Texas Instruments has debuted a dual sensorless brushless DC motor reference design capable of 130 W of total continuous output. The TIDA-00447 unit allows engineers to control two motors simultaneously while measuring just 94 mm by 65 mm.
Why it matters
This design offers a modular approach by demonstrating both discrete and integrated control architectures for low-power motor systems. It simplifies development by combining different power stages into a single, compact control unit.
The system features a 100-W stage with 4.5 A continuous current and a 30-W stage rated at 1.5 A. Both motor stages support speeds up to 2400 rpm within an ambient temperature range of -10°C to 55°C.
The players
Texas Instruments
Texas Instruments is a global semiconductor design and manufacturing company that develops analog chips and embedded processors.
The details
The 100-W stage uses an MSP430 microcontroller and external MOSFETs to perform 120-degree trapezoidal control, while the 30-W stage employs a DRV10983 driver IC for 180-degree sinusoidal control. The system utilizes a 24-V DC supply and includes an isolated UART interface for communication.
Timeline
The reference design information was published on October 1, 2026.
Roadmap
The TIDA-00447 reference design marks a shift toward highly integrated motor control, replacing bulkier, multi-board configurations with compact, sensorless solutions. This move positions the manufacturer to better serve the growing demand for efficient, small-scale industrial automation.
Engineers and product developers can use this reference to streamline the design of devices like water circulation pumps and drain pumps. It reduces the time required to implement efficient, sensorless motor control by providing a pre-tested, compact layout.
The takeaway
This reference design highlights the efficiency gains of integrating sensorless control into smaller footprints for standard 24-V applications. Developers should focus on the specific control method—trapezoidal or sinusoidal—that best fits their motor's performance requirements.
