650 V 60A GaN Half-Bridge and Driver with Over Current Protection

GS-EVB-HB-66516T-RN is a 650 V 60A GaN Half-Bridge and RAA226110 gate drive demonstration board. This evaluation kit consists of two GaN Systems 650V GaN E-mode transistors “GS66516T” and all necessary circuits including half bridge gate drivers, isolated power supplies and optional heatsink to form a functional half bridge power stage. It allows users to easily evaluate the GaN E-modes performance in any half bridge-based topology, either with the universal mother board (P/N: GS665MB-EVB) or users’ own system design.
