The LB1867M 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 ofvariations, from LOW speed to H-High speed and from 60 cm t0 120 cm square using the same PCB. This makes it easy to design highly reliable fan motor installations.
