LV8741V-MPB-E

Overview

The LV8741V-MPB-E is a bipolar stepper motor driver manufactured by onsemi, utilizing Bi-CMOS technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports load voltages from 9.5 V to 35 V. The device provides an output current of 1.5 A and features four half-bridge outputs. It offers selectable step resolutions including full, half, and quarter stepping. The component is housed in a 44-pin SSOP package with a bare pad for thermal management and functions as a fully integrated controller and power stage.

Feature Summary

• Fully integrated design combining control logic and power stages
• Supports multiple step resolutions for precise motion control
• Bi-CMOS technology for efficient operation

Applications

• General purpose stepper motor driving
• Motion control systems
• Industrial automation equipment

Procurement Notes

Verify the specific MPB-E suffix against official documentation to confirm packaging details, as this variant may differ from standard reel configurations. Confirm end-of-life status with the manufacturer or authorized distributors before finalizing procurement plans due to potential availability constraints.

Selection Notes

Select this component for applications requiring a compact, fully integrated bipolar stepper solution. Ensure the system load voltage remains within the 9.5 V to 35 V range and that the thermal requirements are met via the exposed pad in the 44-SSOPK package.

Part Context

This part belongs to the LV8741 family of stepper motor drivers. It shares core functional specifications with variants such as the LV8741V-TLM-E, differing primarily in packaging and shipping configuration. The device is designed for general-purpose applications requiring reliable bipolar stepper motor control.

Replacement Considerations

The LV8741V-TLM-E is a confirmed substitute part number within the same product family, offering identical electrical characteristics but potentially different packaging.
