E-TEA3718SFPTR

Overview

The E-TEA3718SFPTR is a bipolar stepper motor driver from STMicroelectronics, housed in a 20-SOIC surface-mount package. It operates with a supply voltage of 4.75V to 5.25V and supports load voltages between 10V and 45V. The device delivers an output current of 1.5A per channel and features two half-bridge outputs. It supports step resolutions of 1 and 1/2, includes LS-TTL compatible logic inputs, and integrates a current sensor with built-in protection diodes.

Feature Summary

Integrates full control and power stages for bipolar stepper motors
Includes internal current sensing and monostable timing functions
Features built-in protection diodes in the output stage

Applications

General purpose bipolar stepper motor control
Industrial automation systems requiring integrated drive solutions
Motion control applications with LS-TTL logic interfaces

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the 'E-' prefix aligns with your component sourcing requirements. Ensure the 20-SOIC footprint matches your PCB layout. Check RoHS compliance status if required by your manufacturing standards. Validate the operating temperature range against your environmental constraints.

Selection Notes

Select this component for applications requiring a compact surface-mount solution for bipolar stepper motors. It is suitable where LS-TTL compatibility is necessary for logic interfacing. Consider the 1.5A output capability for moderate load requirements. The integrated design reduces external component count compared to discrete solutions. Verify thermal management needs given the SOIC package constraints.

Part Context

This part belongs to the TEA3718 series of motor drivers. It serves as a specialized integrated circuit for controlling bipolar stepper motors. The series offers a complete drive solution combining logic, control, and power stages. It is designed for applications needing reliable motion control with minimal external components.
