DRV10983 is a three-phase sensorless motor driverwith integrated power MOSFETs, which can providecontinuous drive current up to 2 A. The device isspecifically designed for cost-sensitive, low-noise/lowexternal component count applications.

The DRV10983 uses a proprietary sensorless controlscheme to provide continuous sinusoidal drive, whichsignificantly reduces the pure tone acoustics thattypically occur as a result of commutation. Theinterface to the device is designed to be simple andflexible. The motor can be controlled directly throughPWM, analog, or I2C inputs. Motor speed feedback isavailable through either the FG pin or I2C.

The DRV10983 features an integrated buck/linearregulator to efficiently step down the supply voltage toeither 5 or 3.3 V for powering both internal andexternal circuits. The device is available in either asleep mode or a standby mode version to conservepower when the motor is not running. The standbymode (3-mA) version leaves the regulator runningand the sleep mode (180-μA) version shuts it off. Usethe standby mode version in applications where theregulator is used to power an external microcontroller.

90-265VAC, 91% Efficiency, >0.94 PF Buck-PFC plus 24V, 30W Brushless DC Motor Drive Reference Design (ACTIVE) TIDA-00652

For achieving energy efficiency, ceiling fans and ventilation fans are moving from simple AC induction motors to brushless DC motors (BLDC). Operation of BLDC motors from AC supply requires AC-DC conversion with high efficiency and power factor. It also needs an inverter which is controlled efficiently for low noise operation. The reference design TIDA-00652 helps to meet these challenges of higher efficiency and power factor in a simpler way, by using a single stage power supply to convert the AC mains input into low voltage DC output. It also combines a fully integrated and well protected single chip sensor-less sinusoidal brushless motor controller for low noise operation.
