Hi,
I am using DRV8847PWPR to drive bipolar stepper motor in independent bridge interface mode.
The following is the configuration used:
Mode pin is unconnected and Sleep pin is logic high.
All inputs IN1-4 are in logic high state during power on.
Voltage measured on Mode pin is 1.23V.
All logic levels of inputs are 3.3V
VM is connected to 12V.
During the motor driving, the following pattern is observed:
OUT1 waveform is inversed of IN1
OUT2 waveform is inversed of IN2
OUT3 wavform is same as IN3
OUT4 waveform is same as IN4.
Looks like it is not in independent bridge mode.Could you please suggest me on this issue.
