ELM311 Datasheet Stepper Motor Controller

Manufacturer: ELM Electronics

Overview: ELM311 Stepper Motor Controller.

Datasheet Details

The ELM311 is an interface circuit for use between high speed logic and four phase stepper motor driver circuits.

All of the logic required to provide stepping in two directions is contained in this one 8 pin package.

This circuit supports only one mode of operation, the full-step, or single phase wave mode, as it is sometimes called.

Low power CMOS design - typically 1mA at 5V.
Wide supply range - 3.0 to 5.5 volt operation.
Two inputs control Full step motion.
No external timing components.
Completely static operation - will maintain a step position indefinitely.
High current drive outputs - up to 25 mA.
Very high speed - up to 25000 steps per second Connection Diagram PDIP and SOIC (top view).
