LV8811G: Motor Driver, 3-Phase, PWM, Full-Wave, BLDC

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
  • Any practical combination of slot and pole can be handled. (e.g. 3S3P, 3S4P, 6S4P, 6S8P, 12S8P, 9S12P and so on)
  • built-in power FETs (P-MOS/N-MOS)
  • Speed control function by direct PWM or DC voltage input
  • Minimum input PWM duty cycle can be configured by voltage input
  • Soft start-up function and soft shutdown function
  • Soft PWM duty cycle transitions
  • Built-in current limit circuit and thermal protection circuit
  • Regulated voltage output pin for Hall sensor bias
  • Built-in locked rotor protection and auto recovery circuit
  • FG signal output
  • Dynamic lead angle adjustment with respect to rotational speed
  • Lead-angle control parameters can be configured by voltage inputs
Benefits
