LB11852RV Datasheet Single-phase Full-wave Pre-driver

Manufacturer: onsemi

Overview: Ordering number : ENA2133 LB11852RV Monolithic Digital IC For Fan Motor Single-phase Full-wave Pre-driver with Speed Control Function http://onsemi.com Overview The LB11852RV 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 LB11852RV, integrated in a miniature package, is best suited for driving small fan motors requiring speed control.

Key Features

  • Single-phase full-wave driving pre-driver ⇒ With a PMOS-NMOS device used as the external power transistor, low saturation output and a single-phase full-wave drive enable a high-efficiency drive with low power consumption.
  • Speed control circuit incorporated ⇒ Compared with open-loop control, a closed-loop control function that uses speed feedback to control the speed makes it possible to improve the rotational speed accuracy and reduce the variations in the rotational speed c.
