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)
