The TC646 is a PWM fan speed controller designed for 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 and supports various fan voltages, making it versatile for different applications. The device incorporates Microchip's FanSense,Ñ¢ technology, which includes fault detection circuits to monitor fan operation and protect against failures. It also features an auto-shutdown mode for energy efficiency and supports low-cost NTC/PTC thermistors for temperature sensing. The TC646 is available in a compact 8-pin DIP package and is suitable for use in power supplies, computers, telecom equipment, and general-purpose fan speed control applications.
