LB11850VA: Single-Phase Full-Wave Fan Motor Pre-Driver with Speed Control Function

Description: The LB11850VA is a single-phase bipolar fan motor ...
  • The LB11850VA is a single-phase bipolar fan motor driver with speed control function that works with a speed feedback signal. A highly efficient, quiet and low power consumption motor driver circuit, with a high speed accuracy and large variable speed can be implemented by adding a small number of external components. This pre-driver is optimal for driving large scale fan motors (with large air volume and large current) such as those used in servers and consumer products.
