Procurement Notes

This component is listed as obsolete or discontinued by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verify current lifecycle status and lead times carefully before design-in. Alternative sourcing may require evaluating equivalent replacement parts from the same product family or compatible competitors.

Selection Notes

Select this part for applications requiring a compact dual-channel solution for bipolar stepper motors. Ensure the system load voltage falls within the 10V to 40V range and the logic supply is stable at 5V. Consider the high junction temperature rating for thermal management in enclosed spaces. Verify that the 24-pin EMP package fits the PCB footprint constraints.

Part Context

The NJM3775E3 belongs to the NJM377x series of motor drivers from Nisshinbo Micro Devices. This series focuses on integrated solutions for stepper motor control, combining gate drive and logic in a single IC. The E3 suffix typically denotes specific packaging or environmental compliance variations within the product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the NJM377x series or comparable dual H-bridge stepper drivers from Nisshinbo if pin compatibility is required.
