Mouser Electronics, Inc., today announced immediate availability of newest DC motor control solutions from Texas Instruments.

The TI DRV8843 is a dual H-bridge driver capable of driving two DC motors or one stepper motor. The output block of each driver consists of n-channel power MOSFETs configured as H-bridges that are able to supply up to 2.5A peak or 1.75A RMS output current. 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.
