TI Launches Industry's First 24V Sinusoidal, Sensorless, Brushless DC Motor Driver for Silent Fan and Small Pump Applications
Published2014.11.05 13:59Minimize board space and shorten the design cycle,
A single IC solution that reduces audible noise by up to 75%
TI Korea (CEO Kent Chon, www.ti.com/ww/kr ) October 20, 2014 – TI (CEO Kent Chon) has launched the industry's first 24V, pure sine wave, sensorless, brushless DC (BLDC) motor driver. By utilizing a 3A driver with integrated control logic, the DRV10983 provides the ability to rapidly tune motors with reliable start-ups and optimized performance. Featuring 180-degree, pure sine wave, sensorless technology, the DRV10983 is up to 75% quieter than competing solutions and is suitable for applications such as cooling fans, ceiling fans, blowers, and small appliances. (For more information on the DRV10983 or to order samples, please visit www.ti.com/drv10983-pr-kr ) 
Key Features and Advantages of DRV10983
• Very quiet operation: 180-degree pure sine wave, sensorless operation combined with an advanced startup algorithm provides up to 75% quieter operation than competing solutions and does not cause pop and click during startup. Reduces noise combined with pure tone harmonics in fan applications by up to 25 dBA
• Code-Free Configuration: Various motor tuning options enabling optimized performance and reliable startup with simple register settings, without the need for complex microcontroller coding or motor knowledge.
• Complete Protection Set: Built-in advanced on-chip protection features, including overvoltage surge protection (AVS), overcurrent, overthermal, shoot-through, undervoltage lockout, and enhanced 5-stage rotor lock protection, reduce design complexity and increase system reliability.
• Fully Integrated Solution: A single-chip solution integrating power FETs, sensorless control logic, and optional 100mA, 3.3V, or 5V step-down converters, reducing board space and system costs while shortening development time.
Tools and Support
The DRV10983EVM evaluation module can drive a 3-phase BLDC motor as a cost-effective sensorless solution. The EVM, which includes a BLDC motor, provides a graphical user interface (GUI), schematics, and Gerber files, and is available for purchase at $99.
Supply timing, packaging, and price
The DRV10983 is available in a 24-pin, 8mm x 6mm HTSSOP package, with a recommended retail price starting at $1.19 for a quantity of 1,000.
