LM25101AMX/NOPB

Overview

The LM25101AMX/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It integrates independent high-side and low-side drivers designed to drive N-channel power MOSFETs in hard-switching applications. The device operates within a supply voltage range of 9 V to 18 V and supports bootstrap voltages up to 100 V. It delivers peak output currents of 3 A for both sourcing and sinking, ensuring robust switching performance. Typical rise and fall times are specified at 8 ns, facilitating efficient operation in high-frequency environments.

Feature Summary

Applications

• Hard-switching power conversion circuits
• High-side and low-side MOSFET control in DC/DC converters
• Industrial motor drive systems requiring precise gate control
• Automotive power electronics applications

Procurement Notes

Verify the specific suffix 'AMX' indicates the reel packaging variant when ordering. Confirm that the component meets RoHS compliance standards as indicated by the 'NOPB' designation. Ensure the selected distributor provides traceability documentation consistent with Texas Instruments manufacturing records. Cross-reference the full part number against official TI catalogs to distinguish between tape-and-reel and tube packaging options before finalizing procurement.

Selection Notes

Select this component for applications requiring high-voltage isolation and fast switching speeds. The 3 A output current capability suits medium-power MOSFETs without external buffering. Consider the 9 V to 18 V supply range compatibility with standard logic levels. Evaluate thermal management requirements based on the SOIC-8 package limitations. Verify that the 100 V bootstrap rating aligns with the target circuit's maximum bus voltage.

Part Context

This device belongs to the LM25101 family of high-voltage gate drivers from Texas Instruments. It is specifically engineered for demanding power management tasks where reliability and speed are critical. The AMX variant denotes a specific packaging configuration optimized for automated surface-mount assembly processes. It complements other PMIC solutions by providing dedicated gate drive functionality rather than integrated power stages.

Replacement Considerations

Direct substitutes include the LM25101AM/NOPB (tube package) and LM25101AMRX/NOPB (reel package). These variants share identical electrical specifications and pinouts. Verify package type requirements before substitution to ensure compatibility with existing PCB footprints and assembly equipment.
