LV8549MC-AH

Overview

The LV8549MC-AH is a monolithic linear integrated circuit designed as a stepper motor driver. It features DMOS output transistors with a typical total on-resistance of 1 ohm. The device operates within a supply voltage range of 4 V to 16 V and supports a maximum output current of 1 A. It functions optimally for full-step motor drive in 12 V system products. The component utilizes a single power supply configuration, eliminating the need for a separate control system power supply. It is housed in a compact SOIC-10 package.

Feature Summary

• Utilizes DMOS output transistors for low saturation voltage performance
• Operates from a single power supply without requiring separate control voltage
• Designed specifically for full-step motor drive applications

Applications

• Full-step stepper motor drive systems
• 12V system product motor control
• General DC motor driving

Procurement Notes
