The new evaluation board requires only a +24 V power input and is optimised to drive SiC devices at a high speed with desaturation protection.
It is a base design that can be simplified depending upon the individual system requirements.
According to Microsemi, additional key features of the MSCSICMDD/REF1 include: adjustable -5 V to +20V output gate drive and galvanic isolation of more than 2000 V on both gate drivers.
The device is capable of 6W of gate drive power per side; 8 W with modification and offers a peak output current of up to 30A and maximum switching frequency greater than 400 KHz.
It also features single-ended or RS485/RS422 differential input gate control, shoot through (short-circuit) protection and +/- 100 kV/µS capability.
