Tool/software:
Hello everybody,
I want to drive the motor driver at Full Scale Current of 1,5A, so the VREF needs to be 3,3V and TRQ_DAC = 100% (according to formula on page 20).
In section "absolute maximum ratings" is written the pin can be driven with Vmax = 5,75V, but in Datasheet in table "Pin Fuctions" on page 4 is written that you can connect a maximum of 3,3V.
I will connect the pin with a voltage divider and to have the IFS = 1,5A the voltage is slightly higher as 3,3V (about 3,5V) to reach maximum current.
So the question is, if this is acceptable?
Best regards,
Alex
