Product User’s Manual – MD30C
1.0 INTRODUCTION
MD30C is the successor of MD30B which is designed to drive medium to high power DC
Brushed 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, 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.
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 heatsink 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.
MD30C is Revision 2.0 since January 2016.
