Product Overview
Product Description
The LB11852FV is a single-phase bipolar driving motor pre-driver with a speed control function based on speed feedback. With a small number of external parts, a highly efficient and very quiet variable-speed drive fan motor with low power consumption and high rotational accuracy can be implemented. The LB11852FV, integrated in a miniature package, is best suited for driving small fan motors requiring speed control.
Features
 
  • Single-phase full-wave driving pre-driver
  • Speed control circuit incorporated
  • Variable speed control is possible with external PWM input or analog voltage input
  • Soft start circuit incorporated
  • Minimum speed setting pin
  • Current limiting circuit incorporated
  • Reactive current cut circuit incorporated
  • Automatic resetting type constraint circuit incorporated
  • FG (rotational speed detection) output
Applications
  • Small Fan Motor Drive
