Full-Wave, BLDC
Overview
The LV8811G, LV8813G, and LV8814J are 3-phase BLDC motor drivers
which are controlled with single Hall sensor. A 180 degrees sinusoidal driving
method is adopted and the IC can control motor with low vibration and the low
noise. Lead-angle adjustment is possible by external pins. The lead-angle base
and lead-angle slope 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.
