DC Brushless Motor Drivers for Cooling Fans

Fan motors are being increasingly used in high performance, high speed electronic devices such as PCs, gaming consoles and AV/office equipment. ROHM's DC brushless fan motor drivers meet the stringent demands of even the most sophisticated products by featuring the latest technologies, including MOS output drives for large airflow and soft switching functionality in order to reduce electromagnetic noise, while multiple built-in protection circuits ensure the utmost in reliability.
