The Microchip Technology TC664EUNTR is a PWM mode fan speed controller utilizing FanSense technology for brushless DC fans. It offers temperature-proportional fan speed control, which reduces acoustic noise and extends fan life. The device operates from a 3V to 5.5V supply and communicates via a 2-wire SMBus-compatible interface.
Key features include efficient PWM fan drive, RPM data provision, and support for any fan voltage. It is designed to work with external thermistors or voltage output temperature sensors, with the PWM output adjusted based on the input voltage. The TC664EUNTR can also be programmed via SMBus for fan speed control without an external thermistor. If the input voltage is not connected, it starts driving the fan at a default duty cycle.
This controller is suitable for applications requiring precise fan speed management, such as personal computers, servers, LCD projectors, and datacom equipment. It provides fan fault detection by monitoring the fan's RPM and asserting a fault signal if the speed drops below a programmable threshold. The device is housed in a space-saving 10-pin MSOP package and operates over a temperature range of -40°C to +85°C.
Mounting is via surface mount technology. The package is a 10-TFSOP, 10-MSOP (0.118", 3.00mm Width).
