    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
