looking for a good power chip for dc motor controler
Hello
be low is a link to a pdf file to some chips i just received from ti samples area. I was wondering if someone could look at the pdf and tell me if i could us this chip to build a cd motor controller. I dont have and l293d chips at my disposal .. and TI dont give those out for samples. If i have more samples to look through if i find any that may do the trick also i will post them in this thread
thanks for the advice..

so the chip listed in the pdf is not suitable to use even if i build in a circuit that would bring the voltage down to the needed level. Mike i am really trying to understand this stuff I had a very hard and humbling lab last night in my digital and analog circuit class. I can seem to get all these equations for figuring out what this and that does. i have book here out the yin yang and i am trying very hard so please bare with me as i as stupid question and my duplicate questions. I am not a dummy for some reason it just keeps confusing me. When it clicks though it will be easy but until there. I ask humbly ask for your patience

There are some excellent articles on the Wikipedia on H-bridges. Do a Google search for "wiki h bridge". You'll find out how these work and how to build them.
This describes a simple H-bridge built from cheap parts. The author quotes a cost of $5 per H-bridge as of 5 years ago. Call or e-mail some of the manufacturers or distributors for the transistors and optoisolator. You might be able to get some samples. It never hurts to ask.
man When God made you he broke the mold you really know your stuff I have followed a lot of your post i have seen patience that i could never muster and you seem to have forgot more than i will ever seem to know at this point.
Again thanks a lot for all of your help. I hope that that patience that you have shone in the past will be shared with me. I really need help (more ways than one)LOL as i said i am really struggling in my class the other 2 vb.net and graphics and animation are easy but that electronics class has shone me how much i really dont know or understand. I will beat it but it will take time. Not having any spare money really sucks so i am trying any trick i know.
thanks again Mike

Part of what I'm trying to say is that you too can look like you know a lot. There are lots and lots of basic books on learning logic design and basic circuit design, not from a theoretically correct standpoint, but from a practical "I just need something that works" standpoint. There's a lot of really basic thinking involved ... like Ohms Law (E = I x R) and the Power Law (P = E x I) and knowing about RC time constants.
