Overview
The E-TEA3718SFPTR is a bipolar monolithic integrated circuit designed by STMicroelectronics to control and drive the current in one winding of a bipolar stepper motor. This component is part of the TEA3718 series and is specifically tailored for use in LS-TTL or microprocessor-controlled stepper motor systems. The circuit includes an LS-TTL compatible logic input, a current sensor, a monostable, and an output stage with built-in protection diodes. Two TEA3718 ICs, along with a few external components, can form a complete control and drive unit for stepper motor applications.
