LB1868M Datasheet Two-phase Brushless Fan Motor Driver

Manufacturer: SANYO (now Panasonic)

Overview: Ordering number : ENN6203 LB1868M Monolithic Digital IC LB1868M Two-Phase Brushless Fan Motor Driver Overview 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 60 cm to 120 cm square using the same PCB. This makes it easy to design highly reliable fan motor installations. Package Dimensions unit: mm 3111-MFP14S [LB1868M] 14 8 0.625 1.

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 between Z1 and 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 curren.
