TEA3718SFP

Overview

The TEA3718SFP is a bipolar stepper motor driver manufactured by STMicroelectronics, housed in a 20-SOIC surface-mount package. It operates with a logic supply voltage of 4.75V to 5.25V and supports motor loads between 10V and 45V. The device delivers an output current of 1.5A and functions within a junction temperature range of 0°C to 150°C. Designed for LS-TTL or microprocessor-controlled systems, it integrates control and power stages.

Feature Summary

Supports full-step and half-step operation modes for precise positioning
Includes built-in protection diodes and thermal overload safeguards
Features LS-TTL compatible logic inputs for direct interfacing

Applications

LS-TTL controlled stepper motor systems
Microprocessor-driven motion control units
Bipolar stepper motor drive applications

Procurement Notes

Verify the exact suffix against official documentation, as variations like E-TEA3718SDP indicate obsolete status while others remain active. Confirm package type and RoHS compliance before integration. Cross-reference datasheet revisions to ensure pinout consistency. Validate operating temperature ranges for your specific environment. Check for alternative packages if surface-mount constraints change.

Selection Notes

Choose this component when bipolar stepper motors require integrated control and power driving in a compact surface-mount form factor. It suits designs needing LS-TTL compatibility and wide voltage tolerance. Consider thermal management capabilities given the high junction temperature rating. Evaluate current requirements against the 1.5A limit. Ensure system architecture aligns with its monostable and alarm output features.

Part Context

Part of the TEA3718 family, this IC combines logic input, current sensing, and output stages into a single unit. It simplifies stepper motor control by reducing external component count. The series is known for robust performance in industrial automation and precision positioning tasks requiring reliable bipolar drive.
