LM25101BMAX/NOPB

Overview

The LM25101BMAX/NOPB is a half-bridge gate driver manufactured by Texas Instruments, designed for driving N-channel power MOSFETs. It features an 8-SOIC package with an operating temperature range of -40°C to +125°C. The device supports supply voltages from 9V to 14V and provides configurable peak output currents of 3A, 2A, or 1A. It includes an 8-V under-voltage lockout (UVLO) threshold and accepts TTL-compatible logic inputs.

Feature Summary

• Configurable peak output current capability supporting 3-A, 2-A, or 1-A drive levels
• Integrated 8-V under-voltage lockout (UVLO) for reliable operation monitoring
• TTL-compatible input logic for direct interface with standard digital controllers

Applications

• High-side and low-side MOSFET gate driving in power conversion circuits
• Industrial motor control systems requiring robust half-bridge drivers
• Automotive power management applications within specified voltage ranges

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm the exact electrical characteristics, particularly the configured output current rating. Ensure the package type matches the required PCB footprint and that the UVLO threshold aligns with system requirements before finalizing procurement.

Selection Notes

Select this component when a half-bridge driver with adjustable drive strength is required. The 8-SOIC package offers a compact solution for space-constrained designs. Verify compatibility with the target MOSFET gate charge requirements and ensure the supply voltage remains within the 9V to 14V operational window for optimal performance.

Part Context

This device belongs to the LM25101 family of half-bridge gate drivers from Texas Instruments. It is engineered for high-reliability applications in industrial and automotive sectors. The NOPB suffix indicates lead-free construction compliant with RoHS standards, ensuring environmental safety without compromising electrical performance or thermal stability.

Replacement Considerations

Consult official substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications carefully to ensure functional equivalence in existing designs.
