direction interface and external power stage
oHigh precision sensor-less motor load measurement stallGuard2™
oEnergy efficiency and coolness by automatic load dependant motor current regulation
technology coolStep™ Save up to 75% of energy!
oSee the TMC262 datasheet for more information [3]
One BLDC Motor (Qmot QBL4208-41-04-006)
oMaximum rated current 1.8A, peak current 5.4A, see motor spec/user guide for more
information on electrical and mechanical parameters [6]
One Stepper Motor (Qmot QSH4218-35-10-027)
oMaximum current 1.0A, see motor spec/user guide for more information on electrical
and mechanical parameters [5]
One portable power supply with international connectors, 24V/1A (version 1.3 and higher)
Hard top case for easy handling and safe transport (version 1.3 and higher)
The Board and the driver stages support maximum motor currents of up to 2A for stepper
driver block and up to 4A (5A with good cooling) for the BLDC driver block.
Easy plug and play solution using the freely available demo design (under BSD) for the BLDC
and stepper functionality
Hall-sensor interface for BLDC motors
ABN encoder interface for high precision position measurement
oThe encoder interface can be used with the stepper or with the BLDC motor.
Various analog signals connected to the analog blocks (Signal Conditioning Blocks, SCBs) of
the Actel SmartFusion™Device for, e.g., voltage measurement
Additional RSENSE measurement pins
All signals of the Mixed Signal Expansion Header can be accessed via additional pin headers
for test and measurement
Parallel operation of BLDC and stepper motor driver
Pin-compatible to both the Actel SmartFusion™Development Kit as well as the Actel
SmartFusion™Evaluation Kit
Each driver requires a separate DC supply voltage
oThe stepper driver block (TMC262): +VM262 = 12V to 40V
oThe BLDC driver block (TMC603A): +VM603 = 12V to 48V
oUsing jumpers, a single power supply can be used for both drivers
