I am using DRV8834 in one of my project. Where in I am not getting enough torque. If I increase current, keeping Vref constant, both Avref and Bvref connected directly to VREFO, and changing (decreasing) value of sense resistors, heating of coil will become an issue.
I am using in indexer mode.
Can a better torque be achieved by configuring the IC in phase/enable mode?
Also Phase/Enable mode is not clearly explained in the datasheet, can you please explain it in more detailed manner, how to use it, in a simpler language?
