LM5100CSD/NOPB

Overview

The LM5100CSD/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates independent high-side and low-side drivers capable of sourcing and sinking 2A peak currents. The device operates within a supply voltage range of 9V to 14V and supports bootstrap operation for the high-side driver. It features fast switching characteristics with typical rise and fall times of 570ns and 430ns, respectively. The component is housed in an 8-pin SOIC package and is rated for an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates independent high-side and low-side gate drivers for half-bridge configurations
• Provides 2A peak source and sink current capability for rapid MOSFET switching
• Supports bootstrap operation for floating high-side drive applications
• Features non-inverting logic inputs for straightforward control interface

Applications

• High-frequency DC-DC converter topologies
• Synchronous rectification circuits
• Motor drive systems requiring half-bridge control
• Isolated power supply gate driving stages

Procurement Notes

Verify the specific suffix 'CSD' against the official Texas Instruments datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the ordering part number matches the required temperature grade and packaging format for your production line. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and any recent pinout or electrical parameter updates before finalizing procurement.

Selection Notes

Select this component when a robust 2A drive current is required for medium-power half-bridge applications. The 9V to 14V supply range aligns with standard 12V systems. Consider the 8-pin SOIC package for through-hole or surface-mount assembly needs. Evaluate the propagation delay and switching speeds against the target switching frequency requirements to ensure minimal cross-conduction risks in the bridge circuit.

Part Context

This device belongs to the LM5100B family of high-voltage gate drivers from Texas Instruments. It shares functional similarities with other members like the LM5100BSD but differs in package configuration. The LM5100 series is designed for driving N-channel power MOSFETs in high-voltage environments, offering integrated protection features and reliable performance for industrial and automotive power electronics applications.

Replacement Considerations

Direct substitutes include LM5100BSD/NOPB and LM5100BMAX/NOPB, which share identical electrical characteristics but differ in package style (WSON vs. SOIC). Verify pin compatibility and thermal performance when swapping between different package types within the same family.
