LM5101AMR/NOPB

Overview

The LM5101AMR/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates independent high-side and low-side drivers in an 8-pin SOIC package. The device supports supply voltages from 9V to 14V and delivers peak output currents of 3A for both channels. It features non-inverting logic inputs, propagation delays up to 26ns, and operates within a junction temperature range of -40°C to +125°C.

Feature Summary

• Integrates independent high-side and low-side gate drivers for half-bridge configurations
• Provides robust 3A peak source and sink current capability for fast switching
• Supports non-inverting logic input compatibility with standard control interfaces

Applications

• High-side and low-side MOSFET driving in power conversion circuits
• Industrial motor control systems requiring isolated or floating drive signals
• Automotive power management applications utilizing half-bridge topologies

Procurement Notes

Verify the specific suffix 'MR' against official Texas Instruments documentation to confirm tape-and-reel packaging and exact electrical grade. Ensure the component matches the required SOIC-8 footprint and thermal characteristics for your design. Cross-reference the datasheet revision date to validate all performance parameters before finalizing procurement specifications.

Selection Notes

Select this component when a single IC solution is needed to drive both sides of a half-bridge with high current capability. It is suitable for designs requiring independent control of high-side and low-side switches without external bootstrap circuitry complexity. Consider the 3A output strength for driving larger MOSFETs with low gate charge requirements efficiently.
