Applications
The TEA3718 is a bipolar monolithic integrated
circuit intended to control and drive the current in
one winding of a bipolar stepper motor.
Description
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.
