Description

ALARM

PHASE

The circuits consist of an LS-TTL compatible logic

input, a current sensor, a monostable and an

output stage with built-in protection diodes. Two

TEA3718 ICs and a few external components

form a complete control and drive unit for LS-TTL

or microprocessor-controlled stepper motor

systems.
