TC647VOA Description

Short technical summary and product information.

The TC647VOA from Microchip Technology is a switch-mode fan speed controller designed for brushless DC fans. It employs pulse width modulation (PWM) to achieve temperature-proportional speed control, contributing to acoustic management and extended fan life. The device supports a wide supply voltage range of 3.0V to 5.5V, with the fan voltage being independent of the TC647 supply, allowing compatibility with any fan voltage.

Key features include FanSense™ technology for fault detection against fan failure and system testing aid, and a shutdown mode for energy-efficient systems. It supports low-cost NTC/PTC thermistors for temperature sensing. The TC647VOA is available in space-saving 8-pin MSOP, SOIC, and PDIP packages, and operates across an industrial temperature range of -40°C to +125°C.

This controller is suitable for applications such as power supplies, personal computers, file servers, telecom equipment, UPSs, and power amplifiers, offering general-purpose fan speed control.
