Overview
The TEA3718DP is a bipolar stepper motor driver from STMicroelectronics, housed in a 16-pin PDIP package. It operates within a supply voltage range of 10 V to 50 V and supports a maximum IGBT collector current of 1.5 A. The device features LS-TTL compatible logic inputs and includes built-in protection diodes. Designed for unstabilized motor supplies, it offers thermal overload protection and a typical switching frequency of 30 kHz. Operating temperatures range from 0°C to 70°C.
Feature Summary
- Supports half-step and full-step modes for precise motor control
- Includes alarm output or pre-alarm output capabilities
- Features wide current control ranging from 5 mA to 1500 mA
- Provides thermal overload protection for system reliability
Applications
- LS-TTL controlled stepper motor systems
- Microprocessor-controlled stepper motor drives
- Bipolar stepper motor applications requiring maximum performance
Procurement Notes
Verify the specific suffix (e.g., DP) against the manufacturer datasheet to confirm pinout and package dimensions. Ensure the ordering code matches the required through-hole configuration. Cross-reference the component marking with official STMicroelectronics documentation to prevent counterfeit parts. Confirm RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when designing bipolar stepper motor drivers requiring a wide voltage range up to 50 V. It is suitable for systems needing integrated thermal protection and alarm outputs. Consider the 1.5 A current limit and 16-pin PDIP package constraints during PCB layout. Verify compatibility with LS-TTL logic levels for direct interfacing without additional level shifting.
Part Context
The TEA3718 belongs to the TEA3718 series of active stepper motor drivers. Two ICs typically form a complete drive unit with minimal external components. This series is designed for robust operation in industrial environments, offering high performance for bipolar motors while maintaining simplicity in circuit design and integration.
Replacement Considerations
Consult the official datasheet for direct pin-to-pin replacements. Verify that any substitute maintains the 10-50 V operating range and 1.5 A current capability. Ensure the alternative component supports bipolar drive modes and LS-TTL input compatibility.
