The TC642CPA is a PWM fan speed controller designed for use with brushless DC fans, featuring temperature proportional speed control to enhance acoustic performance and extend fan life. It operates within a supply voltage range of 3.0V to 5.5V, allowing compatibility with various fan voltages. The device incorporates FanSense,Ñ¢ technology, which includes fault detection circuits to monitor fan operation and protect against failures. It also supports low-cost NTC/PTC thermistors for temperature sensing and includes a shutdown mode for energy-efficient applications. The TC642CPA is packaged in an 8-pin MSOP format and is suitable for a range of applications, including power supplies, personal computers, file servers, telecom equipment, and general-purpose fan speed control. It features an integrated start-up timer for reliable motor activation and provides over-temperature indication. The device is available in commercial, extended commercial, and industrial temperature ranges, making it versatile for various environmental conditions.
