LM5102SD Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The LM5102SD 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 LM5102SD is currently discontinued at DiGi Electronics, making identification of suitable substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM5102SD is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-Bridge topology
• Number of Drivers: 2 independent channels
• Gate Type: N-Channel MOSFET
• Voltage - Supply: 9V ~ 14V operating range
• Logic Voltage Thresholds: VIL 0.8V, VIH 2.2V
• Current - Peak Output: 1.6A source and sink capability
• Input Type: Non-Inverting signal logic
• High Side Voltage - Max (Bootstrap): 118 V maximum
• Rise / Fall Time: 600ns typical for both edges
• Operating Temperature Range: -40°C ~ 125°C (TJ)
• Package / Case: 10-WDFN Exposed Pad
• Supplier Device Package: 10-WSON (4x4)

The LM5102SD/NOPB is identified as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format (Tape & Reel versus bulk) and compliance status.

Engineering Selection Recommendations

The LM5102SD/NOPB serves as the direct functional equivalent to the LM5102SD. Both parts maintain identical electrical and mechanical specifications across all critical parameters. Selection between these parts should be based on the following factors:

Product Status: The LM5102SD is discontinued at DiGi Electronics, while the LM5102SD/NOPB carries a Last Time Buy status. For new designs or production continuity, the LM5102SD/NOPB is the appropriate selection.

Compliance: The LM5102SD/NOPB is ROHS3 compliant, whereas the original LM5102SD is RoHS non-compliant. Applications subject to RoHS regulations require the LM5102SD/NOPB.

Packaging: The LM5102SD/NOPB is supplied in Tape & Reel format, suitable for automated assembly processes. The original LM5102SD is available in bulk packaging. Packaging selection depends on production volume and assembly methodology.

Frequently Asked Questions (FAQ)

Q: Can the LM5102SD/NOPB be used as a direct replacement for the LM5102SD?

A: Yes. The LM5102SD/NOPB is electrically and mechanically identical to the LM5102SD across all specified parameters, including supply voltage, output current, timing characteristics, and package dimensions. The primary differences are product status and RoHS compliance.

Q: What is the difference between the LM5102SD and LM5102SD/NOPB?

A: Both parts are manufactured by Texas Instruments with identical electrical specifications. The LM5102SD/NOPB includes the "/NOPB" suffix, indicating lead-free and RoHS3 compliant manufacturing. The LM5102SD/NOPB is supplied in Tape & Reel packaging, while the LM5102SD is available in bulk. The LM5102SD is discontinued, while the LM5102SD/NOPB is Last Time Buy status.

Q: Are there any pin compatibility concerns when substituting these parts?

A: No. Both parts use the 10-WSON (4x4) package with identical pinout and mechanical dimensions. PCB layout and footprint remain unchanged.

Q: Which part should be selected for new production?

A: The LM5102SD/NOPB is the appropriate selection for new production due to its Last Time Buy status and ROHS3 compliance. The original LM5102SD is discontinued and should not be specified for new designs.

Q: Does the Tape & Reel packaging affect electrical performance?

A: No. Packaging format does not affect electrical characteristics. Tape & Reel packaging is a distribution and handling format suitable for automated assembly processes.
