Datasheet Summary
Ordering number : EN6204A
Monolithic Digital IC
2-phase Brushless
Fan Motor Driver http://onsemi.
Overview
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 of variations, from Low speed to H-High speed and from 60cm to 120cm square using the same PCB. This makes it easy to design highly reliable fan motor installations.
