LM5110-3MX Equivalent & Substitute Parts

Part Overview

The LM5110-3MX is a low-side gate driver IC manufactured by Texas Instruments, designed for driving N-Channel MOSFETs in power management applications. This device features independent dual-channel configuration with inverting and non-inverting input types, operating across a 4.6V to 14V supply voltage range. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM5110-3MX is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side operation only
• Channel Architecture: Independent dual-channel configuration
• Gate Type: N-Channel MOSFET driver capability
• Supply Voltage Range: 4.6V ~ 14V
• Peak Output Current: 3A source, 5A sink
• Input Configuration: Inverting and Non-Inverting channels
• Switching Performance: Rise/Fall times of 14ns and 12ns respectively
• Package Form Factor: 8-SOIC surface mount package
• Temperature Range: -40°C to 125°C junction temperature

The LM5110-3MX/NOPB qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all listed parameters.

Parameter Comparison

Engineering Selection Recommendations

The LM5110-3MX/NOPB serves as the direct substitute for the obsolete LM5110-3MX. Both parts maintain identical electrical and mechanical specifications across all functional parameters. The primary distinction lies in product status and regulatory compliance: the LM5110-3MX/NOPB is classified as active and carries ROHS3 compliance certification, whereas the original part is obsolete and RoHS non-compliant.

For new designs or production transitions, the LM5110-3MX/NOPB is the appropriate selection. The /NOPB designation indicates lead-free, halogen-free packaging in compliance with modern environmental standards. Existing designs using the LM5110-3MX can transition to the LM5110-3MX/NOPB without circuit modification, as all functional parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the LM5110-3MX/NOPB be used as a direct replacement for the LM5110-3MX?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including supply voltage range, output current ratings, switching times, and package form factor. The primary difference is product status and compliance certification.

Q: What does the /NOPB suffix indicate?

A: The /NOPB designation specifies lead-free and halogen-free packaging, meeting ROHS3 compliance requirements. This is a packaging and environmental compliance designation, not a functional modification.

Q: Are there any circuit design changes required when switching from LM5110-3MX to LM5110-3MX/NOPB?

A: No circuit modifications are necessary. The electrical specifications, pin configuration, and functional behavior are identical between the two parts.

Q: What is the significance of the obsolete status for the LM5110-3MX?

A: Obsolete status indicates the part is no longer manufactured or supported by Texas Instruments. The LM5110-3MX/NOPB is the active equivalent and should be used for all new designs and production requirements.

Q: Are both parts available in the same packaging options?

A: Both parts are supplied in 8-SOIC surface mount packages. The LM5110-3MX/NOPB is available in Cut Tape (CT) and Digi-Reel packaging options, as well as Tape & Reel (TR) format.
