DESCRIPTION
The TEA3718 and TEA3718S are bipolar monolithic
integrated circuits intended to control and drive the
current in one winding of a bipolar stepper motor.
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
or TEA3718S and a few external components form
a complete control and drive unit for LS-TTL or mi-
croprocessor-controlled stepper motor systems.
