Procurement Notes

This component is officially listed as discontinued or inactive by the manufacturer. Verification of final availability requires checking specific distributor status codes. Sourcing should focus on identifying valid surplus stock or authorized replacement alternatives. Confirm RoHS compliance status through official documentation before procurement planning.

Selection Notes

Select this part for applications requiring integrated bipolar stepper driving with parallel interface compatibility. Verify that the system load voltage remains within the 10V to 40V range and the logic supply fits the 4.75V to 5.25V specification. Ensure thermal management accommodates the specified junction temperature limits during operation.

Part Context

The NJM3770AFM2 belongs to the NJM3770 series of stepper motor controllers. This family includes variants such as NJM3770AD3 and NJM3770AFM2-TE3. These devices share similar functional architectures but differ in packaging types and specific electrical characteristics. The series targets general-purpose motion control applications.

Replacement Considerations

Official substitutes include NJM3770AFM2-TE3 and NJM3770AD3. Verify pinout compatibility and electrical specifications against the original design requirements when considering these alternatives.
