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)
