Substitute Part Grouping Explanation

Substitution of the LM5110-2M is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-side operation only
• Number of Drivers: Dual independent channels
• Gate Type: N-channel MOSFET driving capability
• Supply Voltage Range: 4.6V to 14V compatibility
• Logic Input Levels: VIL 0.8V, VIH 2.2V
• Peak Output Current: Source 3A minimum, Sink 5A minimum
• Input Logic: Inverting configuration
• Package: 8-SOIC form factor with 0.154" (3.90mm) width
• Mounting: Surface mount technology

The LM5110-2M/NOPB represents a direct manufacturer equivalent with identical electrical specifications and package configuration, differing only in product status classification and RoHS compliance level.

Parameter Comparison

Engineering Selection Recommendations

The LM5110-2M/NOPB is a direct functional equivalent to the LM5110-2M, with identical electrical performance and package specifications. The primary distinction lies in product lifecycle status and regulatory compliance:

• LM5110-2M: Classified as obsolete with RoHS non-compliant status. Suitable for legacy system maintenance where existing inventory is available.
• LM5110-2M/NOPB: Classified as Last Time Buy with ROHS3 compliance. Recommended for new designs and applications requiring regulatory compliance documentation.

Both parts maintain identical electrical characteristics, including supply voltage range, output current ratings, logic thresholds, and switching performance. Package compatibility is complete, enabling direct PCB-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can LM5110-2M/NOPB replace LM5110-2M in existing designs?

A: Yes. The LM5110-2M/NOPB is electrically and mechanically identical to the LM5110-2M. Pin configuration, package dimensions, and all electrical parameters are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between LM5110-2M and LM5110-2M/NOPB?

A: The primary differences are product status and RoHS compliance. LM5110-2M is obsolete and RoHS non-compliant, while LM5110-2M/NOPB is Last Time Buy and ROHS3 compliant. Electrical specifications and package form factor are identical.

Q: Are there alternative gate driver ICs with different package options?

A: The substitute list provided contains only direct manufacturer equivalents matching the specified 8-SOIC package and electrical parameters. Alternative packages or topologies would require separate evaluation against application-specific requirements.

Q: What is the significance of the /NOPB suffix?

A: The /NOPB designation indicates lead-free (Pb-free) manufacturing and RoHS3 compliance. This suffix reflects modern environmental and regulatory standards for component manufacturing.

Q: Can this part be used in high-temperature applications?

A: The LM5110-2M and LM5110-2M/NOPB are rated for operating temperatures from -40°C to 125°C (junction temperature). Applications requiring operation beyond this range require alternative components.

Q: What is the typical lead time for LM5110-2M/NOPB?

A: Lead time information is not provided in the technical specifications. Contact the supplier for current availability and delivery schedules.
