Ordering number : ENN6203 LB1868M Monolithic Digital IC LB1868M Two-Phase Brushless Fan Motor Driver Overview The LB1868M 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 installations. .
