LMD18201T

Overview

The LMD18201T is a bipolar motor driver manufactured by Texas Instruments, designed for motion control applications. It integrates Bi-CMOS and DMOS technologies on a single monolithic structure to provide full-featured control and power stages. The device features two half-bridge outputs capable of delivering a continuous output current of 3 A with peak currents up to 6 A. It operates within a supply voltage range of 12 V to 55 V and supports both brushed DC and bipolar stepper motors. The component is housed in a TO-220-11 through-hole package and functions across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates Bi-CMOS control circuitry with DMOS power devices for compact design
• Provides dual half-bridge configuration suitable for H-bridge motor driving
• Supports parallel interface for straightforward logic control integration

Applications

• Brushed DC motor control systems
• Bipolar stepper motor drivers
• General-purpose motion control circuits

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering, distinct from tube variants. Confirm RoHS compliance status as 'NOPB' versions are explicitly compliant, while standard suffixes may vary. Check lead times due to potential long delivery periods associated with this component family. Ensure thermal management solutions match the TO-220-11 package requirements for high-current operation.

Selection Notes

Select the LMD18201T for applications requiring integrated control and power stages without external logic. It is suitable for designs needing 3 A continuous current handling. Consider the TO-220-11 package for through-hole mounting needs. Evaluate thermal dissipation capabilities given the power dissipation limits. Compare against LMD18200 if lower current or different packaging is required.

Part Context

This component belongs to the LMD18201 series of motor drivers from Texas Instruments. It is part of the broader PMIC category focusing on motor and motion controllers. The device complements similar parts like the LMD18200, offering specific integration levels for industrial and consumer automation tasks.

Replacement Considerations

LMD18200T/NOPB serves as a parameter-equivalent substitute within the same product family.
