LV8740V-MPB-E

Overview

The LV8740V-MPB-E is a bipolar stepper motor driver manufactured by onsemi, designed for precise motion control applications. It operates within a supply voltage range of 9 V to 35 V and supports output currents up to 3 A. The device integrates advanced features such as microstepping resolution options including 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, and 1/128 steps. It utilizes a 44-pin SSOP package suitable for surface mount technology. The component functions as a dedicated stepping motor driver within the power management IC category.

Feature Summary

• Supports variable microstepping resolutions from full step to 1/128 step for smooth motor operation
• Integrates protection mechanisms against over-temperature and over-current conditions
• Capable of driving bipolar stepper motors with high current output capability

Applications

• Bi-polar stepper motor control systems
• Precision positioning equipment
• Automated machinery drives

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the datasheet. Validate package integrity upon receipt to prevent handling damage.

Selection Notes

Select this component when designing systems requiring high-resolution microstepping for bipolar stepper motors. Consider the 9 V to 35 V input range compatibility with existing power supplies. Evaluate thermal management needs due to 3 A output capability. Verify interface signal levels match the host controller logic standards.

Part Context

This part belongs to the LV8740 series of stepper motor drivers from onsemi. It is distinct from evaluation boards like the LV8740VGEVB, which are development tools rather than production components. The MPB suffix indicates the specific tape and reel packaging configuration used for automated assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official cross-reference guides or contact the manufacturer for qualified alternatives if this component is obsolete or unavailable.
