When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

I have a Darlington transistor to keep cool. It is a lovely chunky TIP147 in a TO247 package, attached to a PC heatsink (£6 from ebay) to get the heat out. PC heatsinks are great as they often include ...

Andigilog, the fabless semiconductor company providing intelligent thermal management solutions, has expanded its product line with two new products. The aMC8520 is the first device in the industry to ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...

I was pondering possible interfaces between a microcontroller and a 12 or 24V 5015 blower fan. The challenge is that the MCU can only drive 3.3 or 5V, while the blower needs needs a voltage as low as ...

Here is a simple mod to allow the speed of any 12V fan to be varied. All we need to do is insert a rheostat or variable resistor in the 12V wire to the fan. The rheostat should be rated at least 3 ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...
