Motor driver evaluation platform spins brushed DC, stepper motors
November 22, 2010 // Phil Ling
Texas Instruments has 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 running up to 6 A continuous/12 A peak at 50 V.
This 'out-of-the-box' 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. Applications include medical pumps, gate openers, stage lighting, textile manufacturing tools, and industrial or consumer robotics.
A modular control architecture offers flexibility to choose the right level of processing performance for the application. In addition to the C2000 controlCARD module, more TI MCU options will be available in 2011.
DRV8412 motor driver with integrated MOSFETs provides up to three times lower Rdson than competing solutions, enabling up to 97-percent efficient operation, and delivers 6-A continuous/12-A peak current at 50 V without the need for a costly heat sink. The DRV8412 motor driver also includes advanced on-chip protection, including cycle-by-cycle over-current, over-temperature, and under-voltage protection, to greatly reduce design complexity and board space, and ensure higher system reliability.
C source code and 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.
