ELM312

Stepper Motor Controller

Description

The ELM312 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 the half-step mode of

operation. This mode provides eight distinct phase

control output signals for driving a variety of motors.

For dual mode operation, the ELM310 should be

considered.

The ELM312 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.

Features

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

• Wide supply range - 3.0 to 5.5 volt operation

• Two inputs control Half 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
