Monolithic Digital IC

Half-pre Motor Driver

Single-Phase Full-Wave,

for Fan Motor

Overview

The LB11660FV is a single-phase bipolar drive half-predriver motor driver

that can easily implement a direct PWM driver motor driver circuit with

excellent efficiency. The LB11660FV is particularly well suited for the

miniature fans used in servers.

Features

 Single-phase full-wave drive (15V, 1.5A transistors are built in)

Half predriver with integrated high side transistor

 Built-in variable speed function controlled by an external input

The LB11660FV can implement quiet, low-vibration variable speed control

using externally clocked high side transistor direct PWM drive.

 Minimum speed setting pin

 Current limiter circuit

(The limit value is determined by Rf; IO = 1A when RF = 0.5)

 Built-in kickback absorption circuit

 Soft switching circuit makes low current consumption, low loss, and low

noise drive possible at phase switching

 Built-in HB

 Built-in lock protection and automatic recovery circuits

(built-in on/off ratio switching circuit controlled by the supply voltage)

 FG (speed detection) output

 Built-in thermal protection circuit (design guarantee)
