The DRV8843 is available in a thermally enhanced 28-pin HTSSOP package and is ideal for applications such as robotics, factory automation, and office machines.
The combination of Texas Instruments and National has created an exciting, flexible solution for the control of brushless DC motors. This “winning combo” provides programmable processing to support varying drive profiles and configurations with differences in range, acceleration, and torque. Both single- and three-phase motors can be controlled, as well as applications with and without sensors. Four components comprise the solution: the LM5101B MOSFET driver, the LM3S8971 Stellaris motor controller, the AMC1200 isolation amplifier, and the DRV8312 motor driver.
Design of a new motor control system can be a daunting task. Using many of the same products found in their winning combo solution, TI has created the DK-LM3S-DRV8312 Motor Control Kit to help engineers speed time to market. The kit is designed to spin 3-phase brushless DC motors showing the operational advantages of TI’s InstaSPIN BLDC control solution such as simplified tuning, immediate acceleration, and reliable low-speed operation. The brains of the kit are an LM3S818 MCU on a controlCARD module that is pre-programmed with all the necessary firmware. Also included is the Crosshairs embedded kernel and corresponding PC application interface that enables the engineer to control and monitor the entire system.
