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