hi to all, 

             I am doing fan control using psoc 1 , but i am encountering a problem that when i am going connect 4 wire fan to pin , the voltage level at that pin is decreasing to 3 v but before connecting it shows 5v. why this reduction of voltage. and because of this fan not able to run. how to overcome this problem.

thanks 

PRP

What wires are you conneting to what pins, supplies, in your design ?

 

Do you have a schematic of your connections, and a datasheet of the fan ?

 

Does your power supply have the current capability to supply fan ?

 

Regards, Dana.

 Hello PRP,

There is an App Note on PSoC 1- Intelligent Fan Control. It can be downloaded from the link http://www.cypress.com/?rID=62757. Since you are working on a Fan Controller application, this could be useful for you.

Regards

Anshul
