The TC664EUNTR from Microchip Technology is a PWM mode fan speed controller featuring FanSense technology for use with brushless DC fans. This device provides temperature-proportional fan speed control, which helps reduce acoustic noise and extend fan life. The voltage at the VIN pin, typically from an external thermistor or temperature sensor, dictates the PWM output, adjusted between 30% and 100%. The PWM duty cycle can also be programmed via the 2-wire SMBus-compatible interface.
Key features include efficient PWM fan drive, RPM data provision for monitoring fan operation, and software-controlled shutdown mode for energy-efficient systems. The TC664/TC665 devices support low-cost NTC/PTC thermistors and are housed in a space-saving 10-pin MSOP package. The operating temperature range is -40°C to +85°C. The TC665 variant also includes over-temperature detection.
Applications for the TC664EUNTR include personal computers, servers, LCD projectors, datacom and telecom equipment, fan trays, file servers, workstations, and general-purpose fan speed control.
