Abstract
In activating a motor, a gate voltage with which a power semiconductor element may supply a rush current of the motor is generated by a charge pump circuit, when a certain time (time until the rush current ends) has elapsed after activating the motor, a timer circuit operates a gate clamp circuit, which reduces the gate voltage of the power semiconductor element to reduce the current-carrying capability of the power semiconductor element. Subsequently, when the motor has caused a short-circuit failure, the power semiconductor element, because its gate voltage is reduced by the gate clamp circuit in advance, supplies only a load short current corresponding to the reduced gate voltage. Accordingly, the heat generation due to the short-circuit current is also small and an increase in temperature is also suppressed.
