Abstract

PURPOSE: To expedite the response, by detecting the size of the current value by means of a comparator.
CONSTITUTION: When the current of a DC motor 2 becomes more than a specified value, the output of a current detection circuit 3 becomes H level, and a capacitor is charged through a charging integration circuit section 5. When the potential of the capacitor becomes higher than the value of the reference voltage Vref, the output of a comparator 7 becomes L level and a switching circuit 9 is turned OFF, stopping the power supply to the DC motor 2. When no current is supplied, the output of the current detection circuit 3 becomes L level and the capacitor is thereby discharged through a discharging integration circuit section 6. In starting the DC motor 2, a starting current trap circuit 11 is activated.
