Allegro MicroSystems A89301 Ultra Low Noise FOC Motor Controller

Allegro MicroSystems A89301 Ultra Low Noise FOC Motor Controller is a three-phase, sensorless, brushless DC (BLDC) motor driver that operates from 5.5V to 50V. This controller features a field-oriented control (FOC) algorithm that is fully integrated to achieve the highest efficiency and acoustic noise performance. The A89301 optimizes the motor startup performance in a stationary condition, a windmill condition, and even in a reverse windmill condition. Motor speed is controlled through PWM, analog, or CLOCK input, while closed-loop speed control is optional, and the RPM-to-clock frequency ratio is programmable. Allegro MicroSystems A89301 Ultra Low Noise FOC Motor Controller is available in a 24-contact 4mm x 4mm QFN package with an exposed thermal pad.
