    摘要: The motor driver having a plurality of output circuits each having two switching elements connected in series includes: a phase switch circuit for putting a switching element on one side of one output circuit among the plurality of output circuits in the ON state during a time period corresponding to a predetermined electrical angle, and performing switching operation for switching elements on the other side of plural output circuits among the remaining output circuits; and a conduction period control section. The conduction period control section generates a signal for controlling the switching operation. Specifically, when the number of times of switching operation performed during the time period corresponding to the predetermined electrical angle is equal to or less than a predetermined value, a switching element corresponding to a phase, for which the magnitude of the current should be decreased, is turned OFF in the time period corresponding to the next predetermined electrical angle.

    摘要: The present invention inexpensively controls a turn-on and turn-off switching speed for MOS transistors made in accordance with various specifications. According to the present invention, during an output voltage rise period for a turn-on operation of the MOS transistor, a fixed current determined by a first clip circuit and a resistor is input to a gate terminal of the MOS transistor to obtain a linear rise slew rate. During an output voltage drop period for a turn-off operation of the MOS transistor, a fixed current determined by a second clip circuit 38 and a resistor is input to the gate terminal of the MOS transistor to obtain a linear drop slew rate.
