Hello Team!
I made a wrong connection to the DRV8842 IC and blew it up, so I wanted to replace it manually. I Dissoldered the broken chip with a hot air soldering tool, which was complicated because of the powerpad, but I manged to do it. I connected a new chip in the position and it is not doing well. I get a strange 100Hz output, even with both input pins on GND. Do you have any idea what can cause this 100Hz signal? Is this a well-known error?
Thank you very much!
Igor
