NJM3717E2

Overview

The NJM3717E2 is a bipolar stepper motor driver manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range of 4.75 V to 5.25 V and supports load voltages up to 40 V. The device features a 20-pin EMP surface-mount package with dimensions of 12.8 x 7.5 x 2.3 mm. It draws 25 mA of operating current and functions across a temperature range of -20 °C to +125 °C. The component provides full integration of control and power stages for unipolar or bipolar stepper motors.

Feature Summary

• Integrates complete control logic and power output stages for stepper motor applications
• Supports bipolar output configurations for precise motor control
• Designed for surface-mount installation in compact electronic assemblies

Applications

• Stepper motor control systems
• Motion control circuits
• Industrial automation equipment

Procurement Notes

Verify the End-of-Life (EOL) status before procurement, as multiple sources indicate this specific part number is discontinued. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints and design specifications given the component's discontinuation status.

Selection Notes

Select this component only if the 20-pin EMP package and 5V logic interface match the design requirements. Consider the 40V load voltage limit and 1A output capability when sizing the motor. Evaluate alternative drivers from the same series if lead times are critical due to the EOL status.

Part Context

This component belongs to the NJM3717 series of stepper motor drivers. It shares functional similarities with the NJM3717D2, which utilizes a 16-DIP through-hole package instead of the EMP surface-mount format. Both variants offer integrated control and power stages for stepper motor applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official manufacturer resources for valid replacement options.
