ELM313

Stepper Motor Controller

Description

Features

The ELM313 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 (two phase) motion

• No external timing components

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.

• Completely static operation - will maintain a step

position indefinitely

This circuit supports only the full-step two phase

mode of operation. This mode provides sequential

phase control output signals for driving a variety of

motors. In this mode, two phases are always

energized, providing several advantages over single

phase full (wave) stepping, at the cost of higher

power consumption by the motor.

• High current drive outputs - up to 25 mA

• Very high speed - up to 25000 steps per second

The ELM313 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.
