By avoiding the use of LEDs and photodiodes, this i Coupler gate drive device is able to provide precision timing characteristics not possible with optocouplers. Furthermore, the reliability and performance stability problems associated with optocoupler LEDs are avoided. In parison to gate drivers that use high voltage level translation methodologies, the ADu M1234 offers the benefit of true galvanic isolation between the input and each output. Each output can be operated up to ±700 V peak relative to the input, thereby supporting low-side switching to negative voltages. The differential voltage between the high side and low side can be as high as 700 V peak. As a result, the ADu M1234 provides reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.
