Fan 4 Click Board

The Fan 4 Click Board™ is a very compact, two-wire fan driver. It utilizes an integrated 5V, DC, brushless-motor driver chip. Its output voltage regulation and current limiting capabilities allow the speed control for the two-wire DC brushless motors. The Click Board™ uses the LTC1695 IC, which features an integrated 6-bit DAC. The DAC regulates the output voltage in the range from 0 to 4.92V. This IC also has some additional features, such as the maximum output current limiting, and thermal shutdown protection. There is also a startup boost timer which ensures reliable startup of the fan, connected to the output terminal.
