Ordering number : ENN 6202 LB1868 Monolithic Digital IC LB1868 Two-Phase Brushless Fan Motor Driver Preliminary Overview The LB1868 is a 2-phase unipolar brushless motor driver.
With only a few peripheral parts, lockup protection and automatic recovery can be implemented.
The IC can be configured for 12V or 24V operation and a wide range of variations, from LOW speed to H-High speed and from 60 cm to 120 cm square using the same PCB.
This makes it easy to design highly reliable fan motor i
