LB1868M Datasheet | onsemi

2‐phase Brushless Fan Motor Driver Monolithic Digital IC 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 12 V or 24 V 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.
