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 • Direct PWM drive • Three-phase full-wave driving method • Soft switching driving • Built-in lock (constraint) protection circuit • Built-in lock (constraint) detection circuit • FG output (provides one Hall effe...
