Simplify and accelerate appliance design
A motor driver that 'doesn't require software'

ON Semiconductor has announced a series of devices for driving three-phase BLDC motors via 180-degree sine waves. Designed for use in cooling fans in appliances such as refrigerators, game consoles, and computer equipment, the LV8811, LV8813, and LV8814 have voltage ranges from 3.6 to 16 V and 6 to 16 V, respectively.

These newly released, highly integrated, "software-free" motor drivers reduce software development time and simplify motor control circuit design. Furthermore, they reduce acoustic noise and vibration, enabling the development of energy-efficient motor controls. Controlled by a single Hall sensor, they reduce system costs. Motor speed is set via a PWM signal or DC voltage, and the lead angle can be easily adjusted.


The LV8811, LV8813, and LV8814 feature built-in overcurrent, overvoltage, undervoltage, overtemperature, and rotor lock protection, as well as an automatic recovery function. Soft startup and shutdown functions ensure stable operation.

“Appliance manufacturers must improve the energy efficiency of their products to meet the latest guidelines,” said Ikuya Kawasaki, general manager of ON Semiconductor’s Intelligent Power Solutions business unit. “At the same time, we are under significant pressure from our customers to make our products run smoother and quieter,” he said.

He continued, "The 180-degree drive and lead-angle adjustment capabilities of the LV8811, LV8813, and LV8814 enable engineers to meet the performance requirements they most need today. This saves design engineers development time and effort, enabling them to quickly move products into mass production."
