TC647BEOA Description

Short technical summary and product information.

The Microchip Technology TC647BEOA is a switch-mode fan speed controller that utilizes pulse width modulation (PWM) for temperature-proportional speed control. This design contributes to acoustic noise reduction and extends fan life. It supports a supply voltage range of 3.0V to 5.5V and is housed in a space-saving 8-SOIC package.

 

Key features include Microchip's proprietary FanSense™ technology for fault detection, protecting against fan failure and aiding system testing. The device also incorporates an auto-restart function for reliable motor start-up after power-on, shutdown, or transient faults. An integrated start-up timer ensures proper motor operation. The TC647BEOA is suitable for applications requiring efficient fan speed management, such as in personal computers, servers, and datacom equipment.

 

This controller operates over a temperature range of -40°C to 85°C. The fan voltage is independent of the controller's supply voltage, allowing support for any fan voltage. The device features a shutdown mode for power-saving 'green' systems and supports low-cost NTC/PTC thermistors for temperature sensing.
