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. 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.
