I am using a stepper motor DRV8835. I have put in the function as the IN/IN mode (MODE =0), For AIN1, AIN2, BIN1 and BIN2 we gave signal as 0101 and the output voltage I was expecting as 0V, 5V, 0V, 5V. But the output voltage showed up as 5V, 0V, 2V, 2V. Does anyone know how to fix this problem?
We are using DRV8835DSSR stepper motor driver
With MODE 0 IN/IN mode we have tested the driver with several AIN1, AIN2, BIN1, BIN2 inputs
with 1010 input, the voltages are 5V, 0V, 0V,0V
with 0101 input, the voltages are 5V, 0V, 2V, 2V
Could you let me know where is problem?

In reply to Rick Duncan:
Yes we are using a custom PCB. There is no short. Measured voltage using DMM. We will assemble another board.
Also could you let me know if DRV 8835 is the best board for stepper motor control? Our motor is 3-5V. We need very low sleep current.Current rating is ~1A. Small number of pins is better.
I ordered another PCB to try. Could you let me know what is the series of codes we need to send to Ain1:Ain2:Bin1:Bin2 to run a 4-wire stepper motor?
