I designed a motor driver with the new Texas Instruments DRV8262 at its core. It will be used in robots controlled by an ESP32.

It works well when using non-PWM signals to switch the outputs in PWM mode, but as soon as I use a PWM signal it won't work anymore. I tried different frequencies from 50 Hz all the way to 150 kHz, but nothing worked. The only thing I could notice was the current draw of the whole system increasing from ~210 mA to ~230 mA. The driver didn't get warm at all and the nFault pin was at 3.3 V, which is the default state. The schematic isn't my finest work, but I hope it works.
What can I do to make the driver respond to PWM signals?

Datasheet: DRV8262 I hope I provided all the information needed.

    \$\begingroup\$ It looks like you have MODE2 grounded- I think that changes the function of IN from PWM to PH/EN. Double check the datasheet. \$\endgroup\$ Commented Apr 5, 2024 at 21:06
  • \$\begingroup\$ @JohnD sorry, should've clarified. I put 0-Ohm resistors there for me to be able to change modes. I first tried PH/EN mode, which didn't work with PWM and then removed the resistor for it to go into PWM mode. \$\endgroup\$ Commented Apr 6, 2024 at 8:04

  • \$\begingroup\$ Where does the VCC supply come from? A capacitor is missing at VCC. What do you mean with "nothing worked"? \$\endgroup\$ Commented Apr 7, 2024 at 16:43
