LM5102MMX Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The LM5102MMX is a half-bridge gate driver IC manufactured by Texas Instruments, designed for driving N-channel MOSFETs in half-bridge configurations. This device operates with a supply voltage range of 9V to 14V and delivers peak output currents of 1.6A for both source and sink operations. The LM5102MMX is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. Finding suitable substitutes ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM5102MMX is determined by strict equivalence across the following electrical and mechanical parameters:

• Driven configuration (half-bridge topology)
• Number of independent drivers (2 channels)
• Gate type (N-channel MOSFET)
• Supply voltage range (9V ~ 14V)
• Peak output current capability (1.6A source and sink)
• Input logic type (non-inverting)
• Bootstrap voltage rating (118V maximum)
• Propagation delay and rise/fall time characteristics (600ns typical)
• Operating temperature range (-40°C ~ 125°C)
• Package type (10-VSSOP surface mount)

The LM5102MMX/NOPB qualifies as a direct substitute because it maintains identical electrical specifications and mechanical compatibility while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The LM5102MMX/NOPB is the direct equivalent for the obsolete LM5102MMX. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The primary distinction is product status: the LM5102MMX/NOPB maintains active production status with ROHS3 compliance, whereas the original LM5102MMX is obsolete and RoHS non-compliant. For new designs and production continuity, the LM5102MMX/NOPB is the appropriate selection. The packaging difference (Tape & Reel versus bulk) reflects standard supply chain practices and does not affect electrical performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can the LM5102MMX/NOPB be used as a direct replacement for the LM5102MMX?

A: Yes. The LM5102MMX/NOPB is electrically and mechanically identical to the LM5102MMX. All electrical parameters, including supply voltage, output current, timing characteristics, and operating temperature range, are equivalent. Pin configuration and package dimensions are identical, enabling direct substitution without circuit modification.

Q: What is the difference between the LM5102MMX and LM5102MMX/NOPB?

A: The primary differences are product status and compliance certifications. The LM5102MMX is obsolete and RoHS non-compliant, while the LM5102MMX/NOPB is active and ROHS3 compliant. The /NOPB suffix indicates lead-free plating. Packaging format also differs: the original is supplied in bulk, while the substitute is supplied in Tape & Reel format for automated assembly.

Q: Are there any circuit design considerations when switching from LM5102MMX to LM5102MMX/NOPB?

A: No circuit design changes are required. Both parts operate identically within the specified electrical parameters. PCB layout, component selection, and signal routing remain unchanged.

Q: What is the 10-VSSOP package?

A: The 10-VSSOP is a surface-mount package designation indicating a 10-pin Very Small Shrink Outline Package with 0.118" (3.00mm) width. This package is suitable for high-density PCB applications and is compatible with standard automated assembly equipment.

Q: Is the LM5102MMX/NOPB suitable for high-temperature applications?

A: Yes. The LM5102MMX/NOPB operates across the temperature range of -40°C to 125°C (junction temperature), making it suitable for industrial and automotive applications within this specification.
