HA13568AT
Key Features
- 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
- Holds the level used for IC internal processing fixed even if the B-EMF level fluctuates due to the rotation speed
- This circuit generates a voltage about 1.5 V above that of the VSPN pin
- Booster pumping capacitor connection 3 HA13568AT Pin Description (cont) Pin No
