    6.１.1 Peripheral circuits for gate resistors and soft turn-off resistors The SiC-MOSFET is driven by ROHM’s gate driver IC BM6112FV-C. When the SCP function is activated, the MOSFET will be turned-off slowly (soft turn-off). The turn off time is based on soft turn-off resistors. The schematics are shown in Figure 11 and Figure 14 6.１.２...
