Brushed DC Motor Control Module features CAN interface.

Press Release Summary:



Model MDL-BDC24, Black Jaguar Stellaris® Brushed DC Motor Control Module with CAN provides variable speed control for 12 and 24 V brushed DC motors at up to 40 A continuous current. It has RS232-based serial control input that also functions as serial-to-CAN bridge, as well as 32-bit Stellaris® MCU to implement open-loop voltage control and closed-loop control of speed, position, or motor current. Analog components such as CAN transceiver, DC/DC converter, and voltage regulator are included.



Original Press Release:



Texas Instruments Unveils the "Next-Generation" Stellaris® Brushed DC Motor Control Module with CAN (MDL-BDC24)



The MDL-BDC24 "Black Jaguar" offers a direct replacement for Texas Instruments' MDL-BDC, the official CAN-enabled speed controller of the FIRST Robotics Competition (FRC) Kit of Parts

The Stellaris® Brushed DC Motor Control Module with CAN (MDL-BDC24) improves on the highly successful MDL-BDC design by providing variable speed control for both 12 V and 24 V brushed DC motors at up to 40 A continuous current, while adding a new RS232-based serial control input that also functions as a serial-to-CAN bridge. The MDL-BDC24 includes a rich set of sensor interfaces, connectivity, and control options, including analog and quadrature encoder interfaces, high performance Controller Area Network (CAN) interfaces, and an RS232 port. The module features highly optimized software and a powerful 32-bit Stellaris® microcontroller to implement open-loop voltage control as well as closed-loop control of speed, position, or motor current. The H-bridge on the MDL-BDC24 is run at high frequency through the MCU's integrated PWM interface and enables DC motors to run smoothly and quietly over a broad speed range.

The MDL-BDC24 is powered by the ARM® Cortex(TM)-M3-based Stellaris LM3S2616 microcontroller that provides efficient and deterministic performance while integrating CAN, UART, and advanced motion control capabilities. The MDL-BDC24 design also incorporates high-quality analog components from Texas Instruments, including the SN65HVD1050 CAN Transceiver, MAX3221 RS232 Line Driver/Receiver, TPS54040 Swift DC/DC Converter, TPS73633 Voltage Regulator, and INA193 Current Shunt Monitor. The MDL-BDC24 is suitable for a wide variety of consumer and industrial applications, including factory automation devices and systems, mobile robots, household appliances, pumping and ventilation systems, and electric wheelchairs and mobility devices.
