Sensorless 150° series
Product Overview
With the fast development of technology in these years, BLDC has been widely applied in the products with strict requirements on acoustic noise, reliability, efficiency and so on. For responding Chinese government's call on energy-saving and environmental protection, Fortior has developed a series of ICs for BLDC driver. Fortior launched sensor 150° series to meet application needs of low cost and low noise. This series of product adopts 150° quasi-sine control method and supports closed-loop speed control.
Product Application
This series of product is widely used in all kinds of pumps and fans.
