1. INTRODUCTION/OVERVIEW
MDD10A is the dual channel version of MD10C which is designed to drive 2 brushed DC
motors with high current up to 10A continuously. Just like MD10C, the MDD10A also
supports locked-antiphase and sign-magnitude PWM signal. It is also using full solid state
components which result in faster response time and eliminate the wear and tear of the
mechanical relay.

1. Sign-Magnitude PWM – For sign-magnitude PWM operation, 2 control signals are used to
control the speed and direction of the motor. PWM is feed to the PWM pin to control the
speed while DIR pin is used to control the direction of the motor.
2. Locked-Antiphase PWM – For locked-antiphase PWM operation, only 1 control signal is
needed to control the speed and direction of the motor. PWM pin is connected to logic high
while the DIR pin is being feed with the PWM signal. When the PWM signal has 50% duty
cycle, the motor stops running. If the PWM has less than 50% duty cycle, the motor will turn
CW (or CCW depending on the connection). If the PWM signal has more than 50% duty
cycle, motor will turn CCW (or CW depending on the connection).
