LV8740V-TLM-E

Overview

The LV8740V-TLM-E is a fully integrated Bi-CMOS stepper motor driver manufactured by onsemi. It operates with 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 features four half-bridge outputs capable of delivering up to 1.5 A per channel. It offers selectable step resolutions including full, half, and quarter stepping. The component is housed in a 44-pin LSSOP package with an exposed pad for thermal management.

Feature Summary

• Fully integrated control and power stage design
• Supports bipolar stepper motors and brushed DC motors
• Selectable step resolution modes

Applications

• General purpose stepper motor control
• Office automation equipment
• Industrial motion control systems

Procurement Notes

Verify the specific suffix TLM-E against current manufacturer documentation to confirm package type and RoHS compliance status. Confirm availability as distribution channels may list this part as obsolete or end-of-life. Ensure the ordering information matches the exact electrical specifications required for the target application before finalizing procurement.

Selection Notes

Select this component when a single-chip solution for bipolar stepper motors is required. It is suitable for applications needing integrated logic and power stages within a compact SSOP footprint. Verify that the input voltage and load voltage ranges align with the system power architecture. Consider the thermal performance provided by the exposed pad design for high-current operations.

Part Context

This part belongs to the LV8740 family of motor drivers designed for general-purpose applications. It shares functional similarities with the LV8741 but may differ in specific pin configurations or feature sets. The series targets cost-sensitive designs requiring reliable stepper motor control without external discrete components.

Replacement Considerations

The LV8741V-TLM-E is a related variant within the same product family. Verify pin compatibility and specific feature differences before substitution. Check for any changes in operating temperature ranges or current capabilities between the two models.
