Brushed-Motors generate Electrical-Noise, or "Hash" over a wide variety of Frequencies,
extending up to many MHz and sometimes even into the GHz region.

This "Hash" can easily destroy Semiconductors,
and must be suppressed for the safety of the Components in the Controller.

It has nothing to do with the Start-Up-Current-Spike,
which is caused by the fact that the Motor is in a "stalled", ( zero-RPM ), condition at start-up.

I have been using the IXDI630MYI, and it has been working well, except for the current consumption when it's off, which is about 0.75mA. While this isn't much, having two of them on my PCB results in a total of about 1.5mA. Since my application is battery-powered, this is something I would prefer to avoid. Is there any way to reduce this?

In the future, I am considering using something like the DRV8847PWPR, which I am currently using in another application to drive latching solenoids. As for this project my pump does not use more then 2A, I don't see why this could not also work

 

There are at least hundreds of Chips that could do the job.

You must do your own research and experimental tests.

I can not guarantee your success.

There are people in these Forums who are experienced enough to guarantee a design that they create,
but they are not likely to do it for free, because it takes a substantial amount of time and effort.

Why are You concerned with a ~1mA Quesent-Current-Draw ?
Your Battery will probably last at least several weeks before needing a charge,
and your Battery gets charged every day, = not a problem.
