LM5101CMYE/NOPB

Overview

The LM5101CMYE/NOPB is a high-voltage half-bridge gate driver designed for driving N-channel power MOSFETs and IGBTs in hard-switching applications. It operates with supply voltages up to 60V and supports bootstrap operation for high-side driving. The device features independent high-side and low-side outputs, adjustable dead-time control, and robust protection against shoot-through. It includes under-voltage lockout (UVLO) for both channels and can drive capacitive loads directly. The component is housed in an 8-pin SOIC package.

Feature Summary

• Independent high-side and low-side gate drive outputs for half-bridge configurations
• Adjustable dead-time control to prevent cross-conduction
• Integrated under-voltage lockout for reliable startup and shutdown
• Capable of driving high-side N-channel MOSFETs via bootstrap circuit

Applications

• High-frequency DC-DC converters
• Motor control systems
• Industrial power supplies
• Inverter circuits

Procurement Notes

Verify the exact suffix NOPB indicates lead-free compliance when sourcing. Confirm the package type matches your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power rail specifications before procurement.

Selection Notes

Select this component for applications requiring isolated or non-isolated half-bridge driving with adjustable timing. Consider the maximum operating frequency and load capacitance to ensure adequate drive strength. Evaluate the thermal performance within the SOIC package for your specific power dissipation needs.

Part Context

This part belongs to Texas Instruments' LM510x family of half-bridge drivers. It is engineered for medium-power switching applications where precise timing and reliability are critical. The device complements other gate drivers by offering integrated protection features and flexible configuration options.

Replacement Considerations

Check for direct pin-compatible alternatives such as the LM5101D or LM5101PW if different packaging is required. Verify that any substitute maintains the same voltage ratings and output current capabilities. Ensure compatibility with existing control logic levels.
