LM2724AM/NOPB Equivalent & Substitute Parts

Part Overview

The LM2724AM/NOPB is a half-bridge gate driver IC manufactured by Texas Instruments, designed for synchronous N-channel MOSFET switching applications. This device operates as a non-inverting gate driver with dual-channel output capability in an 8-SOIC surface mount package.

The LM2724AM/NOPB carries an Obsolete product status. Locating equivalent or substitute components is necessary for ongoing system support, design updates, and procurement continuity when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM2724AM/NOPB is determined by the following critical parameters:

Functional Requirements:

• Driven configuration must be half-bridge
• Channel type must be synchronous
• Number of drivers must be 2
• Gate type must be N-channel MOSFET
• Input type must be non-inverting

Electrical Compatibility:

• Supply voltage range must encompass or match the original specification (4.3V ~ 6.8V)
• Peak output current (source and sink) must meet or exceed original ratings (3A source, 3.2A sink minimum)
• High side bootstrap voltage must be sufficient for the application (28V minimum)
• Rise and fall times must be compatible with system switching requirements

Physical & Environmental:

• Package must be 8-SOIC surface mount
• Operating temperature range must cover -40°C ~ 125°C
• RoHS3 compliance and MSL rating must be maintained

The LM27222M/NOPB qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The LM27222M/NOPB is a qualified substitute for the LM2724AM/NOPB based on functional and electrical equivalence. Both devices are manufactured by Texas Instruments and maintain identical package geometry, pin configuration, and core switching characteristics.

The LM27222M/NOPB offers improved electrical performance in peak sink current (4.5A versus 3.2A) and higher bootstrap voltage rating (33V versus 28V), providing enhanced capability margins for demanding applications. Supply voltage ranges are compatible, with the substitute covering the original specification window.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring equivalent environmental and regulatory standing. The LM27222M/NOPB carries Last Time Buy status, indicating limited future availability. Procurement planning should account for this status when selecting between the two devices.

Frequently Asked Questions (FAQ)

Q: Can the LM27222M/NOPB directly replace the LM2724AM/NOPB without PCB modifications?

A: Yes. Both devices use identical 8-SOIC packaging with matching pin assignments and functional configurations. No PCB layout changes are required for substitution.

Q: What are the key differences between these two gate drivers?

A: The LM27222M/NOPB provides higher peak sink current output (4.5A versus 3.2A) and increased bootstrap voltage capability (33V versus 28V). Supply voltage ranges and switching characteristics remain equivalent.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and MSL Level 1 rating. No compliance differences exist between the devices.

Q: Why is the LM2724AM/NOPB marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and removed the part from active distribution. The LM27222M/NOPB represents the current-generation equivalent for new designs and ongoing support.

Q: Should I prioritize the LM27222M/NOPB over the LM2724AM/NOPB for new designs?

A: Selection should be based on application requirements and availability. The LM27222M/NOPB offers improved electrical performance margins and represents the active product line. However, Last Time Buy status indicates limited future availability for this substitute as well.

Q: Are the rise and fall times identical between these devices?

A: Yes. Both devices specify 17ns rise time and 12ns fall time, ensuring equivalent switching speed performance in half-bridge applications.
