Overview
The E-TEA3718DP is a bipolar stepper motor driver from the TEA3718 series, manufactured by STMicroelectronics. It features a 16-pin PDIP package designed for through-hole installation. The device supports a wide supply voltage range of 10 V to 50 V and delivers a maximum IGBT collector current of 1.5 A. It operates within a temperature range of 0°C to 70°C and includes built-in protection diodes.
Feature Summary
- Supports half-step and full-step modes for precise motor control
- Includes thermal overload protection mechanisms
- Features LS-TTL compatible logic inputs
- Provides alarm or pre-alarm output capabilities
Applications
- LS-TTL controlled stepper motor systems
- Microprocessor-controlled stepper motor applications
- General purpose bipolar stepper motor drive units
Procurement Notes
Verify the specific suffix 'DP' against official STMicroelectronics documentation to confirm pinout and package dimensions. Ensure compatibility with system voltage requirements between 10 V and 50 V. Confirm that the through-hole PDIP format aligns with PCB layout constraints. Check for any obsolescence notices regarding this specific variant.
Selection Notes
Select this component when a robust bipolar stepper driver with integrated protection is required. It is suitable for designs utilizing LS-TTL logic interfaces. Consider the 1.5 A current limit and 50 V maximum voltage rating during circuit design. Verify that the operating temperature range meets environmental specifications.
Part Context
This part belongs to the TEA3718 family of stepper motor drivers. These circuits typically consist of an LS-TTL compatible logic input, a current sensor, a monostable, and an output stage. Two ICs are often used together with external components to form a complete control and drive unit for stepper motors.
Replacement Considerations
The TEA3718SDP is listed as a discontinued equivalent. Verify functional compatibility before substitution. No other active substitutes are confirmed in the provided data.
