This is MD30C DC brushed motor driver. It is the successor of MD30B which is designed to drive medium to high power brushed DC motor with output current up to 80A peak (1 second) and 30A continuously. Full NMOS(solid state) design not only provides faster switching time, it is also more efficient and no heatsink or fan is required to get 30A continuous at room temperature.

Besides that, MD30C also incorporates some user friendly features such as reverse polarity protection for Vin/Vmotor and onboard PWM generator which allows it to operate without additional controller. The motor can simply be controlled with the onboard switches and potentiometer. External switches and potentiometer can also be used.


Which motor is good to be driven by MD30C? As long as the motor:
  • DC Brushed motor (Two terminals)
  • Operating voltage from 5V to 30VDC
  • Rated Current <= 30A
  • Peak Current <= 80A

Example of suitable DC brush motor with MD10C (Not limit to):

  • Relatively low current motor: SPG50 series, SPG30 and SPG30E series, IG45 series, IG42 series, IG32 series, DKM 40W series.
  • Power Window Motor with coupling, left or right, or Wheel kit
  • 350W Electric Scooter Motor
  • 450W Electric Scooter Motor with Gear
  • DKM 120W series
  • Bi-directional control for 1 brushed DC motor, single channel
  • Motor Voltage: 5V to 30VDC
  • Maximum Output Current: 80A peak (1 second), 30A continuous
  • Reverse polarity protection for Vmotor
  • 3.3V and 5V logic level input
  • Full NMOS H-Bridge for higher efficiency and no heat sink is required
  • Regenerative Braking
  • Brakes the motor when PWM pin is low (logic low)
  • Speed control PWM frequency up to 20KHz (Actual output frequency is same as input frequency when external PWM is selected)
  • Onboard PWM generator with switches and potentiometer for standalone operation
  • Support both locked-antiphase and sign-magnitude for external PWM operation. Note: PWM is not “RC PWM”
Dimension: ~94mm x ~79mm
