LB11660FV

Monolithic Digital IC

Single-Phase Full-Wave

Fan Motor Driver

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 = 0.5Ω)

• 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)
