Overview
The NJM3771FM2-TE3 is a bipolar stepper motor driver manufactured by Nisshinbo Micro Devices Inc. It operates with a supply voltage range of 4.75V to 5.25V and supports load voltages from 10V to 40V. The device delivers an output current of 650mA and features a parallel interface with full integration of control and power stages. It utilizes a 28-PLCC package and functions within a junction temperature range of -20°C to 125°C.
Feature Summary
- Integrates LS-TTL compatible logic input stage, current sensor, monostable multivibrator, and high-power H-bridge output stage with built-in protection diodes.
- Supports full-step and half-step resolution modes for precise stepper motor control.
- Provides complete drive functionality including control logic and power stages in a single integrated circuit.
Applications
- General-purpose stepper motor control systems
- Automation equipment requiring bipolar stepper drivers
- Industrial motion control applications
Procurement Notes
This component is officially discontinued and no longer in active production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Confirm the specific suffix TE3 matches required packaging formats such as cut tape or reel when sourcing replacements. Ensure compatibility with existing system designs before procurement due to end-of-life status.
Selection Notes
Select this part for applications requiring a fully integrated bipolar stepper driver with a 650mA output capability. It is suitable for systems operating within a 10V to 40V load voltage range and requires a 5V logic supply. The 28-PLCC package is appropriate for surface-mount assembly. Consider alternative components if long-term supply stability is critical, as this model is discontinued.
Part Context
The NJM3771 series represents a line of bipolar stepper motor drivers designed for general-purpose applications. The NJM3771FM2 variant specifically offers a 650mA output current and integrates both control and power stages. It is pin-compatible with other variants in the family but differs in output specifications and package type compared to higher-current models like the NJM37717.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, verify functional equivalence with other bipolar stepper drivers offering similar current ratings and package dimensions.
