 Two-Phase Brushless Fan Motor Driver

制造商:ON

中文数据手册

产品信息

The LB1868M 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.
  • 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
  • ST pin for motor stop/drive (for standby mode of copiers etc.)
  • BC pin for kickback noise reduction (with 2 external capacitors)
  • FG output pin for rotation detection
  • Built-in thermal shutdown
