Hi,
I use DRV8814 and you see my schematic. I don't want to use chopper properties of IC.
Therefore I connect Avref and Bvref pins to 3v3. A1, A0, B1, B0 pins connected to gnd.
This circuit not works.
CP1 and CP2 pin voltage nearly zero volts. VCP pin voltage around of 1.5 volts.
There are something wrong but I didn't find it. I tried different ICs but problem continue.
