Overview
The E-TEA3718SDP is a bipolar monolithic integrated circuit designed by STMicroelectronics to control and drive the current in one winding of a bipolar stepper motor. This IC is part of the TEA3718 family and is specifically packaged in a Power DIP 16 format. It integrates an LS-TTL compatible logic input, a current sensor, a monostable, and an output stage with built-in protection diodes. Two E-TEA3718SDP ICs, along with a few external components, can form a complete control and drive unit for LS-TTL or microprocessor-controlled stepper motor systems.
