NJM3771FM2

Overview

The NJM3771FM2 is a fully integrated bipolar stepper motor driver manufactured by Nisshinbo Micro Devices Inc. It operates with a supply voltage range of 4.75V to 5.25V and supports load voltages from 10V to 40V. The device delivers an output current of 650mA and features four half-bridge outputs. It accepts parallel interfaces and supports step resolutions of full and half-step modes. The component is housed in a 28-PLCC package and functions within a junction temperature range of -20°C to 125°C.

Feature Summary

• Fully integrated control and power stage for bipolar stepper motors
• Supports full-step and half-step resolution modes
• Parallel interface for direct logic connection

Applications

• General purpose stepper motor control systems
• Motion control applications requiring integrated driver solutions

Procurement Notes

Verify the active status of this component, as official distributor records indicate it may be classified as inactive or discontinued. Confirm availability through authorized channels before design finalization. Ensure the specific suffix matches the required package type. Cross-reference with the manufacturer's latest product change notifications to confirm current production status and compliance requirements.

Selection Notes

Select this component when a compact, fully integrated solution for bipolar stepper motors is required. It is suitable for applications needing 650mA output current with a 5V logic supply. Consider the 28-PLCC package constraints for PCB layout. Verify that the parallel interface meets the system's control signal requirements without additional decoding logic.

Part Context

This part belongs to the NJM3771 series of stepper motor drivers. It shares functional similarities with other devices in the family, such as the NJM3772 and NJM3773, which offer different current ratings or packaging options. The series provides integrated solutions for motion control, distinguishing itself by combining logic control and power driving stages in a single IC.
