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.

Features:

－ 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
