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.
* MDD10A being shipping after Jan 2017 are Rev2.0 which have upgraded to support
maximum motor voltage up to 30V.
