The A89333 is a 3-phase, sensorless and brushless DC (BLDC) motor controller. A field-oriented control (FOC) algorithm is fully integrated to achieve the best efficiency and acoustic noise performance. The device also optimizes the motor startup performance in stationary condition, as well as forward and reverse windmill condition.
