Ordering number : ENA0674 LB11683V

Monolithic Digital IC

Three-Phase Sensorless Motor Driver

Overview

The LB11683V 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 LB11683V 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
