NJU39610D2

Overview

The NJU39610D2 is a bipolar stepper motor driver IC manufactured by Nisshinbo Micro Devices Inc. It operates within a supply voltage range of 4.75V to 5.25V and supports step resolutions greater than 256 microsteps. The component features a parallel interface and includes four half-bridge pre-drivers for output configuration. It provides controller functions for commutation and direction management. The device is housed in a 22-DIP package with a width of 10.16mm (0.400 inches) and utilizes through-hole mounting. It is rated for an operating temperature range of -20°C to 85°C.

Feature Summary

• Integrated controller functionality for precise commutation and direction management of bipolar stepper motors.
• Supports high-resolution stepping with capabilities exceeding 256 microsteps for smooth motion control.
• Includes four integrated half-bridge pre-drivers to facilitate direct connection to motor coils.

Applications

• General-purpose industrial automation equipment
• Factory automation systems requiring precise positioning
• Social infrastructure devices

Procurement Notes

This component has been officially discontinued as of March 2019, according to Product Change Notification documents from Nisshinbo Micro Devices. Availability is restricted to existing stock or secondary market sources. Designers must verify the inactive status before initiating new projects. Sourcing should focus on legacy inventory validation rather than standard manufacturing orders.

Selection Notes

Engineers selecting this part must account for its discontinuation status when planning long-term production runs. The specific 22-DIP through-hole package limits compatibility with surface-mount assembly processes. Verification of the 4.75V to 5.25V supply requirement is essential for system power design. Alternative solutions should be evaluated if future scalability or continuous supply is required for the application.
