LB11683H

Monolithic Digital IC

Three-Phase Sensorless Motor Driver

http://onsemi.com

Overview

The LB11683H is a three-phase full-wave current-linear-drive motor driver IC. It adopts a sensorless control system

without the use of a Hall effect device. For quieter operation, the LB11683H features a current soft switching circuit

and is optimal for driving the cooling fan motors used in refrigerators, etc.

Functions

• Current linear drive

• Built-in current limiter circuit

• Output stage oversaturation prevention circuit

• Coil counter-electromotive FG output

• Built-in thermal shutdown circuit

• Beat lock prevention circuit

• Lock protection circuit

• Lock detection output
