Texas Instruments introduced the first in a new line of scalable evaluation platforms for spinning motors.
The DRV8412 evaluation kit (DRV8412-C2-KIT) includes all of the hardware and software needed to spin two brushed DC motors or a single stepper motor out of the box. The kit speeds development time for brushed DC and stepper motors running up to 6 A continuous/12 A peak at 50 V. Applications include medical pumps, gate openers, stage lighting, textile manufacturing tools, and industrial or consumer robotics.
The motor control and driver solution includes the DRV8412 motor driver, a real-time control C2000 Piccolo microcontroller (MCU) controlCARD module, a quickstart GUI, full development source code, Code Composer Studio (CCStudio) integrated development environment (IDE) and motors. Its modular control architecture offers flexibility to choose the right level of processing performance for the application.
The DRV8412 motor driver with integrated MOSFETs provides very low Rdson, enabling up to 97% efficient operation, and delivers 6 A continuous/12 A peak current at 50 V without the need for a heatsink. It also includes advanced on-chip protection, including cycle-by-cycle over-current, over-temperature and under-voltage protection.
The C2000 Piccolo MCU performs control, communications and debug. It integrates advanced control peripherals as well as access to a thorough set of motor control software modules, real-time debug capabilities, and open-tooled reference designs via free controlSUITE software.
C source code and an easy-to-use GUI demonstrate voltage and current control of one or two brushed DC motors, as well as speed and index, including up to 128 microsteps, of a stepper motor.
