Overview
The E-TEA3718SFP is a bipolar stepper motor driver manufactured by STMicroelectronics, designed for LS-TTL or microprocessor-controlled systems. It features a 20-SO surface-mount package and operates with a supply voltage range of 4.75V to 5.25V for logic and 10V to 45V for the motor load. The device delivers an output current of 1.5A per channel and supports full-step and half-step modes. It includes built-in protection diodes, thermal overload protection, and alarm outputs.
Feature Summary
- Integrates LS-TTL compatible logic inputs, current sensors, monostables, and output stages with built-in protection diodes.
- Supports both full-step and half-step operation modes for precise stepper motor control.
- Features wide voltage tolerance for unstabilized motor supply voltages ranging from 10V to 50V.
- Includes thermal overload protection and configurable alarm or pre-alarm outputs.
Applications
- LS-TTL controlled stepper motor systems
- Microprocessor-driven motion control applications
- Bipolar stepper motor drive units
Procurement Notes
Verify the specific suffix 'SFP' against official STMicroelectronics documentation to confirm the exact package type and pinout configuration. Ensure compatibility with LS-TTL logic levels in your design. Check for RoHS compliance status as indicated in the latest datasheet revisions before finalizing procurement specifications.
Selection Notes
Select this component when a fully integrated bipolar stepper driver with LS-TTL interface is required. It is suitable for designs needing continuous or stepped current control between 5mA and 1500mA. Consider the 20-SO package for surface-mount assembly requirements and verify that the operating temperature range meets your environmental constraints.
Part Context
The TEA3718 series consists of circuits forming complete control and drive units for stepper motors. Two ICs typically form a full bridge. The E-prefix variant often denotes an enhanced or specific manufacturing version within the TEA3718 family, maintaining core functionality while potentially differing in packaging or specific electrical tolerances defined by the manufacturer.
Replacement Considerations
E-TEA3718SDP is listed as a substitute part number in distributor databases. Verify pin-to-pin compatibility and electrical specifications against the official datasheet before substitution. No other direct public substitutes are confirmed in the provided source material.
