Monolithic Digital IC
LB1867M
Overview
2-phase Brushless
Fan Motor Driver
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.
