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...
