DESCRIPTION

The TEF3718 and TEF3718S are bipolar monolithic

integrated circuits intended to control and drive the

current in one widing of a bipolar stepper motor. The

circuits consists of an LS-TLL - compatible logic in-

put, a current sensor, a monostable and an output

stage with built-in protection diodes. Two TEF3718

or TEF3718S and a few external components form

a complete control and drive unit for LS-TTL or mi-

croprocessor controlled stepper motor systems.
