CAUTION!  Using DC Power Supply only may DAMAGE this motor driver.  Use Battery instead.




The MD25HV is a high-voltage, single-channel motor driver for brushed DC motors with a voltage range of 7V to 58V. It supports 25A of continuous current without the need for an additional heatsink, thanks to its discrete NMOS H-Bridge design. The built-in buck regulator provides 5V output to power the host controller and there are onboard test buttons and LED outputs for functional testing. The motor driver can be controlled via PWM and DIR inputs and is compatible with a wide range of host controllers such as Arduino, Raspberry Pi, or PLCs. It can also be controlled directly through a potentiometer and switch without programming. The MD25HV includes overcurrent protection, temperature protection, and current limiting features to prevent damage to the motor driver and deliver its full potential under varying conditions. Note that the power input does not have reverse voltage protection and connecting the battery in reverse polarity will immediately damage the motor driver.

Examples of using the MD25HV motor driver:

  • RC cars or boats
  • Combat robots
  • Power wheels
  • Electric vehicles
  • Industrial control systems
  • High voltage motor control applications.


  • Bidirectional control for one brushed DC motor.
  • Operating Voltage: DC 7V to 58V
  • Maximum Motor Current: 25A continuous, 60A peak
  • 5V output for the host controller (250mA max)
  • Buttons for quick testing.
  • LEDs for motor output state.
  • Dual Input Mode: PWM/DIR or Potentiometer/Switch Input.
  • PWM/DIR Inputs compatible with 1.8V, 3.3V, 5V, 12V and 24V logic (Arduino, Raspberry Pi, PLC, etc).
  • PWM frequency up to 40kHz (Output frequency is fixed at 16kHz).
  • Overcurrent protection with active current limiting.
  • Temperature protection.
  • Undervoltage shutdown.
