The TC642VUA from Microchip Technology is a switch mode fan speed controller for brushless DC fans. It employs pulse width modulation (PWM) to achieve temperature-proportional speed control, allowing for acoustic optimization and extended fan life. The device operates within a supply voltage range of 3.0V to 5.5V, with the fan voltage being independent of the TC642 supply voltage.
Key features include Microchip's proprietary FanSense™ technology for fault detection, protecting against fan failure and aiding system testing. It also supports low-cost NTC/PTC thermistors for temperature sensing and offers a shutdown mode for energy-efficient 'green' systems. An integrated start-up timer ensures reliable motor start-up.
The TC642VUA is available in an 8-pin MSOP package, suitable for surface mount applications. Its applications span power supplies, personal computers, file servers, telecom equipment, and general-purpose fan speed control.
This controller provides efficient PWM fan drive and over-temperature indication. Minimum fan speed is adjustable via a resistor divider on the VMIN input. A logic low applied to VMIN can initiate fan shutdown.
