LV8063FA-BH

Overview

The LV8063FA-BH is a single-phase full-wave motor driver manufactured by onsemi. It operates within an input voltage range of 2.2 V to 6 V and supports 10-step microstepping control for precise positioning. The device integrates high-side and low-side MOSFETs to drive inductive loads such as stepper motors. It features built-in protection mechanisms including overcurrent, thermal shutdown, and undervoltage lockout. The component is designed for applications requiring compact form factors and efficient motor control with minimal external components.

Feature Summary

• Integrates dual-channel MOSFET drivers for single-phase full-wave operation
• Supports 10-step microstepping resolution for smooth motor movement
• Includes comprehensive protection against overcurrent, overheating, and low voltage conditions

Applications

• Precision stepper motor control in consumer electronics
• Actuator drives in office automation equipment
• Compact motor management systems in portable devices

Procurement Notes

Verify the specific suffix BH against official onsemi documentation to confirm pinout and thermal characteristics. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure compatibility with your system's logic voltage levels before integration. Request updated datasheets directly from the manufacturer to validate current manufacturing specifications.

Selection Notes

Select this component when a compact solution for single-phase stepper motors is required within a 6 V supply limit. The integrated microstepping capability reduces mechanical resonance compared to full-step driving. Consider the SOP-8 package constraints for thermal management in enclosed designs. Verify that the 2.2 V minimum operating voltage aligns with your battery or power rail specifications.

Part Context

This part belongs to onsemi's LV8063 series of motor drivers, which are optimized for low-voltage applications. The series focuses on integrating control logic and power stages into a single small-footprint package. It targets markets demanding high precision in small form-factor devices where space and power efficiency are critical design parameters.

Replacement Considerations

Check for direct cross-reference part numbers in onsemi's official substitution guides. Verify pin-to-pin compatibility if considering alternative manufacturers. Ensure the replacement supports the same 10-step microstepping interface and voltage range.
