NJM3517D2

Overview

The NJM3517D2 is a unipolar stepper motor driver manufactured by Nisshinbo Micro Devices Inc. It integrates logic input, current sensing, and power output stages in a 16-pin DIP package. The device supports step resolutions of 1 and 1/2. It operates with a supply voltage range of 4.75V to 5.25V and handles load voltages from 10V to 45V. The maximum output current is 1A. The operating temperature range extends from -20°C to 125°C (TJ).

Feature Summary

• Integrates LS-TTL compatible logic input stage for direct interface.
• Includes built-in current sensor and monostable multivibrator.
• Features high-power H-bridge output stage with protection diodes.

Applications

• General purpose stepper motor control systems
• Industrial automation equipment
• Motion control applications

Procurement Notes

Verify the specific manufacturer source, as documentation lists both New Japan Radio Co Ltd and Nisshinbo Micro Devices Inc. Confirm the exact package dimensions and pinout against the official datasheet before integration. Ensure supply voltage constraints are strictly met to prevent device damage.

Selection Notes

Select this component for unipolar stepper motor applications requiring integrated control and power stages. Verify compatibility with LS-TTL logic levels. Consider the 16-DIP package for through-hole mounting requirements. Check thermal performance within the specified junction temperature limits.

Part Context

This part belongs to the NJM3517 series of stepper motor drivers. It is distinct from the NJM3717, which is designed for bipolar motors. The NJM3517D2 specifically targets unipolar configurations with a 16-DIP form factor.
