LV8044LP-TLM-E

Overview

The LV8044LP-TLM-E is a stepper motor driver manufactured by onsemi, designed for compact motion control applications. It features a half-bridge output configuration with three independent outputs and supports a load voltage range of 2.7 V to 5.5 V. The device operates within an ambient temperature range of -20°C to +85°C and draws a typical operating supply current of 3 mA. Packaged in a QFN-40 (VQLP) surface-mount format measuring 5 mm x 5 mm x 0.85 mm, it integrates protection mechanisms including overcurrent and thermal shutdown. The component is classified under Motor / Motion / Ignition Controllers & Drivers.

Feature Summary

• Integrates three half-bridge outputs for driving stepper motors
• Includes built-in overcurrent and thermal protection circuits
• Supports low-power operation with minimal standby current consumption

Applications

• Stepper motor control in consumer electronics
• Motion control systems in office automation equipment
• Compact actuator drivers in home appliances

Procurement Notes

Verify the specific suffix TLM-E against official datasheets to confirm package and tape-and-reel specifications. Confirm end-of-life status and availability through authorized distributors. Ensure compliance with RoHS directives and humidity sensitivity level requirements during storage and handling. Validate that the QFN-40 footprint matches the target PCB design constraints.

Selection Notes

Select this component when a low-voltage, multi-output stepper driver is required for space-constrained designs. Consider the 3 mA supply current for battery-operated or energy-efficient systems. Evaluate the QFN-40 package for thermal performance and soldering reliability. Compare against alternative half-bridge drivers if higher current capacity or different voltage ranges are needed.

Part Context

The LV8044LP series belongs to onsemi's portfolio of multimedia and motor control integrated circuits. These devices are engineered for high integration and low power consumption, targeting portable and compact electronic systems. The LV8044LP specifically addresses the need for precise stepper motor control in small form-factor applications without requiring external discrete components for basic protection functions.

Replacement Considerations

Check for direct pin-compatible substitutes within the LV8044LP family, such as LV8044LP-TLM-H. Verify electrical parameters and package dimensions before substitution. Consult manufacturer documentation for any functional differences between suffix variants.
