STGAP2SiCD Galvanically Isolated Dual Gate Driver STMicroelectronics STGAP2SiCD Galvanically Isolated 4A Dual Gate Driver is designed for galvanic isolation between each gate driving channel and the low voltage control and interface circuitry. The STGAP2SiCD gate driver is defined by 4A current capability and rail-to-rail outputs, ideal for mid and high power applications such as power conversion and industrial motor drivers inverters.
