Controller ICs for Stepper Motors

Image

Analog controllers are compact, simple and cost effective, and represent an integrated solution to sense and control the current in stepper motors. When used in conjunction with dual or single H-bridge products, the chipset forms a constant-current drive for an inductive load and performs all interface functions from control logic through to the power stage.
