Overview
The LM5100AMR/NOPB is a high-voltage, high-side and low-side gate driver manufactured by Texas Instruments. It features independent high-side and low-side outputs capable of driving power switches with peak currents up to 3A for the A-variant. The device operates from a supply voltage range of 4.5V to 28V. It includes built-in dead-time control to prevent shoot-through currents in half-bridge configurations. The component is housed in an 8-pin SOIC (DW) surface-mount package.
Feature Summary
- Provides independent high-side and low-side gate drive signals for power switching applications
- Integrates fixed dead-time generation to ensure safe operation in bridge topologies
- Supports high-voltage operation suitable for driving various power MOSFETs and IGBTs
Applications
- Half-bridge and full-bridge power converter circuits
- Motor driver interfaces for industrial automation
- High-frequency DC-DC converter topologies
Procurement Notes
Verify that the ordering suffix /NOPB confirms lead-free compliance and RoHS standards as per manufacturer specifications. Confirm the 'AMR' suffix corresponds to the specific 3A current rating and SOIC package variant. Ensure the source document explicitly lists this exact part number to avoid confusion with similar variants like LM5100 or LM5101 which may have different electrical characteristics.
Selection Notes
Select this component when a dedicated gate driver with integrated dead-time is required for high-voltage switching applications. The 3A peak output current capability makes it suitable for driving medium-power MOSFETs. Consider the operating temperature range and package thermal performance relative to the expected load conditions and ambient environment.
Part Context
This device belongs to the LM5100 family of high-voltage gate drivers originally developed by National Semiconductor and now produced by Texas Instruments. The family includes variants with different current ratings (1A, 2A, 3A) and package options. The LM5100AMR/NOPB represents the 3A version in a reel-packaged SOIC form factor, designed for automated assembly processes.
Replacement Considerations
Public confirmed substitutes include LM5100AMX/NOPB and LM5100AM/NOPB. These parts share identical electrical specifications and pinouts but differ in packaging format (tape-and-reel vs. tube). Verify compatibility with existing PCB footprints and reflow profiles before substitution.
