I just have a few quick questions about Allegro's A3977 chip
1) Is it true that you should not use a socket with these, due to their method of using the ground pads as heat sinks? If so, would it be beneficial to have a large copper pad underneath the chip on the board, and use some thermal paste, or would it just be a waste of time?
2) I know it says the limit of this chip is 2.5A, but would it be able to handle 2.8A with heat sinks and lots of airflow?
Thanks,
