摘要： A motor-driving-circuit comprising: a first to-fourth-transistors; a drive-control-circuit to control a energization-state of a motor coil so as to be a driving-state where either one group of groups of the first-and-fourth-transistors and the second-and-third-transistors is on and the other group is off, or so as to be a regeneration-state where the first-and-third-transistors are off and the second-and-fourth-transistors are on; a set-current-detection-circuit; an overcurrent-detection-circuit; and an overcurrent-protection-circuit to output a regeneration-instruction-signal for shifting the energization-state to the regeneration-state if an overcurrent-state does not occur and output a drive-stop-signal for stopping driving the coil if the overcurrent-state occurs, when a current amount flowing through the coil has reached a set-level in the driving-state, the drive-control-circuit shifting the energization-state to the regeneration-state to be maintained for a predetermined time period and thereafter returning the energization-state to the driving-state when the regeneration-instruction-signal is output, and turning off the first-to-fourth-transistors when the drive-stop-signal is output.
