STMicroelectronics Demonstration Board for STGAP2SM for STGAP2SM Isolated 4 A Single Gate

The gate driver is characterized by 4 A current capability and rail-to-rail outputs, making the device suitable also for high power inverter applications such as motor drivers in industrial applications equipped with MOSFET/IGBT/SiC power switch. Two different variants are available: one with separated source and sink outputs, the other with single output pin and a dedicated pin for Miller clamp function. The EVALSTGAP2S is suitable for both output configuration variants. The device integrates protection functions: UVLO and thermal shutdown are included to simplify the design of high reliability systems. Dual input pins allow choosing the control signal polarity and also implementing HW interlocking protection in order to avoid cross-conduction in case of controller malfunction. The device allows the implementation of negative gate driving, and the on-board isolated DC-DC converters allow working with optimized driving voltage for MOSFET/IGBT or SiC.
