Just want to know if anyone has worked with this IC. http://www.maxim-ic.com/appnotes.cfm/appnote_number/941/ln/en It seems pretty awesome to me, but my electronic skills are well.. not nearly enough to make a circuit for this. I'd be curious to see your thoughts/ideas on this.
Hi I used the TC648 chip that offers the same functions, It uses a simpler circuit diagram, so is easier to build. The problem was selecting a resistor setting that offered the temperature range I wanted The problem is that most temp controllers like to run at full speed at quite a high temperature, I wanted one to be at full speed about 35° to keep the case cool, And off at room temperature. 20° I have some details here but I never got round to updating the page with results... Try google Kev
Thanks, and welcome to the Forums. I did try google for that IC name and all I got was the site selling the chip I guess.
sorry updated the links to the files listed at the bottom of the page. Thanks for the welcome, been reading for a while now thought it was about time I registered. Kev
Oddly enough, Maxim ran a feature on this family of chips recently in their engineering journal (volume 49) - they didn't cover the MAX6656, but they did look at some similar chips. This is a pretty funky chip, but if all you're wanting to do is monitor temperature in various places (i.e. you're not using the on-die thermal diodes, and you don't need hardware shutdown), then you might find the Dallas temperature sensor chips handy. One of the more commonly-used ones is the DS1820 . Some of the fun features include: - One-wire interface, so doesn't need oodles of interface lines - Each device has a unique address, which means you can chain a whole bundle of them together on a single data line - They come in a plastic TO-92 package, which is small enough to get most places, and can be filed down if it needs to get anywhere else - Doesn't need its own power supply - it can parasite off the data line Obviously, you would need a little electronic fun to use these directly from, say, a parallel port, but nothing complicated. Interfacing to a micro (I've done this with the Atmel AVRs) is simplicity itself. While we're on the subject of Maxim offerings (and no, I don't work for them!), there are also some funky chips for controlling fans. Check out the list National also do (or did) a range of temperature-related ICs, if you don't like Maxim or Dallas
Welcome to the forums Pandalet. I'm trying to see if I can spark anyone's interest to get some and use them, providing us (bit-tech community) with pictures and their experiences using the diodes.
