LMD18200T/LF14

Overview

The LMD18200T/LF14 is a bipolar stepper motor driver manufactured by Texas Instruments. It operates within a supply voltage range of 12V to 55V and delivers an output current of 3A. The device utilizes Bi-CMOS and DMOS technology to integrate control and power stages. It features a low-side output configuration with two channels, designed for through-hole mounting in a TO-220-11 package. The component supports junction temperatures up to 150°C.

Feature Summary

• Integrates Bi-CMOS control circuitry with DMOS power devices on a single monolithic structure
• Provides full integration of drive controls and power stages for bipolar stepper motors
• Features a low-side output configuration suitable for H-bridge applications

Applications

• Bipolar stepper motor control systems
• Motion control applications requiring integrated drive solutions
• General purpose motor driver circuits

Procurement Notes

Verify the specific LF14 suffix against official Texas Instruments documentation to confirm lead-free status and RoHS compliance details. Ensure the TO-220-11 package form matches design requirements. Cross-reference the part number with authorized distributors to confirm active status and availability constraints.

Selection Notes

Select this component for designs requiring a 3A continuous current capability at voltages up to 55V. The TO-220-11 package facilitates thermal management for high-power dissipation scenarios. Consider the low-side output topology when designing the load connection scheme compared to high-side alternatives.
