4.3.1.1 MOSFET
The Evaluation Board has MOSFETs for the motor drive. It is also possible to connect external MOSFET
board to CN_EXT_MOS (external MOSFET connector). The default setting of Evaluation Board has a 0[Ω]
resistors mounted on the MOSFET connection selection resistors (R79-R87), so the MOSFET mounted on the
Evaluation Board is enabled. In this configuration, the connection of external MOSFET board to
CN_EXT_MOS is prohibited. When connecting external MOSFET board, remove the MOSFET connection
selection resistors (R79-R87) and mount 0[Ω] resistors to the MOSFET connection selection resistors (R88-
R96). By mounting 0[Ω] resistors in the MOSFET connection selection resistors (R88-R96), the gate and
source of the MOSFET mounted on the Evaluation Board are connected to the PGND to prevent the
penetration breakdown.
Note: Depending on the motor, control method and main power supply voltage, the MOSFETs mounted on the Evaluation Board may be
damaged by exceeding the absolute maximum rating. In this case, consider replacing the MOSFETs or using an external MOSFET
board.
