LMD18200-2D/883

Overview

The LMD18200-2D/883 is a high-voltage H-Bridge motor driver manufactured by Texas Instruments, designed for robust industrial and military applications. It integrates two half-bridge drivers to control brushed DC motors or bipolar stepper coils. The device supports a supply voltage range from 12 V to 55 V and delivers an output current of 3 A per channel. It operates within an extended temperature range of -55 °C to +125 °C and utilizes a ceramic dual-in-line package (CDIP) with 11 pins, ensuring reliability in harsh environments.

Feature Summary

• Integrates two half-bridge drivers into a single monolithic H-Bridge configuration for efficient motor control.
• Features internal clamp diodes to protect against inductive kickback from motor loads.
• Includes thermal shutdown circuitry to prevent damage during overtemperature conditions.
• Utilizes radiation-hardened design specifications suitable for aerospace and defense systems.

Applications

• Control of hydraulic pumps in aerospace actuation systems
• Drive circuits for linear actuators in military equipment
• Bipolar stepper motor control in satellite mechanisms
• High-reliability industrial motion control interfaces

Procurement Notes

Verify the specific suffix /883 indicates compliance with MIL-PRF-38534 or similar military standards. Confirm that the ceramic package variant meets required environmental testing protocols. Ensure ordering documentation specifies the exact lot traceability needed for defense contracts. Cross-reference the manufacturer's latest quality notifications for any process changes affecting qualified parts.

Selection Notes

Select this component when radiation hardness and extreme temperature stability are mandatory. The CDIP package provides superior mechanical strength compared to plastic variants. Consider the 3 A continuous current rating against peak load requirements. Verify that the 55 V maximum supply voltage aligns with the system power architecture. Evaluate thermal management needs given the integrated protection features.

Part Context

This part belongs to the LMD18200 family of H-Bridge drivers. While standard versions use plastic packaging, the /883 suffix denotes a specialized ceramic package variant intended for high-reliability sectors. It shares core electrical characteristics with commercial counterparts but adheres to stricter manufacturing controls and material specifications defined by military procurement standards.

Replacement Considerations

Direct substitutes include other radiation-hardened H-Bridge drivers from qualified manufacturers. Check pin compatibility if replacing with non-TI equivalents. Verify that alternative components meet the same -55 °C to +125 °C operating range. Ensure current handling capabilities match or exceed the 3 A requirement for safe operation.
