Motor control device and control method thereof

The invention provides a motor control device and a control method thereof, the motor control device comprises a detection control circuit and a driving circuit, and the driving circuit comprises a first part pin and a second part pin; the detection control circuit is used for controlling a first part of pins and a second part of pins of the driving circuit to drive the motor in a first mode when the motor voltage meets a first voltage value or the motor current meets a first current value; and the detection control circuit is used for controlling a second part of pins of the driving circuit to drive the motor in a second mode when the motor voltage meets a second voltage value or the motor current meets a second current value. According to the application, different pins of the drive circuit are controlled through the detection control circuit to switch different modes to drive the motor and discharge the current generated by the reverse voltage of the motor, the safety is ensured, the design cost is reduced, the structure is simple, the method is simple and convenient, and the applicability is high.
