The utility model discloses a motor drive circuit and a motor. The circuit comprises an integrated circuit, a filter circuit used for filtering a power supply VIN, a diode D1 used for preventing current from flowing back to the power supply VIN, a connecting end P2, a connecting end P4 and a connecting end P5. The power supply VIN is connected to the integrated circuit through the filter circuit, the integrated circuit generates driving signals which are respectively connected to the connecting end P2, the connecting end P4 and the connecting end P5, and the connecting end P2, the connecting end P4 and the connecting end P5 serve as output ends of the driving circuit. The driving circuit provided by the utility model is formed by the integrated circuit, and the integrated circuit forms the driving signal for driving the motor, so that the use of discrete components is reduced, the circuit structure is simplified, the circuit volume is reduced, the difficulty of PCB (Printed Circuit Board) layout and wiring is
