摘要
The brushless motor control device according to the present invention includes a drive controller, current detection circuits, AD converter circuits, a clock generation circuit, a pulse output circuit, and an RC filter. The drive controller generates a driving signal for driving a brushless motor. The current detection circuits each detect a current of the brushless motor. The AD converter circuits are each connected to a different one of the current detection circuits. The clock generation circuit outputs a clock pulse. The pulse output circuit outputs a pulse signal according to the clock pulse. The RC filter receives the pulse signal. The RC filter is formed of a resistor and a capacitor connected in series. A pull-up resistor connecting to a predetermined power supply is connected to an intermediate connection point between the resistor and the capacitor. The intermediate connection point is connected to the AD converter circuits. Based on output values form the AD converter circuits, it is determined whether the clock generation circuit, the AD converter circuits, and the current detection circuit are in an abnormal condition.
