ELM310

Stepper Motor Controller

Description

Features

The ELM310 is an interface circuit for use

• Low power CMOS design - typically 1mA at 5V

• Wide supply range - 3.0 to 5.5 volt operation

• Two inputs control both mode and motion

• No external timing components

between high speed logic outputs and four phase

stepper motor driver circuits. By suitably debouncing

mechanical switches, the circuit could also be used

for manually controlling stepper motors as well.

• Completely static operation - will maintain a step

position indefinitely

This circuit supports two popular modes of

operation, and can be switched between the two ‘on

the fly’.

• High current drive outputs - up to 25 mA

• Both half and full stepping supported

The full-step, or single phase wave mode, as it

is sometimes called, is entered into at powerup. This

mode provides sequential single phase output

signals for driving a variety of circuits with only one

output active at any one time.

• Very high speed - up to 25000 steps per second

The other mode that the ELM310 supports is the

half-step. In this case, there are eight distinct output

patterns as opposed to the four for the full-step

mode. For each step, the pattern alternates between

a single winding being energized, and two adjacent

windings, providing eight steps in total.
