| May 15, 2023 at 9:35 | comment | added | Zhi | @SteKulov I changed it, but it is still the same. I think there might be some kind of compatibility issue when using PSpice models in LTspice. I simulated the same circuit with a more suitable op-amp in TINA-TI spice, and it shows expected behavior. | |

Do you get any behavior change if you change A1 to a buf, run the comparator output into it, and then run both outputs of the buf into the DRV8837?

Did you set Vhigh for component A1?
