I am using DRV595 now to provide a DC ouput to drive a DC fan. I have a DC input voltage as reference. Since I saw it was differential input, I have the IN- potential to be 0V. However, I see in some places in the datasheet that it has to have 3V bias, so will my circuit work when I tie IN- to GND? If it is wrong, I hope to salvage this prototype. My circuit has 3.3V source as well. Will it be okay to tie IN- to 3.3V instead of exact 3V?
