LB1867M Datasheet Fan Motor Driver

Manufacturer: onsemi

Overview: Ordering number : EN6204A LB1867M 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.

Key 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.
