EVALSTGAP2HDM

EVALSTGAP2HDM is a demonstration board for STGAP2HDM isolated 4A half-bridge gate driver. The gate driver is characterized by 4A 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 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. The device allows implementing negative gate driving and the on-board isolated DC-DC converters allow working with optimized driving voltage for MOSFET, IGBT. The EVALSTGAP2HDM board allows evaluating all the STGAP2HDM features while driving a half-bridge power stage with voltage rating up to 1200V in TO-220 or TO-247 package.
