Industry's first 24-V, sinusoidal, sensorless, brushless DC motor driver quiets noise in fan and small pump applications

DALLAS, TX -- Texas Instruments introducesthe industry's first 24-V, sinusoidal, sensorless, brushless DC (BLDC) motor driver. The DRV10983 gives customers the ability to quickly tune their motors for reliable start-up and optimal performance using a configurable, 3-A driver with integrated control logic. Utilizing 180-degree, sinusoidal, sensorless technology, the DRV10983 is up to 75 percent quieter than competing solutions for applications like cooling fans, ceiling fans, blowers and small appliances.

Key features and benefits of the DRV10983:

•Ultra-quiet operation: 180-degree pure sinusoidal, sensorless operation, coupled with advanced start-up algorithms, enables up to 75 percent quieter operation than the competition, with no annoying clicks or pops at start-up. Pure tone harmonics, a significant noise adder in fan applications, are reduced by as much as 25 dBA.
•Code-free configurability: Tune a wide range of motors for optimal performance and reliable start-up through simple register settings without the need for complex microcontroller coding or motor knowledge.
•Full suite of protection: Advanced on-chip protection, including anti-voltage surge (AVS) over-voltage, over-current, over-temperature, shoot-through, under-voltage lock-out and advanced five-stage rotor lock protection, reduces design complexity and increases system reliability.
•Fully integrated solution: Single-chip solution with integrated power FETs, sensorless control logic and optional 100-mA, 3.3- or 5-V step-down converter reduce board space, system cost and development time

Tools and Support

The DRV10983EVM evaluation module (EVM) is a cost effective, sensorless solution for running three-phase BLDC motors. The EVM includes a BLDC motor and comes complete with a graphical user interface (GUI), schematics and Gerber files for US$99.

Availability, packaging and pricing
The DRV10983 is available in a 24-pin, 8-mm x 6-mm HTSSOP package. Suggested retail pricing in 1,000-unit quantities starts at US$1.19.
