NJM3773FM2-TE3

Overview

The NJM3773FM2-TE3 is a dual bipolar stepper motor driver manufactured by Nisshinbo Micro Devices Inc. It integrates control logic and power stages into a single fully integrated circuit. The device operates within a supply voltage range of 10 V to 45 V and supports step resolutions of 1/1 and 1/2. It utilizes a parallel interface for command input and features an SMD/SMT installation style in a PLCC-28 package. The component functions reliably across a temperature range of -40°C to +150°C, with a typical operating supply current between 60 mA and 75 mA.

Feature Summary

• Fully integrated design combining control and power stage functionality
• Supports bipolar stepper motors with 1/1 and 1/2 step resolution options
• Parallel interface for straightforward digital control integration

Applications

• General purpose stepper motor control systems
• Industrial automation equipment requiring dual axis control
• Motion control applications utilizing bipolar stepper motors

Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of availability should be conducted through authorized distributors or secondary market suppliers. Ensure that any sourced units are genuine and match the specific TE3 suffix requirements for tape and reel packaging compatibility. Cross-reference part numbers carefully to confirm functional equivalence if substituting.

Selection Notes

Select this component when a fully integrated solution for dual bipolar stepper motors is required without external discrete drivers. The PLCC-28 package suits surface mount assembly processes. Verify that the system voltage falls within the 10 V to 45 V range and that the thermal environment supports operation up to 150°C. The parallel interface requirement must align with the host controller's output capabilities.

Part Context

The NJM3773 series represents Nisshinbo Micro Devices' offering in the motor driver segment, specifically targeting bipolar stepper applications. This model belongs to the broader PMIC category but functions distinctly as a motion controller. It shares architectural similarities with other models in the NJM377x family, such as the NJM3772 and NJM3773D2, though package and pinout configurations vary significantly between DIP and PLCC variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The NJM3773D2 and NJM3772FM2-TE3 are related models within the same product line but differ in package type (DIP vs. PLCC) and specific electrical characteristics. Direct replacement requires careful evaluation of pin compatibility and mounting constraints.
