns typical rise and fall times minimize switching losses. Compared to optocoupler-based solutions, the iCoupler technology offers superior timing performance and long-term reliability.
Applications
Key Specifications
Getting Started
Engineers can evaluate this part using the EVAL-ADUM4223EBZ evaluation board, which provides a pre-configured layout for testing switching performance. When designing the PCB, ensure that high-frequency bypass capacitors are placed as close as possible to the VDDA and VDDB pins to handle the 4A peak current pulses. Follow the recommended creepage and clearance guidelines for the 16-SOIC wide-body package to maintain the 5000Vrms isolation rating.
