DRV8818 Motor Output Current Specification

What is the max current per channel (AOUT+, AOUT-, BOUT+, BOUT-)? I know the device is rated for 2.5A, but as I am designing the PCB I need to know some current specifications for each of the individual lines. I am assuming each line doesn’t need to carry the full 2.5A, but I am not sure of this and wanted to check what an appropriate current would be for which to design.
Let me know so I don't end up with excessively large traces and headers.
