48V Telecom fans are a growing market for BLDC motors. This application typically has a high-density of fans in a small area on a single PCB. Because this application is always running, factors such as efficiency and audible noise are key design considerations.
The PAC family of controllers support for this type of application by offering products that integrate high-performance motor control peripherals in the IC as well as a rich firmware IP platform that can meet the complex application processing requirements of these appliances. IP such as FOC allows customers to realize higher-efficiency controllers that can run with less audible noise than the typical trapezoidal control BLDC applications.
