LB1868
Monolithic Digital IC
2-phase Brushless
Fan Motor Driver
http://onsemi.com
Overview
The LB1868 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.
Features
Output protection Zener diode with variable withstand voltage
Z1, Z2 pins open: VOLM = 57V (24V specification)
Z1, Z2 pins shorted: VOLM = 32V (12V specification)
External Zener diode connected across Z1 VCC pins: support for fans with large drive current
External resistor allows configuration for 12V or 24V
Direct Hall element connection possible (built-in Hall amplifier with hysteresis supports core without auxiliary electrode)
Built-in output transistor with 1.0A output current (strengthened negative-current support for core without auxiliary
electrode)
Built-in rotation detection function: Low during rotation and High during stop
Built-in lockup protection with automatic recovery
Built-in thermal shutdown
