Can anyone recommend a surface mount package of a nice little H bridge IC to use with a 5volt UNO to driver a little dc motor. Ive used the SN754410 in the past, and am hoping to find something comparable to that. My motor only draws 300 ma, so something that works up to 1.0 amp would be plenty. I've searched digi key, but there are so many and so many different options that I'm not sure about...
I looked at the TB6612FNG, which Sparkfun sells a breakout of, it its awfully small pads. I see a chip that's called soic20 package, which looks a little better for a first time smd solderer!
I found this!

...theres so many different elements that could make a chip not the right chip, but as far as I can tell this should work?
I have one 12volt motor
Driving it with a 5 volt Uc like the UNO or pro mini.
The motor draws about 300 mA.
Do I understand this chip correctly, that it's basically just like a L293, only it'll just run one motor? So I wire it up the same way, using 2 control pins off my UNO to control the main power to the motor through this IC? --I'll have forward and reverse, right?
If so, this will take up a lot less space, when that's a priority.
Thanks.

More or less, yes - it should work fine; it seems to have a few minor/fundamental differences to the L293 (such as MOSFET drivers instead of BJT), but in general its just another h-bridge driver IC.
