TC642BEOA Description

Short technical summary and product information.

The TC642BEOA from Microchip Technology is a switch-mode fan speed controller designed for temperature-proportional control, reducing acoustic noise and extending fan life. It operates within a 3.0V to 5.5V supply range and supports any fan voltage, making it versatile for various applications.

 

This device utilizes efficient Pulse Width Modulation (PWM) for fan drive. Key features include Microchip's proprietary FanSense™ technology for fault detection, protecting against fan failure and aiding system testing. It also incorporates a fan auto-restart function and a shutdown mode for "Green" systems. The TC642B variant offers over-temperature indication.

 

The TC642BEOA is suitable for applications such as personal computers, servers, LCD projectors, and datacom equipment. It supports low-cost NTC/PTC thermistors for temperature sensing and allows for minimum fan speed setting via a resistor divider. The controller is available in a space-saving 8-pin SOIC package, designed for surface mounting.

 

With an operating temperature range of -40°C to +85°C (TA), the TC642BEOA is built for reliable performance in demanding environments. Its design facilitates general-purpose fan speed control, enhancing system cooling and longevity.
