LV8549MC-BH

Overview

The LV8549MC-BH is a monolithic linear integrated circuit designed as a stepper motor driver. It features DMOS output transistors with a typical total on-resistance of 1Ω, supporting a maximum supply voltage of 20V and a peak output current of 1A. The device operates within a supply voltage range of 4V to 16V and consumes a typical operating supply current of 65µA. It is housed in a compact SOIC-10 surface-mount package with dimensions of 4.9mm x 3.9mm x 1.5mm. The component functions reliably across an extended temperature range from -30°C to +85°C.

Feature Summary

• Integrates DMOS output transistors for low saturation voltage drive performance
• Operates from a single power supply without requiring separate control system power
• Designed for full-step motor drive applications in 12V systems

Applications

• Full-step stepper motor drive in 12V system products
• Compact electromechanical devices requiring single-supply operation
• Low-power motion control modules

Procurement Notes

Verify the specific suffix against official datasheets to confirm electrical characteristics, as variations may exist within the family. Confirm RoHS compliance status through manufacturer documentation prior to integration. Check for end-of-life notices or obsolescence warnings to ensure long-term availability for production cycles.

Selection Notes

Select this component for designs requiring a single-supply stepper driver with minimal external components. The low quiescent current makes it suitable for battery-operated or energy-efficient applications. Ensure the thermal design accommodates the power dissipation limits within the SOIC-10 package during continuous operation.
