Isolated Gate Drivers Infineon Isolated Gate Drivers use magnetically-coupled coreless transformer (CT) technology to provide signal transfer across galvanic isolation. These drivers offer functional basic, reinforced isolated, UL 1577, and VDE 0884 certified products. The isolation allows for very large voltage swings (e.g. ±1200V). These isolated drivers incorporate the most important key features and parameters for MOSFET, IGBT, IGBT modules, SiC MOSFET, and GaN HEMT driving.
