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
