Demonstration board for STGAP2DM isolated half-bridge gate

The STGAP2DM is an isolated half-bridge gate drivercharacterized by 4 A current capability and rail-to-rail outputs, making the device suitable also for high power applications such as motor drivers in industrial applications equipped with MOSFET, IGBT or SiC power switches.

The device integrates protection functions: dedicated SD and BRAKE pins are available, UVLO and thermal shutdown are included to easily design high reliability systems, and the interlocking function prevents outputs from being high at the same time. It enables youto implement negative gate driving, and the onboard isolated DC-DC converters allow working with optimized driving voltage for MOSFET, IGBT or SiC.

The EVALSTGAP2DM board allows to evaluate all the STGAP2DM features while driving a half-bridge power stage with voltage rating up to 1700 V in a TO-220 or TO-247 package. It alsoallows to easily select and modify the values of relevant external components in order to ease driver performance evaluation under different applicative conditions and fine pre-tuning of final application components.
