LM5107MA Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The LM5107MA is a half-bridge gate driver IC manufactured by Texas Instruments, designed for driving N-channel MOSFETs in half-bridge configurations. This device operates as a non-inverting gate driver with independent channel control and is housed in an 8-SOIC surface mount package.

The LM5107MA carries an Obsolete part status, making it necessary to identify equivalent and substitute components for new designs and ongoing production requirements. The primary substitute maintains functional compatibility while offering improved compliance status and availability through Last Time Buy channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM5107MA is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Driven configuration (Half-Bridge)
• Number of independent drivers (2)
• Gate type (N-Channel MOSFET)
• Input logic type (Non-Inverting)

Electrical Parameters:

• Supply voltage range (8V ~ 14V)
• Logic input thresholds (VIL 0.8V, VIH 2.2V)
• Peak output current specifications (Source 1.3A, Sink 1.4A)
• Bootstrap voltage capability (118V maximum)
• Switching speed (Rise/Fall time 15ns typical)
• Operating temperature range (-40°C ~ 125°C)

Physical Parameters:

• Package type (8-SOIC)
• Package dimensions (0.154" width, 3.90mm)
• Surface mount configuration

The LM5107MA/NOPB represents a direct functional equivalent with identical electrical and mechanical specifications. This substitute maintains full compatibility with existing circuit designs while offering improved regulatory compliance status.

Engineering Selection Recommendations

For New Designs and Production Transitions:

The LM5107MA/NOPB is the appropriate selection for applications currently using or specifying the LM5107MA. This substitute provides identical electrical performance and mechanical compatibility while offering ROHS3 compliance status. The transition from the Obsolete LM5107MA to the Last Time Buy LM5107MA/NOPB ensures regulatory alignment with current environmental standards.

Compliance Considerations:

The LM5107MA/NOPB maintains REACH Unaffected status consistent with the original part. The upgrade to ROHS3 compliance eliminates restrictions on lead content and hazardous substances, supporting long-term supply chain viability and regulatory requirements in manufacturing jurisdictions with RoHS enforcement.

Availability and Supply Chain:

Current inventory levels support both immediate requirements and transition planning. The Last Time Buy status of the LM5107MA/NOPB indicates a defined production window for procurement planning.

Frequently Asked Questions (FAQ)

Q: Can the LM5107MA/NOPB be used as a direct replacement for the LM5107MA in existing designs?

A: Yes. The LM5107MA/NOPB maintains identical electrical specifications, logic thresholds, output current ratings, and package configuration. No circuit modifications are required for substitution.

Q: What is the significance of the ROHS3 compliance difference?

A: ROHS3 compliance indicates the LM5107MA/NOPB meets current restrictions on hazardous substances, including lead content limitations. This status is required for many manufacturing and distribution channels. The original LM5107MA does not carry this certification.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 8-SOIC package with 0.154" width and 3.90mm dimensions. PCB footprints and assembly processes remain unchanged.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Supply voltage range (8V ~ 14V), logic input thresholds (0.8V / 2.2V), peak output current (1.3A source / 1.4A sink), bootstrap voltage (118V maximum), and switching speed (15ns rise/fall time) must remain constant for functional equivalence.

Q: Is the operating temperature range the same for both parts?

A: Yes. Both parts operate across the -40°C to 125°C junction temperature range, supporting identical thermal design requirements.

Q: What does "Last Time Buy" status mean for the LM5107MA/NOPB?

A: Last Time Buy indicates a defined final production window for this part number. Procurement planning should account for this status when establishing long-term supply strategies.

Q: Are there any differences in moisture sensitivity between these parts?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
