Hello all,

this is my first time in this forum and my english is not so well, so i hope for understanding.
I have a DC motor from some drill that work on 18V. I want to driving this motor with atmel 89c5131, I use L293D but it get warm up too much and the motor doesn't work, I think that the reason is too much current to push.
I need help with this, what i need to do for the motor will work.

May be you should work out the current drawn by the motor first, then you'll be more certain about what driver is suitable for the job. Have you check
L298? It's a high voltage and current device with 2 H-bridge. Read the specs, I think it can take up to 2A.
