Hi All,
I've been reading a bit and was wondering if there are good books specific to transistor applications when using TTL logic to drive motors etc. I'm a programmer, and understand digital logic (and/or gates etc) but I don't know how to select the proper transistor to digitally control a power load.
Assuming I have a low-voltage logic ciruit and higher voltage power circuit, I'm not sure what to measure to ensure I've got the right transistor to handle the jump.
Similarly, the power jump may be big enough to require a darlington set. I understand darlingtons permit driving greater power, but I don't know how to tell what the 'cutoff' is between a single transistior and the need for darlingtons.
Are there books that directly address digital-to-power transistor selection? If you've learned this from a college text, I'd be happy to know the ISBN etc.
If the only way to learn it is piecemeal via google, I can do that...but I'd prefer to add a good book to my library if one exists.
Many thanks,
Jerry
