The ADuM3224/ADuM4224 are 4 A isolated, half-bridge gate drivers that employ the Analog Devices, Inc., iCoupler® technology to provide independent and isolated high-side and low-side outputs. The ADuM3224 provides 3000 V rms isolation in the narrow-body, 16-lead SOIC package, and theADuM4224 provides 5000 V rms isolation in the wide-body,16-lead SOIC package. Combining high speed CMOS andmonolithic transformer technology, these isolation componentsprovide outstanding performance characteristics superior to thealternatives, such as the combination of pulse transformers andgate drivers.
The ADuM3224/ADuM4224 isolators each provide twoindependent isolated channels. They operate with an inputsupply ranging from 3.0 V to 5.5 V, providing compatibilitywith lower voltage systems. In comparison to gate driversemploying high voltage level translation methodologies, theADuM3224/ADuM4224 offer the benefit of true, galvanicisolation between the input and each output. Each output canbe continuously operated up to 537 V peak relative to the input,thereby supporting low-side switching to negative voltages. Thedifferential voltage between the high-side and low-side can beas high as 800 V peak.
As a result, the ADuM3224/ADuM4224 provide reliablecontrol over the switching characteristics of IGBT/MOSFETconfigurations over a wide range of positive or negativeswitching voltages.
