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)
