LV8811G Overview
LV8811G, LV8813G Advance Information Motor Driver, 3-Phase, PWM, Full-Wave, BLDC Overview The LV8811G / LV8813G 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.
LV8811G Key Features
