Overview
The TEA3718SFPTR is a bipolar stepper motor driver from STMicroelectronics, designed for LS-TTL or microprocessor-controlled systems. It integrates an LS-TTL compatible logic input, current sensor, monostable, and output stage with built-in protection diodes. The device supports half-step and full-step modes, featuring thermal overload protection and wide voltage range operation from 10V to 50V. It offers continuous current control from 5mA to 1500mA and operates within a temperature range of 0°C to 70°C.
Feature Summary
- Integrates LS-TTL compatible logic input and current sensor for precise control
- Supports both half-step and full-step operating modes for flexible positioning
- Includes built-in protection diodes and thermal overload protection mechanisms
Applications
- LS-TTL controlled stepper motor systems
- Microprocessor-controlled stepper motor applications
- Bipolar drive configurations requiring maximum motor performance
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm the active status and RoHS compliance through official manufacturer documentation. Ensure compatibility with the required supply voltage range and current settings before procurement.
Selection Notes
Select this component for applications requiring integrated bipolar drive capabilities with built-in protection features. Consider the 10V to 50V operating range and up to 1.5A output current when matching motor specifications. Verify interface compatibility with LS-TTL logic levels in the system design.
Part Context
The TEA3718 series serves as a complete control and drive unit solution when paired with external components. It is part of STMicroelectronics' portfolio for stepper motor control, offering a robust alternative to discrete solutions by integrating essential driver functions into a single IC package.
Replacement Considerations
Consult official substitution lists for direct replacements. Verify pinout compatibility and electrical parameter equivalence if considering alternative stepper motor drivers from other manufacturers.
