Hall bias minus-side bias pin. Minus-side bias pin of Hall element is connected with this pin. In addition, connect a bias resistance between Hall element plus-side bias and power supply. www.DataSheet4U.com Equivalent Circuit VR 3 4 VM RF Power supply pin. Connect a capacitor between this pin .

Ordering number : ENA0665 www.DataSheet4U.com LB11681H Overview Monolithic Digital IC PWM Three-phase Brushless Motor Driver The LB11681H is a three-phase brushless fan motor driver IC. This IC uses a PWM soft switching drive-method (for low-noise drive). Since this IC includes a motor constraint protection circuit necessary for a fan motor system, highly reliable products including this IC can be designed. Also, this IC can be operated with 12V single power supply. Functions Dir.
