LM5110-3SD/NOPB

Overview

The LM5110-3SD/NOPB is a dual-channel low-side gate driver manufactured by Texas Instruments. It provides independent high-current drive for two external MOSFETs or IGBTs in a compact WSON-10 package. The device supports a supply voltage range of 3.5 V to 14 V and delivers peak output currents of 5 A and 3 A respectively. It features non-inverting logic inputs with fast switching characteristics, including rise and fall times of 14 ns and 12 ns. The component operates reliably within an extended temperature range from -40°C to +125°C.

Feature Summary

• Dual-channel architecture providing independent control for separate low-side switches
• High peak output current capability to ensure rapid switching transitions
• Non-inverting input configuration simplifies interface with standard logic controllers
• Integrated thermal performance supporting operation in demanding industrial environments

Applications

• Synchronous rectification in DC-DC converters

Procurement Notes

Verify the specific suffix '3SD' against the manufacturer's official datasheet to confirm the distinct current ratings for each channel. Ensure the ordering part number matches the exact package variant and tape-and-reel specifications required for automated assembly processes. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when independent dual-channel low-side driving is required with asymmetric current capabilities. The device is suitable for applications needing fast switching speeds without the complexity of high-side drivers. Evaluate the WSON-10 footprint constraints and verify that the 3.5 V to 14 V supply range aligns with the system's available power rails and logic voltage levels.

Part Context

This device belongs to the LM5110 series of compound gate drivers designed for robust power switching applications. The series offers various package options and channel configurations to suit different design constraints. The LM5110-3SD/NOPB specifically addresses needs for dual low-side control with differentiated drive strengths in a small form factor.

Replacement Considerations
