NJM2670D2

Overview

The NJM2670D2 is a fully integrated bipolar motor driver IC designed for controlling bipolar stepper motors and brushed DC motors. It features a parallel interface and includes four half-bridge output configurations within a single package. The device operates with a wide supply voltage range, supporting dual supplies from ±2V to ±18V. It integrates control logic and power stages to simplify system design. The component is housed in a 22-pin DIP package, suitable for through-hole mounting on printed circuit boards.

Feature Summary

• Fully integrated driver combining control logic and power stage
• Supports both bipolar stepper and brushed DC motor types
• Utilizes a standard parallel interface for command input

Applications

• Bipolar stepper motor control systems
• Brushed DC motor drive applications
• Industrial automation equipment requiring motor actuation

Procurement Notes

Verify the specific suffix 'D2' against official Nisshinbo Micro Devices documentation to confirm pinout and thermal characteristics. Ensure the supplier provides valid traceability for automotive or industrial grade requirements if applicable. Cross-reference the 22-pin DIP package dimensions with your PCB footprint library before finalizing procurement orders.

Selection Notes

Select this component when a combined control and power solution is required for bipolar motors without external gate drivers. The parallel interface simplifies microcontroller connection compared to serial protocols. Consider the thermal performance of the DIP package for high-current applications, as heat dissipation may require additional board space or heatsinking compared to surface-mount alternatives.
