DRV8803: It cannot drive stepper motor using DRV8803PWPR

Part Number: DRV8803

I have encountered an issue with DRV8803PWPR.

I used 9V to power this IC, but I want to use it to drive a 5V stepper motor.

However, it does not drive the motor to work normally.

The following is the schematic,

The following is the input and output waveforms,

   

Pls help to analysis this issue, what are the possible reason?

BTW, whether there is a pin-to-pin IC, but it can drive 5V stepper motor?

Thanks a lot.
