LM5100ASD/NOPB

Overview

The LM5100ASD/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates independent high-side and low-side drivers in a compact 8-pin WSON package. The device supports supply voltages up to 100 V and delivers a peak output current of 2 A for both channels. It operates within an extended temperature range from -40°C to +125°C, ensuring reliable performance in demanding power conversion applications.

Feature Summary

• Integrates independent high-side and low-side drivers with bootstrap support
• Supports high-voltage operation up to 100 V bus voltage
• Provides robust 2 A peak source and sink output current capability

Applications

• High-frequency DC-DC converters
• Synchronous rectification circuits
• Isolated power supply front-ends

Procurement Notes

Verify the specific suffix 'ASD' corresponds to the 8-pin WSON package variant when sourcing. Confirm the 'NOPB' designation indicates lead-free and RoHS compliance as per Texas Instruments standards. Ensure the ordering part number matches the exact pinout and thermal pad requirements for your PCB layout design.

Selection Notes

Select this component for designs requiring a compact solution for high-voltage half-bridge topologies. The integrated bootstrap diode simplifies circuit design compared to discrete solutions. Consider the 2 A drive strength for driving medium-power MOSFETs efficiently without external buffer stages.

Part Context

This device belongs to the LM5100 family of high-voltage gate drivers. It shares functional similarities with other variants like the LM5100BMA but differs in package type and specific electrical characteristics. The ASD suffix specifically denotes the small outline no-lead (WSON) package configuration suitable for space-constrained boards.

Replacement Considerations

LM5100BSD/NOPB offers identical functionality in a different package format.
