This is a little belated - I've been kind of busy & have gotten behind
on email - but I want to extend my thanks to Russell, Gerhard, and Olin
for their explanation of the high side/low side terminology. 

I have to thank Gerhard for including links to the data sheets, partly
because it's good to have a diagram to illustrate the usage of the
concepts that Russell described, but also because he turned me onto a
couple of devices that I had no idea existed. The IPS5451 datasheet sent
me off on a search that uncovered a device which is ideal for my
application. (http://www.st.com/stonline/books/pdf/docs/7370.pdf) These
are only $2.28 each from Mouser. I have a couple of PWM applications in
mind, for which the VN820 is an excellent match. I doubt I would have
found that item if I hadn't asked my question here.
