SCALE™ Series FAQs
Q: What is the difference between SCALE-2 and SCALE-iFlex?
A: SCALE-2 drivers are plug-in solutions with fixed characteristics optimized for specific power modules, while SCALE-iFlex is a flexible, configurable platform that can be adapted to various power modules through configuration files.
Q: Can SCALE drivers be used with SiC MOSFETs?
A: Yes, several SCALE drivers are specifically optimized for SiC MOSFETs, with appropriate gate drive voltages and fast switching characteristics that take advantage of SiC technology.
Q: What is DESAT protection?
A: DESAT (Desaturation) protection is a feature that detects short-circuit or overcurrent conditions in IGBTs by monitoring the voltage across the IGBT when it should be conducting. If a fault is detected, the driver immediately turns off the IGBT safely.
