  • Page 2: High Voltage Safety Precautions

    [8] Be sure to wear insulated gloves when handling is required during operation. After Use [9] The ROHM Evaluation Board contains circuits which store high voltage. Since it stores charges even after turning off the connected power circuits, please discharge the electricity after using it, and please deal with it after confirming such electric discharge.

    6.１.1 Peripheral circuits for gate resistors and soft turn-off resistors The SiC-MOSFET is driven by ROHM’s gate driver IC BM60054AFV-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 6.１.２...
