ST - 422M 2-phase stepper motor driver features
1. Using bipolar constant current chopper technology;
2. The structure of the modular design is much more simplified, thecost is lower;
3.8 file segmentation, eight current optional;
4. Adapter 42, 57 series stepper motor;
5. The built-in thermal over-current protection circuit.
