ON Semiconductor LV885x Brushless DC Motor Controllers

ON Semiconductor LV885x Brushless DC Motor Controllers are pre-drivers for single-phase PWM BLDC motors with closed-loop controller for motor rotation speed. These motor controllers control motors with low vibration and low noise. The LV885x motor controllers feature various built-in circuits for current limit, thermal protection, locked rotor protection, and auto recovery. These motor controllers offer independent adjustment options for lead-angle value and lead angle slant. The LV885x motor controllers come with a lineup of different closed-loop gain selection and rotation signal output selection. Typical applications include PC, computing equipment, refrigerator, and games.
