SCALE™-2 and SCALE-2+ Gate Driver Cores

Power Integrations’ SCALE-2 IGBT and MOSFET gate drivers use an ASIC chip set specifically designed to reduce count, save space, and increase product reliability and functionality. A recent technology development, SCALE-2+, enables soft shut down (SSD) to be implemented in the event of a short circuit without requiring additional components (SSD function exclusive in 2SC0106T and 2SC0108T). This is particularly beneficial in applications with low stray inductance where advanced active clamping (AAC) may not be required.

Power Integrations’ gate driver cores incorporate driver functions, including galvanic isolation, protection functions, DC/DC converter etc. on board, presenting designers with a complete yet extremely flexible system solution. IGBT driver cores are available with blocking voltage capabilities from 600 V to 6,500 V and output power from 1 W to 20 W per channel. They are also suitable for driving wide bandgap devices based on emerging materials such as gallium nitride (GaN) and silicon carbide (SiC) at frequencies up to 500 kHz. Gate driver cores are supported by reference designs for fast design-ins.
