NJM3771E3-TE2

Overview

The NJM3771E3-TE2 is a bipolar stepper motor driver manufactured by Nisshinbo Micro Devices Inc. It integrates logic input, current sensing, monostable multivibrator, and high-power H-bridge output stages with built-in protection diodes. Designed for general applications, it supports bipolar stepper motors with parallel interface control. The device operates on a supply voltage of 4.75V to 5.25V and handles load voltages from 10V to 45V. It delivers an output current up to 1200mA and functions within a junction temperature range of -20°C to +125°C. The component is housed in a surface-mount EMP-24 package.

Feature Summary

• Full integration of control and power stages including LS-TTL compatible logic inputs and current sensors
• High-voltage H-bridge output stage with built-in protection diodes
• Supports full-step and half-step resolution modes

Applications

• General purpose bipolar stepper motor systems
• Integrated control and drive units requiring compact design
• Automation equipment utilizing stepper motion control

Procurement Notes

Verify the specific suffix TE2 against official datasheets to confirm reel packaging specifications. Confirm end-of-life status as distribution sources indicate discontinuation. Ensure compatibility with existing LS-TTL logic levels and verify thermal management requirements for the EMP-24 package under maximum operating temperatures.

Selection Notes

Select this component when a fully integrated bipolar stepper driver is required with high voltage tolerance. It serves as a pin-compatible alternative to the NJM3717 series but offers higher output current capabilities. Consider the EMP-24 surface mount package for space-constrained designs requiring robust protection features and simple parallel interface control.

Part Context

This part belongs to the NJM3771 series of stepper motor drivers from Nisshinbo Micro Devices. It is a high-voltage version designed to replace or complement earlier models like the NJM3717. The series focuses on providing complete drive solutions with minimal external components, integrating both logic and power stages into a single IC for efficient motor control applications.

Replacement Considerations

Public documentation confirms pin compatibility with the NJM3717 series. Verify if the NJM3771D2 or NJM3777E3 meet specific current or voltage requirements, noting differences in output configuration and package type.
