LM25101CMYX/NOPB

Overview

The LM25101CMYX/NOPB is a half-bridge gate driver manufactured by Texas Instruments, designed for driving N-channel MOSFETs. It operates within a supply voltage range of 9 V to 18 V and supports a maximum high-side bootstrap voltage of 100 V. The device delivers a peak output current of 3 A with typical rise and fall times of 8 ns. It functions reliably across an extended junction temperature range from -40°C to +125°C. Packaged in an MSOP-PowerPad-8 surface-mount format, it features non-inverting inputs and a low operating supply current of 250 µA.

Feature Summary

• Provides high-speed switching capability with 8 ns typical rise and fall times for efficient power stage control.
• Supports high-voltage applications with a 100 V maximum high-side bootstrap rating for robust high-side drive.
• Integrates a compact 8-pin PowerPad package design to facilitate thermal management and space-constrained layouts.

Applications

• High-frequency synchronous buck converter topologies
• Isolated DC/DC converter primary side drivers
• Motor control bridge circuits

Procurement Notes

Verify the specific suffix CMYX against the official datasheet to confirm the MSOP-PowerPad-8 package variant. Ensure the ordering quantity aligns with the standard reel packaging requirements specified by the manufacturer. Confirm RoHS compliance status through the latest environmental documentation provided by Texas Instruments prior to final procurement decisions.

Selection Notes

Select this component when a 3 A peak drive current and fast switching speeds are required for high-efficiency power conversion. The 100 V high-side rating makes it suitable for medium-voltage bus applications. Consider the MSOP-PowerPad-8 package for its balance of thermal performance and small footprint compared to larger SOIC options.

Part Context

This device belongs to the LM25101 family of half-bridge gate drivers from Texas Instruments. The family includes variants with different drive currents and packages, such as the 1 A and 2 A versions. The LM25101 series is engineered for isolated and non-isolated power supplies requiring reliable high-side and low-side MOSFET control.

Replacement Considerations

LM25101AMRX/NOPB offers similar functionality but in an 8-SO-PowerPad package with identical 3 A drive current specifications.
