For reasons too complicated to explain, I am trying to drive a small brushed DC motor from the A channel of a Tic T500 board. I get very erratic output from the MP6500 driver which I’m pretty sure is due to brush noise. I can sort of fix the problem at very low currents by adding an inductive filter to the motor leads, but if I try using standard capacitive filtering (cap across motor leads, caps to motor body), the driver won’t drive at all. I’ve done this in the past with other stepper drivers (ST, Allegro), so I’m assuming the MP6500 is particularly fussy.
Does anyone know if it is possible to drive a DC motor using the DRV8834 or DRV8825 drivers on the Tic T834 and Tic T825 boards?
