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.
