Monolithic Digital IC

LB11852FV

Overview

For Fan Motor

Single-phase Full-wave Pre-driver

with Speed Control Function

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

⇒

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 caused

by fluctuations in the supply voltage or load. The separately excited upper direct PWM method is featured as the

variable speed system.

•

Variable speed control is possible with external PWM input or analog voltage input

⇒

The speed control input signal is compatible with PWM duty ratio and analog voltages.

•

Soft start circuit incorporated

•

Minimum speed setting pin

⇒

The minimum speed can be set using an external resistor.

•

Current limiting circuit incorporated

⇒

Chopper type current limit at startup or lock.

•

Reactive current cut circuit incorporated

⇒

Reactive current before phase changeover is cut, ensuring highly silent and low power-consumption drive.

•

Automatic resetting type constraint circuit incorporated

•

FG (rotational speed detection) output
