Product Overview
Product Description
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.
Features
 
  • Pre-driver for single-phase full-wave drive
  • On-chip speed control circuit
  • External PWM input or analog voltage input enabling variable speed control
  • On-chip soft start circuit
  • Reactive current cut circuit incorporated
  • Constraint protection and automatic reset functions incorporated
  • FG (speed detection), RD (lock detection) output
  • Constant-voltage output pin for hall bias
