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.
