●The LV8813G-AH is a 3-phase, PWM, full wave, BLDC motor driver in 20 pin TSSOP package. This 3-phase full wave (sinusoidal) driver is controlled by single hall sensor. A 180degrees sinusoidal driving method is adopted and IC can control motor with low vibration and 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 (0.5ohm). The hall sensor bias driver is equipped and hall IC is supported as well. As a method of the rotary speed control of motor, direct PWM pulse input or DC voltage input can be chosen. The LV8813G-AH has stable start-up even with a large load and suitable for large size fans. It has built-in current limit circuit and thermal protection circuit.
