NJM3773E3

Overview

The NJM3773E3 is a bipolar stepper motor driver manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range of 10 V to 45 V and draws a quiescent current between 55 mA and 70 mA. The device supports step resolutions of full-step and half-step modes. It is housed in an EMP-24 surface-mount package and functions across an extended temperature range from -40°C to +150°C.

Feature Summary

• Integrated control and power stages for bipolar stepper motors
• Supports full-step and half-step resolution modes
• Wide operating temperature capability up to 150°C

Applications

• Bipolar stepper motor control systems
• Industrial motion control applications
• General-purpose motor driver circuits

Procurement Notes

Verify component authenticity through authorized channels, as the NJM3773E3 is listed as an End-of-Life product. Confirm that the EMP-24 package matches design requirements and check RoHS compliance documentation before integration into new designs.

Selection Notes

Select this component for bipolar stepper motor applications requiring integrated drive capabilities. Ensure the system voltage falls within the 10 V to 45 V range and verify that the EMP-24 surface-mount footprint fits the PCB layout constraints.

Part Context

This part belongs to the NJM3773 series of stepper motor drivers. It shares functional similarities with other variants like the NJM3773D2, though package types differ. The series provides integrated solutions for controlling bipolar stepper motors without external power transistors.
