1.INTRODUCTION/OVERVIEWMDD10A 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 lockedantiphase and signmagnitude PWM signal. It is also
using full solid state components which result in faster response
time and eliminate the wear and tear of the
mechanicalrelay.MDD10Ahasbeendesignedwiththecapabilitiesandfeaturesof:
Bidirectionalcontrolfor2brushedDCmotors.
Supportmotorvoltagerangesfrom5Vto25V.
Maximumcurrentupto10Acontinuousand30Apeak(10second)foreachchannel.
Solid state components provide faster response time and eliminate
the wear and tear
ofmechanicalrelay.
FullyNMOSHBridgeforbetterefficiencyandnoheatsinkisrequired.
SpeedcontrolPWMfrequencyupto20KHz.
SupportbothlockedantiphaseandsignmagnitudePWMoperation.

6.GETTINGSTARTED
6.1GettingStartedMDD10AwithSK40CMDD10Aiscompatiblewith2typesofPWMoperation,whichare:
1. SignMagnitude PWM For signmagnitude 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
thespeedwhileDIRpinisusedtocontrolthedirectionofthemotor.
2. LockedAntiphase PWM For lockedantiphase 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
than50%dutycycle,motorwillturnCCW(orCWdependingontheconnection).
