LB11685VH: Three-Phase Brushless DC Sensor-less Motor Driver
The LB11685VH is a three-phase full-wave current-linear-drive motor driver IC. It adopts a sensor less control system without the use of a Hall Effect device. For quieter operation, the LB11685VH features a current soft switching circuit and be optimal for driving the cooling fan motors used in refrigerators, etc.
特性- Three-phase full-wave linear drive (Hall sensor-less method )
- Built-in three-phase output voltage control circuit
- Built-in current limiter circuit
- Built-in motor lock protection circuit
- Motor lock protection detection output
- FG output made by back EMF
- Built-in thermal shut down circuit
- Beat lock prevention circuit
