Abstract
PURPOSE:To prevent the abnormal operation of a circuit operating as a normal and reverse drive circuit and a brake circuit by providing the circuit operating as both the normal and reverse drive circuit and brake circuit and allowing the motor to brake except when either one drive input is inputted. CONSTITUTION:When an input signal of H level is inputted to either of normal rotation input terminal S1 and reverse rotation input terminal S2 and an input signal of L level is inputted to the other input terminal S2 or S1, normal or reverse current flows through a motor M to normally or reversely rotate the motor. When the signal of H level is inputted simultaneously to both the terminals S1 and S2, transistors TrQ1, Q2 are conducted, TrQ3, Q4 are interrupted, thereby forming a brake circuit for shortcircuiting both terminals of the motor M. When the signal of L level is inputted to both the terminals S1, S2, the TrQ1, Q2 are interrupted, while the TrQ3, Q4 are conducted, thereby similarly forming the brake circuit.
