Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM5100AM/NOPB is determined by the following critical parameters:

Core Functional Requirements:

• Driven Configuration: Half-Bridge
• Channel Type: Independent
• Number of Drivers: 2
• Gate Type: N-Channel MOSFET
• Input Type: Non-Inverting
• Package / Case: 8-SOIC form factor

Electrical Compatibility Criteria:

• Supply Voltage Range: Must encompass or exceed 9V ~ 14V
• Peak Output Current: Must meet or exceed 3A (source and sink)
• High Side Bootstrap Voltage: Must support minimum 118V
• Operating Temperature Range: Must cover -40°C ~ 125°C minimum

All identified substitute parts meet these core requirements. Variations in rise/fall time, logic voltage thresholds, and maximum operating temperature represent performance enhancements or extended specifications that do not preclude substitution.

Engineering Selection Recommendations

UCC27200ADR (Texas Instruments) This part maintains Texas Instruments sourcing continuity and is classified as Active product status. It provides expanded supply voltage range (8V ~ 17V) and superior rise/fall time performance (8ns, 7ns). The UCC27200ADR is available in Tape & Reel packaging and carries ROHS3 compliance with MSL 1 rating. This option is suitable for applications requiring enhanced switching speed and extended supply voltage tolerance.

HIP2100EIBZ and HIP2100EIBZT (Renesas Electronics) These variants feature an exposed pad (8-SOIC-EP) package configuration, providing improved thermal dissipation compared to standard 8-SOIC. Both are Active status products with extended operating temperature range (-55°C ~ 150°C). The HIP2100EIBZ is supplied in Tube packaging, while HIP2100EIBZT is supplied in Tape & Reel. Both carry MSL 2 rating (1 Year). These options are appropriate for thermal-sensitive applications or those requiring extended temperature operation.

HIP2100IBZ and HIP2100IBZT (Renesas Electronics) These variants use standard 8-SOIC packaging without exposed pad and maintain MSL 1 rating (Unlimited). HIP2100IBZ is supplied in Tube packaging, while HIP2100IBZT is supplied in Cut Tape & Digi-Reel. Both are Active status products with identical electrical specifications to the exposed pad variants. These options provide cost-effective substitution with standard packaging.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original LM5100AM/NOPB.

Frequently Asked Questions (FAQ)

Q: Can the UCC27200ADR replace the LM5100AM/NOPB in all applications? A: The UCC27200ADR meets all core functional requirements and exceeds the supply voltage range specification. However, applications operating at the lower end of the original 9V ~ 14V range will function within the UCC27200ADR's expanded 8V ~ 17V specification. The significantly faster rise/fall times (8ns vs. 430ns) may require circuit validation in noise-sensitive applications.

Q: What is the difference between HIP2100 variants with and without exposed pad? A: The HIP2100EIBZ and HIP2100EIBZT include an exposed pad (8-SOIC-EP) for enhanced thermal performance. The HIP2100IBZ and HIP2100IBZT use standard 8-SOIC packaging. Electrical specifications are identical. The exposed pad variant is recommended for high-power applications or environments with elevated ambient temperatures.

Q: Are there packaging compatibility considerations when substituting? A: Yes. The LM5100AM/NOPB uses standard 8-SOIC packaging. The HIP2100EIBZ and HIP2100EIBZT use 8-SOIC-EP (with exposed pad), which requires PCB layout modifications to utilize the thermal pad. The UCC27200ADR, HIP2100IBZ, and HIP2100IBZT maintain standard 8-SOIC compatibility with existing layouts.

Q: What is the significance of MSL rating differences? A: The LM5100AM/NOPB and most substitutes carry MSL 1 (Unlimited moisture sensitivity level), allowing indefinite shelf storage without baking. The HIP2100EIBZ and HIP2100EIBZT carry MSL 2 (1 Year), requiring component baking if shelf storage exceeds one year. This affects supply chain handling and storage protocols.

Q: Which substitute offers the best thermal performance? A: The HIP2100EIBZ and HIP2100EIBZT with exposed pad (8-SOIC-EP) provide superior thermal dissipation. These variants are suitable for applications where the LM5100AM/NOPB's 3A output current approaches device limits or where ambient temperatures exceed standard operating conditions.

Q: Can I use a substitute with lower peak output current (2A vs. 3A)? A: The HIP2100 series delivers 2A peak output current compared to the LM5100AM/NOPB's 3A. Substitution is valid only if circuit design margins accommodate the reduced current specification. Applications requiring the full 3A specification should use the UCC27200ADR.
