All STGAP3S drivers work with high-voltage rails up to 1200V in circuits such as power-factor correction (PFC), power supply units, DC/DC converters, and inverters. All STGAP3S drivers have desaturation detection with soft turn-off to ensure controlled voltage and current transitions, which protects the power switch during dangerous overload or short-circuit conditions. The 6A and 10A drivers, and the new 3A drivers for SiC MOSFETs, let designers connect an external resistor to optimize the soft turn-off speed. The drivers allow negative gate voltage that strengthens unwanted turn-on prevention, protects the device during fault turn-off, and ensures robust switching without ringing during normal turn-off transitions. The complete STGAP3S family for driving IGBTs and SiC MOSFETs, including STGAP3S3, STGAP3S6, and STGAP3SX series, is in production now.
