L6470 & Maximum currect limiting

Hi,

I'm evaluating the L6470 for a project.
Going over the datasheet I noticed that the minimum value for 'maximum current limiting' is 375mA.

I need to drive a very small stepper (6mm) with 12V power source. According to the manufacture, the current should be limited to 100mA.
Most stepper drivers have a simple sense resistor for limiting the current, unfortunately the L6470 doesn't.

I can get a 5V variation of the motor that can handle a higher current (410mA) but the driver is designed for 8V (minimum)

Is there a way to solve this issue, limit the current to 100mA in some way so I could use the L6470 in my project?

Thanks

Gilad.
