TC649VOA Description

Short technical summary and product information.

The Microchip Technology TC649VOA is a switch mode fan speed controller for brushless DC fans. It utilizes pulse width modulation (PWM) for temperature-proportional speed control, enabling acoustic management 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 TC649 supply voltage.

 

Key features include FanSense™ fault detection circuits to protect against fan failure and aid system testing, as well as an automatic shutdown mode for energy-efficient 'green' systems. It supports low-cost NTC/PTC thermistors for temperature sensing. The TC649VOA is housed in a space-saving 8-pin SOIC package, suitable for surface mounting.

 

This controller is designed for applications such as power supplies, computers, file servers, portable computers, telecom equipment, UPSs, and power amplifiers, providing general-purpose fan speed control. The operating temperature range is 0°C to 85°C (TA).
