The TC642VOA is a switch mode fan speed controller designed for brushless DC fans by Microchip Technology. It utilizes pulse width modulation (PWM) for temperature-proportional speed control, offering acoustic control and extended fan life. The device supports a supply voltage range of 3.0V to 5.5V, with the fan voltage being independent of the TC642 supply voltage, allowing it to support any fan voltage.
Key features include efficient PWM fan drive and FanSense™ fault detection circuits, which protect against fan failure and aid in system testing. It also offers a shutdown mode for energy-efficient 'green' systems and supports low-cost NTC/PTC thermistors. The TC642VOA is housed in a space-saving 8-pin MSOP package.
Applications for this fan speed controller include power supplies, personal computers, file servers, telecom equipment, UPSs, and power amplifiers. It is suitable for general-purpose fan speed control where precise temperature-based regulation is required.
The supply voltage range is 3.0V to 5.5V.
