Hi,

 

Like it is given in the circuit diagram I excpect a ADC value about 2048 with no load (1,65V Offset).

Now I've connected a resistor between Phase A and C Pins. 

 

The PWM_Three_Phase_Output Signals are configured like this:

 

If I switch on the PWM I obtain a negative current in Phase C (ADC value < 2048), but I think it has to be positive.

Is there an error in the documentaion, so it has to be inverted ?

1,65V  (ADC value:4095) @ -8A

-1,65V (ADC value:0) @ 8A
