Beware .1 to .01 ohm connections in P30. They can create tank circuit which can cause stepper motor failures by creating excessive voltage spikes.

How much current do you need to sink?
I used TLE6225G low side drivers with fault protection. Why re-invent the wheel on something this boring?

I think about 1.5-2.0 Amp per channel. Infineon provides a lot of excellent solutions but it's harder to find.
