30A DC Motor Driver

30A DC Motor Driver

MD30C is the successor of MD30B which is designed to drive medium to high power brushed DC motor with current capacity up to 80A peak and 30A continuously. Fully NMOS design not only provides faster switching time, it is also more efficient and no heatsink or fan is required.

Besides that, MD30C also incorporates some user friendly features such as reverse polarity protection and onboard PWM generator which allows it to operate without a host controller. The motor can simply be controlled with the onboard switches and speed potentiometer. External switches and potentiometer can also be used.
**Note that it is not for "RC PWM" 

MD30C is now Revision 2.0. 

Features:

• Bi-directional control for 1 brushed DC motor.

• Motor Voltage: 5V - 25V 30V

• Maximum Current: 80A peak (1 second), 30A continuously.

• Reverse polarity protection.

• 3.3V and 5V logic level input.

• 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 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.
