Produktu pārskats
The LV8811G-AH is a 3-phase, PWM, full wave, BLDC motor driver in 20 pin TSSOP package. This is controlled by single hall sensor, a 180° sinusoidal driving method is adopted, 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, 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 a hall IC is supported as well. As a method of rotary speed control of motor, direct-PWM pulse input or DC-voltage input can be chosen. It is contributed to static sound characteristics at the time of start, safe use is provided by a protection function and a measurement of number of revolutions is possible. It is used in fan motor units, refrigerator and PC.
