Abstract

PURPOSE:To prevent the power source from short circuit due to an erronous signal by a method wherein two pairs of switching means forming the power source supplying circuit and an earthing circuit of motors for the normal revolution and inversion use are installed and when a motor is in standstill, multi pairs of power supplying circuit are placed in noncontinuity. CONSTITUTION:When a zero potential is applied to a terminal FIN and a high potential is applied to RIN, by means of operation of switches 2, 3 motor driving transistors 43, 42, 38 are turned ON and a motor 1 turns normally. And further, when a high potential is applied to the terminal FIN and a zero potential is applied to RIN, then, motor driving transistors 41, 40, 37 are turned ON to turn the motor 1 reversely. When a low potential or a high potential is applied to both the terminal FIN and RIN, then at least, transistors 40-43 forming the power soruce circuit of the motor 1 are turned OFF to stop the motor 1.
