Overview
The LM5104M/NOPB is a high-voltage half-bridge gate driver designed to drive both high-side and low-side N-channel MOSFETs in synchronous buck configurations. It features an adaptive delay control mechanism to optimize switching performance and minimize cross-conduction risks. The device operates with a supply voltage range up to 100 V and includes an 8-V under-voltage lockout (UVLO) threshold for reliable operation. Packaged in an 8-pin SOIC, it supports operating temperatures from -40°C to +125°C.
Feature Summary
- Adaptive delay control for optimized switching timing
- High-voltage capability for driving N-channel MOSFETs
- Integrated under-voltage lockout protection
Applications
- Synchronous buck converter designs
- High-voltage motor control systems
- Industrial power supply topologies
Procurement Notes
Verify the specific suffix 'M' indicates the SOIC-8 package variant. Confirm that 'NOPB' denotes lead-free and RoHS compliance status as per Texas Instruments documentation. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability, especially given potential availability constraints for this specific part number.
Selection Notes
Select this component when a robust solution for driving high-side and low-side N-channel MOSFETs is required in high-voltage environments. The adaptive delay feature makes it suitable for applications demanding precise timing control to reduce switching losses. Consider the 8-SOIC package for standard surface-mount assembly processes.
Part Context
This device belongs to the LM5104 family of high-voltage gate drivers from Texas Instruments. It is engineered for applications requiring efficient power conversion with minimal external component count. The integration of adaptive delay distinguishes it from basic gate drivers by providing dynamic timing adjustment capabilities.
Replacement Considerations
Check for direct pin-to-pin replacements within the same manufacturer's portfolio that offer updated lifecycle status or enhanced thermal performance. Verify compatibility with existing PCB footprints and electrical specifications before substitution.
