LM5134ASD/NOPB Equivalent & Substitute Parts

Part Overview

The LM5134ASD/NOPB is a low-side gate driver IC manufactured by Texas Instruments, designed for N-Channel MOSFET switching applications in power management circuits. This single-channel inverting and non-inverting gate driver operates across a 4V to 12.6V supply range and delivers peak output currents of 4.5A (source) and 7.6A (sink). The device is housed in a 6-WSON (3x3) package with exposed pad and maintains active product status with full RoHS3 compliance. Substitute parts are identified for applications requiring equivalent gate driving functionality with compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LM5134ASD/NOPB are qualified based on the following critical parameters that determine functional equivalence:

• Driven Configuration: Low-Side operation
• Channel Type: Single channel
• Gate Type: N-Channel MOSFET
• Supply Voltage Range: 4V ~ 12.6V
• Input Type: Inverting, Non-Inverting capability
• Package Type: 6-pin surface mount with exposed pad (6-WDFN / 6-TDFN)
• Mounting Type: Surface Mount
• Product Status: Active
• Compliance: RoHS3 Compliant

The identified substitutes (MAX5048AATT+T and MAX5048BATT+T) meet these core requirements. Variations in peak output current, rise/fall times, and operating temperature ranges represent acceptable parameter differences within the low-side gate driver category.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full RoHS3 compliance, qualifying them for equivalent use in low-side gate driver applications. The LM5134ASD/NOPB and its substitutes share identical supply voltage ranges (4V ~ 12.6V), package footprints (6-pin surface mount with exposed pad), and input configuration flexibility (inverting and non-inverting modes).

Selection between the LM5134ASD/NOPB and MAX5048 variants depends on application-specific requirements for peak source current and switching speed. The LM5134ASD/NOPB delivers 4.5A peak source current with 3ns rise time. The MAX5048AATT+T provides 1.3A peak source current with 8ns rise time. The MAX5048BATT+T offers extended operating temperature range to 150°C with reduced switching speed (82ns rise time, 12.5ns fall time).

All parts carry unlimited moisture sensitivity (MSL 1) and are classified under identical ECCN and HTSUS codes, ensuring regulatory equivalence for procurement and logistics purposes.

Frequently Asked Questions (FAQ)

Q: Can MAX5048AATT+T or MAX5048BATT+T directly replace LM5134ASD/NOPB in existing designs?

A: Direct replacement is possible when the application does not require the LM5134ASD/NOPB's 4.5A peak source current specification. Both MAX5048 variants deliver 1.3A peak source current. Verify that your MOSFET gate charge and switching frequency requirements are compatible with the reduced source current before substitution.

Q: What is the difference between MAX5048AATT+T and MAX5048BATT+T?

A: Both parts share identical supply voltage, package, and sink current specifications. MAX5048AATT+T operates to 125°C with 8ns rise time and 3.2ns fall time. MAX5048BATT+T extends the operating temperature range to 150°C but exhibits slower switching characteristics (82ns rise time, 12.5ns fall time). Select MAX5048BATT+T for high-temperature environments; select MAX5048AATT+T for applications requiring faster switching response.

Q: Are the package footprints identical between LM5134ASD/NOPB and MAX5048 parts?

A: All three parts use 6-pin surface mount packages with exposed pads. The LM5134ASD/NOPB uses 6-WSON (3x3) packaging, while MAX5048 variants use 6-TDFN (3x3) packaging. Both package types share identical 3x3mm footprints and pin configurations, allowing direct PCB layout compatibility.

Q: Do all three parts support both inverting and non-inverting input configurations?

A: Yes. The LM5134ASD/NOPB, MAX5048AATT+T, and MAX5048BATT+T all support both inverting and non-inverting input types, providing equivalent functional flexibility for gate drive signal conditioning.

Q: What compliance certifications apply to these parts?

A: All three parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8542.39.0001. Moisture sensitivity level is 1 (unlimited) for all parts, indicating no special handling requirements during storage or assembly.
