  • The LV8811G is a 3-phase BLDC motor driver which is controlled by single Hall sensor. A 180 degrees sinusoidal driving method is adopted and the IC can control motor with low vibration and the low noise. In addition, lead-angle adjustment is possible by an external pin. Lead-angle value and lead-angle slant can be adjusted independently. Thus, the device can be driven by high efficiency and low noise with various motors. The power element to drive a motor is built-in and contributes to high efficiency by low on resistance (0.5 Ω). The Hall sensor bias driver is equipped, and a Hall IC is supported as well. As a method of the rotary speed control of the motor, direct-PWM pulse input or DC-voltage input can be chosen.
  • Features
  • 3-phase full wave (sinusoidal) drive - Static sound, low vibration, high efficiency
  • Any practical combination of slot and pole can be handled. (e.g. 3S3P, 3S4P, 6S4P, 6S8P, 12S8P, 9S12P and so on) - Versatility
  • built-in power FETs (P-MOS/N-MOS) - Part mark reduction. The implementation area small
  • Speed control function by direct PWM or DC voltage input - Speed control is possible by two methods.(selectable)
  • Minimum input PWM duty cycle can be configured by voltage input - It is contributed to movement stability
  • Soft start-up function and soft shutdown function - It is contributed to static sound characteristics at the time of the start
  • Soft PWM duty cycle transitions - Static sound characteristics at the time of the speed abnormality are good
  • Built-in current limit circuit and thermal protection circuit - Safe use is provided by a protection function
  • Regulated voltage output pin for Hall sensor bias - A PCB design is easy
  • Built-in locked rotor protection and auto recovery circuit - Safe use is provided by a protection function
  • FG signal output - A measurement of the number of revolutions is possible
  • Dynamic lead angle adjustment with respect to rotational speed - High efficiency
  • Lead-angle control parameters can be configured by voltage inputs - High efficiency
