LB1868 Description
EN6202A LB1868 Monolithic Digital IC 2-phase Brushless Fan Motor Driver http://onsemi. Overview The LB1868 is a 2-phase unipolar brushless motor driver. With only a few peripheral parts, lockup protection and automatic recovery can be implemented.
LB1868 Key Features
- Output protection Zener diode with variable withstand voltage
- 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 electro
- Built-in output transistor with 1.0A output current (strengthened negative-current support for core without auxiliary
- Built-in rotation detection function: Low during rotation and High during stop
- Built-in lockup protection with automatic recovery
- Built-in thermal shutdown
