Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate restricted availability or discontinuation status. Verify current stock levels and obsolescence notices directly with authorized suppliers before design finalization. Alternative sourcing strategies should be evaluated immediately due to the discontinued production status.

Selection Notes

Select this part when a fully integrated solution for bipolar stepper motors is required without external logic components. Ensure the application voltage remains within the 10 V to 45 V limit. Consider the PLCC-28 package constraints for PCB layout. Verify thermal management capabilities for the specified operating temperature range of -40°C to +125°C during system design.

Part Context

The NJM3770 series represents a family of integrated stepper motor drivers designed for general applications. This specific variant utilizes the AFM2 suffix to denote the PLCC-28 surface mount package configuration. It belongs to the broader PMIC category under motor controllers and drivers, providing a compact alternative to discrete driver implementations.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, direct pin-to-pin replacements may require verification against updated datasheets from other manufacturers or evaluation of legacy inventory sources.
