TEA3717 Description
The TEA3717 is a bipolar monolithic integrated circuit intended to control and drive the current in one winding of a bipolar stepper motor. The circuit consists of an LS-TTL patible logic input, a current sensor, a monostable and an outputstage with builtin protection diodes. Two TEA3717 and a few external ponents form a plete control and drive unit for LS-TTL or microprocessor-controlled stepper motor systems.
