Product Summary

The A4984SLPT is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and eighth-step modes. Step modes are selectable by MSx logic inputs. It has an output drive capacity of up to 35 V and ±2 A. The A4984SLPT includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes.
