3.2 Specifications

Wide bandgap SiC-based power modules become popular in power electronics because of their excellent conduction and switching performance. Compact driver board UCC2189X5YQEVM-096 supports SiC modules by reducing parasitics, minimizing switching loss, and providing full required protection and diagnostics features. For the full elctrical specifications table, refer to the UCC2189X5Y-Q1 datasheet
