Part of our Tech Chat series

Commode Mode Transient Immunity as it relates to gate drivers is explained in this Tech Chat as well as the minimum gate driver CMTI required for converters integrated with Gallium Nitride (GaN) or Silicon Carbide (SiC) power semiconductors. CM Transients can affect gate driver timing and performance. Incorrect gate signals cause converter misbehavior and/or failure. Selecting the right gate driver with sufficiently high CMTI means better performance for GaN or SiC converters.
