LB11685AV
Monolithic Digital IC
3-phase sensor less
Motor driver
Overview
The LB11685AV is a three-phase full-wave current-linear-drive motor driver IC. It adopts a sensor less control system
without the use of a Hall Effect device. For quieter operation, the LB11685AV features a current soft switching circuit and
be optimal for driving the cooling fan motors used in refrigerators, etc.
Functions
• Three-phase full-wave linear drive (Hall sensor-less method )
• Built-in three-phase output voltage control circuit
• Built-in current limiter circuit
• Built-in motor lock protection circuit
• Motor lock protection detection output
• FG output made by back EMF
• Built-in thermal shut down circuit
• Beat lock prevention circuit
