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. 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.

13. Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted.
Product performance may not be indicated by the Electrical Characteristics if operated under different conditions.
14. Refer to the protection circuit explanation in the function description
15. For FG output pin, it is recommended to connect pull-up resistor between the pin and power supply of the controller.
16. In case PWM frequency is 30kHz, the PWM duty cycle must be within a range between 0.6% and 100% except for 0%
