Stepper Motor Controller
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.
