LV8702V-MPB-H

Overview

The LV8702V-MPB-H is a bipolar stepper motor driver manufactured by onsemi, designed for general-purpose motion control applications. It integrates full control and power stages within a single BiCDMOS technology package. The device supports a supply voltage range of 0V to 5.5V for logic and operates with load voltages between 9V and 32V. It delivers an output current of 2.5A per phase and features four half-bridge outputs. The component utilizes a parallel interface and offers selectable stepping resolutions including full, half, and quarter step modes. It is housed in a 44-LSSOP package with exposed pad (44-SSOPJ-EP) for surface mount installation.

Feature Summary

• Integrates full control and power stages for bipolar stepper motors using BiCDMOS technology
• Supports micro-stepping via single pulse signal input for smooth high-speed rotation
• Features high-efficiency drive that adjusts current based on motor load and speed
• Includes thermal shutdown circuitry for protection

Applications

• Printer and plotter mechanisms
• Textile machinery
• General purpose motor control systems

Procurement Notes

Verify the specific suffix MPB-H against official datasheets to confirm packaging type and moisture sensitivity level. Confirm end-of-life status as distribution channels may list obsolete inventory. Ensure ESD handling protocols are followed due to humidity sensitivity classification. Cross-reference pinout diagrams with target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fully integrated bipolar stepper driver is required with support for micro-stepping operations. It is suitable for designs needing a wide load voltage range up to 32V and moderate current output. Consider the 44-pin SSOPJ package constraints for board space. Verify compatibility with parallel interface controllers if digital control signals are used directly without additional logic buffers.

Part Context

This part belongs to the LV8702V series of motor drivers from onsemi. It is distinct from evaluation boards like the LV8702VGEVB or development kits such as the LV8702VSLDGEVK. The MPB-H suffix indicates a specific tube packaging configuration. It serves as the core integrated circuit for building custom motor control solutions rather than a standalone development tool.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Check manufacturer announcements for direct replacements or updated series components.
