Overview

The LB11861MC is a single-phase bipolar drive motor driver that easily implements direct PWM motor drive systems with excellent efficiency. The LB11861MC is optimal for fan motor drive in personal computer power supply systems and CPU cooling fan systems.

  • PC Power Supply system
  • CPU Cooling Fan System

  • Server
  • PC

  • Single-phase full-wave drive (16V, 1.2A transistors are built in)
  • External PWM control pin incorporated (f=16k to 50kHz)
    External PWM signal DUTY control to enable speed control to stop, medium speed, and full speed
    Slow-Decay regeneration to enable low power consumption and high-efficiency rotation control
  • Soft switching circuit incorporated
    Soft-SW circuit achieving small loss, low noise, and low vibration at a time of phase shift
  • Built-in regenerative diode (Di); only requires a minimal number of external components.
  • Built-in lock protection and automatic recovery circuits
  • FG (speed detection) outputs incorporated
  • Built-in thermal shutdown circuit.
