Four half-bridge switchers for about $5. Current and thermal limiting.
I was about to dremel and test my own half-bridge driver, but won't
now. I guess I'll have to shuffle up the abstraction stack.
 
There must be something cool that these could be used for. A
16-channel power supply?

It's a lot smaller than the four 1/2 bridges I was considering. Each
had an SO8 driver chip, two dpak fets, and a bunch of discretes.

I was about to Dremel this:

That chip will need cooling somehow. I'll run the eval board and see
how hot it gets.
