roduct(s) DESCRIPTION

P The TEA3717 is a bipolar monolithic integrated cir-

te cuit intended to control and drive the current in one

le winding of a bipolar stepper motor. The circuit con-

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

so sensor, a monostable and an output stage with built-

b in protection diodes. Two TEA3717 and a few exter-

O nal components form a complete control and drive

- unit for LS-TTL or microprocessor-controlled step-

) per motor systems.
