E-TEA3718SDP

Overview

The E-TEA3718SDP is a bipolar stepper motor driver manufactured by STMicroelectronics, housed in a 16-PowerDIP 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. It features LS-TTL compatible inputs, half-step and full-step modes, and built-in protection diodes.

Feature Summary

• Integrates LS-TTL compatible logic input, current sensor, monostable, and output stage with protection diodes
• Supports both half-step and full-step operation modes for bipolar stepper motors
• Includes thermal overload protection and alarm or pre-alarm output capabilities

Applications

• LS-TTL controlled stepper motor systems
• Microprocessor-controlled stepper motor drives
• General purpose bipolar stepper motor applications

Procurement Notes

Verify component authenticity through authorized channels as the TEA3718 series may have end-of-life status. Confirm package integrity and pin alignment against the 16-PowerDIP specification. Ensure logic levels match LS-TTL requirements before integration into existing designs.

Selection Notes

Select this component for designs requiring integrated control and power stages for bipolar stepper motors. Verify that the 1.5A output current meets load requirements and that the 10V to 45V supply range aligns with the motor specifications. Consider the 16-PowerDIP package constraints for PCB layout.

Part Context

The E-TEA3718SDP belongs to the TEA3718 family of stepper motor drivers from STMicroelectronics. This series provides complete control and drive units when paired with minimal external components. The device is designed for unstabilized motor supply voltages and offers wide current control ranges.

Replacement Considerations

E-TEA3718DP is listed as an equivalent part number for the TEA3718 series.
