DES CRI P TI O N
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 outputstage 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.
