• General purpose motor control systems

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to discontinuation notices. Confirm package integrity and pin alignment against the EMP-20 specification before assembly. Review the latest datasheet for any revisions or environmental compliance updates prior to final design approval.

Selection Notes

Select this component for designs requiring a fully integrated bipolar stepper driver with LS-TTL compatibility. Ensure the application voltage remains within the 4.75 V to 5.25 V supply range. Consider the EMP-20 surface mount package constraints and thermal management requirements for the specified operating temperature range.

Part Context

This component belongs to the NJM3717 series of stepper motor drivers. It is designed to replace older discrete solutions by integrating logic, sensing, and power stages into a single IC. The E2 suffix typically denotes specific packaging or tape-and-reel configurations for automated assembly processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official manufacturer notifications for end-of-life guidance or recommended alternatives if discontinuation occurs.
