The ADu M3123 provides 3000 V rms isolation in the narrow-body, 8-lead SOIC package. bining high speed CMOS and monolithic transformer technology, these isolation ponents provide outstanding performance characteristics superior to alternatives such as the bination of pulse transformers and gate drivers. The ADu M3123 operates with an input supply ranging from 3.0 V to 5.5 V, providing patibility with lower voltage systems. In parison to gate drivers employing high voltage level translation methodologies, the ADu M3123 offers the benefit of true, galvanic isolation between the input and the output. The output can continuously operate up to 380 V rms relative to the input. As a result, the ADu M3123 provides reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive and negative switching voltages.
