LV8805SV: Motor Driver, Sensor Less, Brushless, 3-Phase
LV8805SV is a 3-phase sensorless motor driver IC. 3-phase driver allows low power consumption and low vibration. And Hall sensorless drive allows reduction of the size of a motor system. This IC is suitable for use in products which require high reliability and long life such as server fan and refrigerator fan.
