Designed for use in cooling fans of household appliances such as refrigerators, as well as games consoles and computing equipment, the LV8811, LV8813, and LV8814 have voltage ranges of 3.6 volts (V) to 16 V, 6 to 16 V, and 3.6 to 16 V respectively. As well as giving software-free designs, they reduce acoustic noise and vibration, and enable deployment of energy efficient motor controls. They can be controlled by a single Hall sensor, reducing system costs. Motor speed can be set by either a pulse width modulated (PWM) signal or a DC voltage and lead angle can easily be adjusted.
The parts have full protection including locked rotor protection and auto-recovery mechanisms. Soft start-up and shutdown functionality ensures that ongoing operational stability is maintained.
In TSSOP-20J/SSOP-20 packages, they are respectively priced at $0.938 (LV8811/LV8813) and $0.785 (LV8814) (all 2000).
