LV8711T-TLM-H

Overview

The LV8711T-TLM-H is a bipolar stepper motor driver manufactured by onsemi, designed for low consumption and high efficiency. It operates with a supply voltage range of 2.7V to 5.5V and supports load voltages from 4V to 16V. The device delivers an output current of 800mA and features a parallel interface. Packaged in a 24-TSSOP (24-TFSOP) surface-mount case, it integrates full control and power stages using Bi-CMOS technology. The component functions as a complete driver with four half-bridge outputs.

Feature Summary

• Integrates full control logic and power stage circuitry into a single package
• Supports PWM constant-current control for efficient bipolar stepper motor operation
• Includes built-in protection mechanisms such as thermal shutdown and short-circuit protection

Applications

• Bipolar stepper motor control systems
• Power Over Ethernet (PoE) powered devices
• Industrial printer and plotter mechanisms
• General purpose motor control applications

Procurement Notes

Verify the obsolete status and end-of-life designation before finalizing design-in decisions. Confirm availability through authorized distributors or secondary market suppliers, as standard production may have ceased. Ensure that the 24-TSSOP package dimensions align with existing PCB footprints. Validate RoHS3 compliance requirements against specific regional regulations. Check for any pending product change notices that might affect long-term support.

Selection Notes

Select this component when a fully integrated solution for bipolar stepper motors is required within a compact form factor. The Bi-CMOS technology offers a balance between control precision and power handling capabilities. Consider the 2.7V to 5.5V logic supply range for compatibility with various microcontroller interfaces. The 4V to 16V load voltage range suits applications powered by multi-cell battery configurations or standard low-voltage DC sources.
