General Description
The MDC150-012301 driver is designed to drive DC brushless motors at current of up to 30A (peak) and 
12V.  Using hall sensor feedback, a constant velocity mode can be selected.  The driver is protected against 
over current (cycle-by-cycle or latched), hall sensor error and under voltage.  When an error occurs, a 
fault light is turned on to notify the user.  Included on the driver is an internal potentiometer to control the 
maximum phase current allowed into the motor and an internal potentiometer to control the speed of the 
motor.  An optional external potentiometer (10K) or external voltage (1-4VDC) can be used to control the 
speed as well.  The direction of the motor can be preset by the direction control input.  Other inputs to 
the drive include a run/stop and a motor freewheel input.  When using the run/stop input, there are three 
ramp up profi les from standstill to select from.  The run/stop input overrides all other inputs into the driver. 
Fault Protection
Over current protection can be provided by means of a over current latch function by setting the ‘FLT 
LATCH’ dip switch on.  If a motor current level exceeding the current limit set by the internal or exter-
nal current limit potentiometer is produced, and over current latch is activated, shutting off the output.  
When a fault is detected, the driver turns off the motor current, the red FAULT LED alerts the user a 
fault occurred and the Fault Output (TB3 - Pin 5) goes low.  The Fault Output is disabled, logic ‘1’ out-
put, when the ‘FLT LATCH’ dip switch is in the off position and disabled.  This Fault protection alerts the 
user of the following conditions.
1.  Invalid Sensor Input Code
2.  Over Current.  The driver is equipped with cycle-by-cycle current limiting or over current    
   latch.
3.  Undervoltage Lockout activation at 9.1VDC for the input voltage and 4.5VDC for the    
    Hall Sensor voltage.

Heating Considerations
The temperature of the heat sink should never be allowed to rise above 70° C.  If necessary, mount the unit 
to an additional heat sink or air should be blown across the heat sink to maintain suitable temperatures.

Commutation Sequence
+ = Top Transistor ON, Bottom Transistor OFF, Current fl ows into this wire
- = Top Transistor OFF,  Bottom Transistor ON, Current fl ows out of this wire
Z = Top Transistor OFF, Bottom Transistor OFF,  No current into or out of this wire (High Impedance)
Motor Connection
Refer to the hookup diagram for typical driver applications.  When connecting a motor for the fi rst time, 
connect the hall sensor wires (5 of them) to the driver.  DO NOT CONNECT THE PHASES YET.  Turn 
on power and rotate the motor by hand.  If the RED FAULT LED comes on, the hall phases are incor-
rectly wired.  If the RED FAULT LED does not come on then the hall wires are connected correctly.  
Power the unit down and proceed to connect the motor phases.  If the motor does not run or runs 
erratically, power down and check the speed potentiometer and make sure the phases are connected 
correctly.  There are six different ways to connect the phase wires, and normally only two will allow the 
motor to rotate, but only one is correct.  If the direction of the motor is changed and the no-load current 
of the motor is approximately the same and the motor runs smoothly in both directions then the phase 
wires are correct.
The wiring of the motor phases should be separated from the hall and input connections to not allow a 
possible source of interference.

Motor Freewheel
The motor freewheel feature allows the de-energizing of the motor phases.  A high (open) input at this input 
causes the motor to run at the given speed, while a low at this input causes the motor to coast to a stop.
Motor Run/Stop
The motor run/stop feature allows the stopping of a motor by shorting out the bottom drives of the three 
phases.  A low at this input allows the motor to run,  while a high (open) input does not allow motor opera-
tion and if operating causes rapid deceleration.
Motor Direction
The motor direction feature allows the changing of the rotation of the motor.  This input should not be 
changed while motion is in progress.  A high (open) input causes the motor to turn in the CW direction, 
while a low at this input causes the motor to turn in the CCW direction.
Speed Adjust Setting
There are two ways to set the speed on this drive.  One is to use the on board potentiometer.  The other 
is to use an external 10K potentiometer.   To use the on board potentiometer, set jumper JP2 to position 
1-2 (default).  To use the external 10K potentiometer or external 1V to 4V voltage speed setting, remove 
cover and set jumper JP2 to position 2-3.  A voltage of 1V-4V to control the speed of the motor can be 
tied to the Pot Wiper connection of P1 with 0V tied to pin 6 of TB3 (GND). 
The mating connector for the external 10K potentiometer is Molex part number 3-640440-3.
Speed Output
The PG OUT terminal (TB3 - pin 1) is used to determine the speed of the motor shaft.  A 5V signal pulse 
out is shown at a rate of 4 pulses for 1 revolution of an 8-pole motor, 3 pulse for 1 revolution of a 6-pole 
motor, and 2 pulses for 1 revolution of a 4-pole motor.
Fault Output
The Fault Output is only active when the Fault Latch is enabled, setting the ‘FLT LATCH’ dip switch on.  
The TTL level Fault Output indicates an over current or failure in the motor/driver operation.  The Fault 
Output is normally at a TTL logic level 1.  If a fault occurs, the Fault Output will go to a TTL logic level 0.
