Abstract

PURPOSE:To simplify the circuit constitution by providing a pulse insulating circuit in a loop circuit from the output of the DC-motor driving circuit to the input, insulating the part between said output and input, and using a pulse signal for transmitting the signal between said output and input. CONSTITUTION:A driving circuit 10 including transistors 10-1-10-4 is connected to the DC motor 14, and the current of the motor 14 is detected by a detecting resistor 16. The detected signal is supplied to a comparator 28, and compared with a reference voltage 30. Then, the compared signal is given to the pulse insulating circuit 32, the input and the output are insulated, and the driving circuit 10 is turned on and off via a switch control circuit 34. Therefore, the signal based on the voltage detected by the resistor 16 is given to a gate circuit 36 from a pulse insulating circuit 32, drives the bases of the transistors 10-1-10-4, and a pulse signal is used for transmitting the signal between the output and input. In this constitution, the circuit can be simplified and the reliability can be enhanced.
