Hi Igor,
What is the charge pump voltage (VCP with respect to GND) when trying to drive the outputs?
What is the V3P3OUT voltage?
With no motor connected and the following inputs:
IN1 = Logic low
IN2 = Logic High
nSLEEP = Logic High
nRESET = Logic High
I4 = Logic High
I3 through I0 = X
VREF =
OUT1 should be 0V and OUT2 should be VM. If not, there could a problem with the device or the board.
