LM5134AMFX/NOPB

Overview

The LM5134AMFX/NOPB is a single low-side gate driver from Texas Instruments, designed for driving power MOSFETs and GaN FETs. It features a peak output current of 7.6 A and operates within a supply voltage range of 4 V to 12.6 V. The device utilizes a WSON-6 package and supports CMOS and TTL logic inputs. Key electrical parameters include a rise time of 5.3 ns and a fall time of 4.7 ns. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides high peak source and sink current capability for fast switching applications
• Includes pilot output functionality for enhanced control and monitoring
• Compatible with standard CMOS and TTL logic input levels

Applications

• Low-side gate driving for power MOSFETs in DC-DC converters
• Gate driving for Gallium Nitride (GaN) field-effect transistors
• High-frequency power conversion circuits requiring fast switching speeds

Procurement Notes

Verify the specific suffix 'AMFX' corresponds to the intended temperature grade and packaging configuration. Confirm that the WSON-6 footprint matches the design layout. Ensure the operating supply voltage remains within the specified 4 V to 12.6 V limits during system integration.

Selection Notes

Select this component when a single-channel low-side driver with high peak current is required. Consider the WSON-6 package size constraints and thermal performance. Verify compatibility with the target logic family and ensure the application benefits from the specified rise and fall times for efficiency.

Part Context

This part belongs to the LM5134 series of gate drivers. It shares core functional characteristics with other variants like the LM5134ASDX/NOPB and LM5134BMFX/NOPB, differing primarily in package type and temperature rating. The series is optimized for compact power management designs.

Replacement Considerations

LM5134ASDX/NOPB and LM5134BMFX/NOPB are confirmed substitutes within the same product family.
