Hi,

We cover automotive-grade products here while the L6235Q is an industrial-grade. 

I will move your post in the Analog Community.

On the other side, the information you provide is quite limited for the colleagues to be able to troubleshoot your problem. 

If you want to see a complete 3-phase motor driving with automotive-grade products, you can refer to AEK-MOT-3P99081 or AEK-MOT-3P9908M.
