EVALSTGAP2SICD

EVALSTGAP2SICD is a demonstration board for STGAP2SICD 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 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. The device allows implementing negative gate driving and the on-board isolated DC-DC converters allow working with optimized driving voltage for SiC MOSFETs. The EVALSTGAP2SICD board allows evaluating all the STGAP2SICD features while driving a half-bridge power stage with voltage rating up to 1200V in TO-220 or TO-247 package.
