Sine-Wave 3-Phase Brushless DC Motor Driver IC: TB6585FTG

The TB6585FTG in a small surface-mount package (7 mm × 7 mm) is functionally equivalent to the TB6585 three-phase, full-wave brushless DC (BLDC) motor driver. Sine-wave drive results in quiet motor operation. Additionally, lead angle and PWM control provide high efficiency.
