Hello. I designed a driver board with the IC DRV8432 to run a stepper motor. Can anyone please explain to me the use of the pins RESET_AB & RESET_CD?
I designed a board without using these pins. Schematic attached.
I am trying to run a bipolar stepper motor by sending PWM signal to the inputs of the driver board but I am getting only a low signal (0.6V) at the outputs. PVDD= 25V (from SMPS) ) & GVDD=12V (on board regulator 7812).
Please point out my mistakes.
Thank you.
