The GD3100 is a programmable high-voltage gate driver with advanced functional safety (FuSa), control, and protection features, developed for automotive and eMobility applications. This presentation will give a brief review of HV power devices such as Si IGBTs and WBG MOSFETs. Then the talk will focus on key features of the GD3100 that are important for implementation of high traction inverters, DC/DC converters, or on-board chargers (OBCs) using Si IGBTs or SiC MOSFETs.
