LM25101AM/NOPB Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The LM25101AM/NOPB is a half-bridge gate driver IC manufactured by Texas Instruments, designed for driving N-channel MOSFETs in half-bridge configurations. This non-inverting gate driver operates with a supply voltage range of 9V to 14V and delivers peak output currents of 3A for both source and sink operations. The device is packaged in an 8-SOIC surface mount package with a maximum bootstrap voltage rating of 100V.

The LM25101AM/NOPB is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for new production runs and long-term product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM25101AM/NOPB is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-Bridge topology with independent dual channels
• Gate Type & Input Logic: N-Channel MOSFET drivers with non-inverting input control
• Electrical Performance: Supply voltage range 9V–14V, peak output current 3A source/sink, bootstrap voltage 100V maximum
• Timing Characteristics: Rise and fall times of 430ns and 260ns respectively
• Package Compatibility: 8-SOIC surface mount package with identical 3.90mm width
• Environmental & Compliance: Operating temperature -40°C to 125°C, ROHS3 compliance, MSL Level 1

The LM25101AMX/NOPB qualifies as a direct substitute based on identical electrical specifications and package form factor. The only distinction is packaging format: the main part is supplied in Tube packaging, while the substitute is supplied in Tape & Reel format.

Parameter Comparison

Engineering Selection Recommendations

The LM25101AMX/NOPB is a direct electrical and mechanical equivalent to the LM25101AM/NOPB. Both devices share identical electrical specifications, thermal operating range, and 8-SOIC package dimensions. The primary distinction is product status and packaging format.

The LM25101AM/NOPB is designated Last Time Buy, indicating discontinued production. The LM25101AMX/NOPB maintains Active product status with higher inventory availability (5381 units versus 2700 units), ensuring sustained supply chain access for ongoing production requirements.

Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications. The Tape & Reel packaging of the LM25101AMX/NOPB is standard for high-volume manufacturing and automated assembly processes, whereas Tube packaging is typically used for lower-volume or manual assembly scenarios.

Frequently Asked Questions (FAQ)

Q: Can the LM25101AMX/NOPB be used as a direct replacement for the LM25101AM/NOPB in existing designs?

A: Yes. The LM25101AMX/NOPB is electrically and mechanically identical to the LM25101AM/NOPB. All electrical parameters, timing characteristics, and package dimensions are equivalent. No circuit modifications or PCB layout changes are required.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging contains individual components in a plastic tube, suitable for manual handling and lower-volume assembly. Tape & Reel packaging presents components on a continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly equipment. Both formats contain identical components with identical electrical performance.

Q: Why is the LM25101AM/NOPB marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. Existing inventory is available for purchase, but no new production runs will occur. The LM25101AMX/NOPB remains in Active production status and is the recommended part for new designs and ongoing supply requirements.

Q: Are there any thermal or reliability differences between these two part numbers?

A: No. Both parts operate across the identical temperature range (-40°C to 125°C junction temperature) and carry the same Moisture Sensitivity Level (MSL 1). Reliability and thermal performance are equivalent.

Q: What are the key parameters that define substitution eligibility for this gate driver?

A: Substitution is determined by matching: half-bridge topology, dual independent N-channel MOSFET drivers, non-inverting input logic, 9V–14V supply voltage, 3A peak output current (source and sink), 100V bootstrap voltage rating, 430ns/260ns rise/fall times, 8-SOIC package form factor, and -40°C to 125°C operating temperature range.
