Three-phase sensorless motor driver with integrated MOSFETs delivers up to 2A

14-01-2015 | Texas Instruments | Power

Specifically designed for cost-sensitive, low-noise / low external component
count applications, the DRV10983 is a three-phase sensorless motor driver
with integrated power MOSFETs. The Texas Instruments (TI) device can
provide continuous drive current up to 2A.

Significantly reducing the pure tone acoustics that typically occur as a
result of commutation, the device uses a proprietary sensorless control
scheme to provide continuous sinusoidal drive.

The interface to the device is designed to be simple and flexible. The motor
can be controlled directly through PWM, analog, or I2C inputs. Motor speed
feedback is available through either the FG pin or I2C.
