Cytron MDD10A DC Motor Driver Dual Channel 10Amp 5V-30VDC
The Cytron MDD10A is a dual-channel DC motor driver designed to control brushed DC motors. It is capable of handling up to 10A of continuous current per channel and a peak current of 30A for brief moments. The driver supports a motor voltage range from 5V to 30V (Rev2.0), making it suitable for a variety of robotic and motorized systems. Unlike older models, the MDD10A uses solid-state components that ensure faster response times and eliminate the wear and tear associated with mechanical relays, offering greater reliability and longevity.
The MDD10A offers flexibility in motor control through its support for both sign-magnitude and locked-antiphase PWM signal operations. These modes allow the user to control the speed and direction of the motors easily. The driver supports TTL PWM inputs from microcontrollers, making it ideal for integration into custom robotics and automation projects. It also features onboard push buttons for manual motor control, providing additional convenience for testing and setup.
The MDD10A is equipped with a variety of features for efficient operation, including full NMOS H-Bridge technology, which eliminates the need for a heat sink. It is designed to work with a battery for driving inductive loads like DC motors, as many power supplies shut down when regenerative currents are detected. The driver is compact yet powerful, making it a great choice for mobile robots, RC vehicles, and other applications that require precise motor control.
Features:
- Bi-directional control for 2 brushed DC motors.
- Support motor voltage ranges from 5V to 25V 30V (Rev2.0).
- Maximum current up to 10A continuous and 30A peak (10 seconds) for each channel.
- Solid state components provide faster response time and eliminate the wear and tear
of mechanical relay. - Fully NMOS H-Bridge for better efficiency and no heat sink is required.
- Speed control PWM frequency up to 20KHz (Actual output frequency is same as
input frequency). - Support both locked-antiphase and sign-magnitude PWM operation.
- Support TTL PWM from microcontroller, not PWM from RC receiver.
- Onboard push button to control the motor manually.
- Dimension: 84.5mm x 62mm.
Note: Please use the battery when driving inductive load such as DC brush motor. Due to
the protection circuit of most power supply (switching), it will shut down when
regenerative current from the motor is detected.

Note: Please use battery when driving inductive load such as DC brush motor. Due to the
protection circuit of most Power supply (switching), it will shut down when regenerative
current from motor is detected. Even if the case where switching power supply is needed, a
battery with the same rated voltage need to be parallel with the power supply to absorb the
regenerative current.
