Choose a High CMTI Gate Driver That Cuts Your SiC Switch Dead-Time

By: Suravi Karmacharya and Michael Jackson

Abstract:

As GaN and SiC FETs begin to replace MOSFET and IGBT technologies in power switching applications, we discuss the key specifications to look for when selecting an isolated gate driver. We explain the importance of CMTI and propagation delay skew and present an isolated gate driver IC ideal for use with these new power transistors.
