DESCRIPTION

The TEA3717 is a bipolar monolithic integrated cir-

cuit intended to control and drive the current in one

winding of a bipolar stepper motor. The circuit con-

sists of an LS-TTL compatible logic input, a current

sensor, a monostable and an output stage with built-

in protection diodes. Two TEA3717 and a few exter-

nal components form a complete control and drive

unit for LS-TTL or microprocessor-controlled step-

per motor systems.
