五分快三计划Ceiling and industrial fans are AC-powered applications that are typically designed using many discrete power and control components. These applications have strict requirements on application performance and behavior such as audible noise, starting when the motor is already turning the opposite direction. The PAC525X family of controllers are able to implement these applications in a very small form-factor with the motor peripheral integration of the PAC525X 600V family of controllers. The firmware IP that is provided for customers of the PAC525X also contains support for silent start-up, starting a fan that is already turning and other key system-level application features of AC-powered fans.
