LM5102MMX

Overview

The LM5102MMX is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It features programmable delay for dead-time control and operates with supply voltages between 9V and 14V. The device provides peak output currents of 1.6A for both sourcing and sinking. It supports high-side bootstrap voltages up to 118V and functions within a temperature range of -40°C to 125°C. The component is housed in a 10-VSSOP package.

Feature Summary

• High-voltage half-bridge configuration supporting bootstrap operation up to 118V
• Programmable delay functionality for precise dead-time management
• Non-inverting input logic compatible with standard digital interfaces

Applications

• High-voltage motor drive systems
• Industrial power conversion circuits
• Inverter bridge topologies

Procurement Notes

Verify the specific suffix 'MMX' against the manufacturer's current datasheet to confirm availability status, as some variants may be obsolete. Ensure the ordering part number matches the required RoHS compliance level and packaging type. Cross-reference the pinout with the official documentation to prevent integration errors during PCB layout.

Selection Notes

Select this component when a robust half-bridge solution with adjustable timing is required for high-voltage applications. Consider the 1.6A peak drive capability and the 10-VSSOP form factor for space-constrained designs. Verify that the input voltage levels align with the controller logic before finalizing the design.

Part Context

This device belongs to the LM5102 family of high-voltage gate drivers from Texas Instruments. It is designed to replace older National Semiconductor parts following the company acquisition. The MMX variant specifically denotes the tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

LM5102MM/NOPB is a direct replacement offering RoHS compliance.
