Connect a filter C to this pin during GND. V phase low pass filter. Connect a filter C to this pin during GND. U phase low pass filter. Connect a filter C to this pin during GND. Reference voltage of spindle and slide Spindle control input. Generates forward torque when a DC voltage higher than REFIN is applied, and brake when a DC voltage lower than REF is applied. For AGC. Holds the level used for IC internal processing fixed even if the B-EMF level fluctuates due to the rotation speed.
