PROBLEM TO BE SOLVED: To provide a motor drive device with a drive circuit for driving a motor and a protection diode where an occupation area is reduced and assembly man-hours is reduced. SOLUTION: An IC chip 10 of a drive circuit for driving a motor and a diode chip 20 of a protection diode for preventing a drive circuit from being damaged when a power supply is connected reverse are die-bonded to a first island I1 of a lead frame 30 and a second island I2, respectively, and a power supply pad P1 of the IC chip 10 is wire-bonded to the second island I2 that becomes the cathode electrode of the diode chip 20. |
