The TC642VOA713 from Microchip Technology is a switch-mode fan speed controller for brushless DC fans. It utilizes pulse width modulation (PWM) for temperature-proportional speed control, allowing for acoustic optimization and extended fan life. The device operates within a 3.0V to 5.5V supply range, with fan voltage independent of the controller's supply voltage.
Key features include Microchip's FanSense™ technology for fault detection, protecting against fan failure and aiding system testing. It also supports a shutdown mode for energy-efficient 'green' systems and can interface with low-cost NTC/PTC thermistors for temperature sensing. An integrated start-up timer ensures reliable motor start-up.
This IC is housed in a space-saving 8-pin SOIC package, suitable for surface mount applications. Its operating temperature range is 0°C to 85°C. Applications include power supplies, personal computers, file servers, and telecom equipment, providing general-purpose fan speed control.
The TC642VOA713 is designed for efficient PWM fan drive and offers over-temperature indication. Minimum fan speed can be set using a simple resistor divider on the VMIN input.
