MAX4427ESA-T Equivalent & Substitute Parts

Part Overview

The MAX4427ESA-T is a low-side gate driver IC manufactured by Analog Devices Inc./Maxim Integrated, designed for driving N-Channel and P-Channel MOSFETs in independent channel configurations. This non-inverting gate driver operates across a 4.5V to 18V supply voltage range with 1.5A peak output current capability. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain compatibility across electrical specifications, package form factor, and operational parameters to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4427ESA-T is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Driven Configuration: Low-Side
• Channel Type: Independent
• Number of Drivers: 2
• Gate Type: N-Channel, P-Channel MOSFET
• Input Type: Non-Inverting
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Electrical Operating Range:

• Supply voltage range must encompass or match 4.5V ~ 18V
• Logic voltage thresholds (VIL, VIH) must be compatible with 0.8V, 2.4V
• Peak output current (source and sink) must meet or exceed 1.5A, 1.5A
• Rise and fall times must support system timing requirements

Compliance Requirements:

• RoHS3 Compliant
• MSL 1 (Unlimited)

All substitute parts listed maintain these core parameters, ensuring functional equivalence and direct replacement capability in the 8-SOIC package form factor.

Parameter Comparison

Engineering Selection Recommendations

MAX4427ESA+T (Analog Devices Inc./Maxim Integrated) This part is the direct successor to the MAX4427ESA-T, maintaining identical electrical specifications and package form factor. Product status is active with 2700 units in stock. This represents the primary substitution path for obsolete MAX4427ESA-T applications. Packaging is available in Cut Tape (CT) and Digi-Reel formats.

UCC27324DR (Texas Instruments) This Texas Instruments gate driver provides enhanced performance characteristics with 4A peak output current (versus 1.5A) and extended operating temperature range (-55°C to 150°C junction temperature). Supply voltage range is 4.5V to 15V, which covers the lower operating envelope of the MAX4427ESA-T. Logic voltage thresholds differ slightly (1V, 2V versus 0.8V, 2.4V). This part is suitable for applications requiring higher output current capability or extended temperature operation. Inventory availability is 105,100 units.

MIC4427YM (Microchip Technology) This Microchip gate driver maintains electrical compatibility with the MAX4427ESA-T across supply voltage (4.5V ~ 18V) and logic thresholds (0.8V, 2.4V). Operating temperature range extends to 150°C junction temperature. Rise and fall times are 20ns and 29ns respectively. Packaging is supplied in tube format with 17,581 units in stock.

MIC4427YM-TR (Microchip Technology) This variant is identical to MIC4427YM in electrical specifications but supplied in Cut Tape (CT) and Digi-Reel packaging format. Inventory availability is 1,818 units. This option provides the same functional compatibility as MIC4427YM with alternative packaging.

Frequently Asked Questions (FAQ)

Q: Can MAX4427ESA+T be used as a direct replacement for MAX4427ESA-T? A: Yes. MAX4427ESA+T maintains identical electrical specifications, logic thresholds, output current ratings, and 8-SOIC package form factor. The primary difference is product status (active versus obsolete) and packaging format availability.

Q: What are the key differences between UCC27324DR and MAX4427ESA-T? A: UCC27324DR provides 4A peak output current compared to 1.5A in the MAX4427ESA-T, and supports extended operating temperature to 150°C. Supply voltage range is 4.5V to 15V (versus 4.5V to 18V). Logic voltage thresholds are 1V and 2V (versus 0.8V and 2.4V). These differences must be evaluated against specific application requirements.

Q: Are Microchip MIC4427YM and MIC4427YM-TR electrically identical? A: Yes. Both parts are electrically identical with matching specifications. The difference is packaging format: MIC4427YM is supplied in tube packaging, while MIC4427YM-TR is supplied in Cut Tape (CT) and Digi-Reel format.

Q: Do all substitute parts maintain the same 8-SOIC package dimensions? A: Yes. All listed substitute parts use the 8-SOIC package with 0.154" (3.90mm) width, ensuring PCB layout compatibility without redesign.

Q: Which substitute part offers the best thermal performance? A: UCC27324DR, MIC4427YM, and MIC4427YM-TR all support operating temperatures to 150°C (junction temperature), compared to 85°C (ambient temperature) for MAX4427ESA-T. UCC27324DR additionally provides the highest peak output current at 4A.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original MAX4427ESA-T specifications.
