I had to use the sleep mode to turn the voltage off from the motor. I would say the 330 mA rated is per phase. It gets very hot unless it is hooked to some kind of heat dissipation thing. I think that is what is going on the easydrive chip can take that current but it needs an aluminum on top to dissipate heat. Now, 12V/36 aprox 334 mA times 2 aprox 670 mA. times two I was able to read aprox 280 mA total from my power supply. I was able to see that always both set of coil are energized when pulses are not going in the easy drive. I was able to see how the signals change per set of coils when I send pulses from my Signal generator from low and high frequency (couple of HZ to 10Khz). I connected 2 LED back to back with 1K resistor each as one set of coils and another set of LEDs for the second set of coils. I did check the cables and I saw the pulses on my scope.
