ELM311

Stepper Motor Controller

Description

Features

The ELM311 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 Full step motion

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.

• No external timing components

• Completely static operation - will maintain a step

position indefinitely

This circuit supports only one mode of operation,

the full-step, or single phase wave mode, as it is

sometimes called. This mode provides sequential

single phase output signals for driving a variety of

motors. For dual mode operation, the ELM310

should be considered.

• High current drive outputs - up to 25 mA

• Very high speed - up to 25000 steps per second

The ELM311 can be controlled by a wide variety

of circuits, due to its fully static operation. In addition

to using high speed microprocessor control, suitably

debounced mechanical switches or continuously

running oscillator circuits could also be used.
