Motor control device

The invention provides for a motor control device that includes a drive circuit (200) to drive an H-bridge circuit (100) to control a current fed to a motor (110), a drive command signal generator (300) to generate a drive command signal including a pulse signal having predetermined drive frequency and duty for sending a command to drive the motor (110), a current detection circuit (400) operable to output a comparison output signal on comparison between a current detection signal of a motor current and a target value signal, a latch circuit (500) arranged to hold a current detection result based on an ON signal of the drive command and the comparison output signal, a gate circuit (600) ranged to drive the drive circuit (200) based on the ON signal of the drive command and a latch output signal from the latch circuit (500), and a control unit (800) arranged to change the duty of the drive command signal based on the current detection result.
