TC4424EOE Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The TC4424EOE is an active low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in independent dual-channel configurations. This non-inverting gate driver operates across a 4.5V to 18V supply voltage range and delivers 3A peak output current for both source and sink operations. The device is housed in a 16-SOIC surface mount package and maintains active product status with full ROHS3 compliance and REACH unaffected certification.

Equivalent and substitute parts are necessary when the primary TC4424EOE variant becomes unavailable, when specific packaging formats are required for manufacturing processes, or when alternative temperature ratings better suit application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC4424EOE is determined by strict equivalence across the following core parameters:

Critical Matching Parameters:

• Driven Configuration: Low-Side
• Channel Type: Independent
• Number of Drivers: 2
• Gate Type: N-Channel, P-Channel MOSFET
• Voltage - Supply: 4.5V ~ 18V
• Logic Voltage - VIL, VIH: 0.8V, 2.4V
• Current - Peak Output (Source, Sink): 3A, 3A
• Input Type: Non-Inverting
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Allowable Variations:

• Rise / Fall Time (Typ): Variations within 23ns to 32ns range are acceptable
• Operating Temperature Range: Minimum temperature may vary (-40°C or 0°C); maximum remains 150°C
• Packaging Format: Tube, Cut Tape (CT), or Tape & Reel (TR)

All substitute parts listed maintain identical electrical specifications, package geometry, and compliance certifications as the TC4424EOE.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and functional equivalence to the TC4424EOE within the specified operating parameters. Selection among available substitutes should be based on the following criteria:

Packaging Format Requirements:

• MIC4424YWM (Tube packaging) is suitable for manual assembly or small-batch production workflows
• MIC4424YWM-TR (Cut Tape format) accommodates pick-and-place equipment with standard tape feeders
• MIC4424ZWM-TR (Tape & Reel format) is optimized for high-volume automated assembly lines

Temperature Range Considerations:

• TC4424EOE and MIC4424YWM/MIC4424YWM-TR support -40°C minimum operating temperature, suitable for extended temperature range applications
• MIC4424ZWM-TR operates from 0°C minimum, appropriate for standard industrial temperature environments

Compliance and Certification: All substitute parts carry identical ROHS3 compliance and REACH unaffected certification status, ensuring regulatory equivalence across all variants.

Timing Performance: Rise and fall time specifications vary slightly between the TC4424EOE (23ns/25ns) and MIC4424 variants (28ns/32ns). Both remain within acceptable operational margins for low-side gate driver applications.

Frequently Asked Questions (FAQ)

Q: Can MIC4424YWM-TR be used as a direct replacement for TC4424EOE in production assembly?

A: Yes. MIC4424YWM-TR is electrically and functionally equivalent to TC4424EOE. The primary difference is packaging format (Cut Tape versus unspecified). Both devices share identical electrical specifications, gate driver configuration, and compliance certifications. Verify that your assembly equipment supports Cut Tape format feeding.

Q: What is the difference between MIC4424YWM and MIC4424YWM-TR?

A: Both parts are electrically identical. The difference is packaging format only: MIC4424YWM is supplied in Tube format, while MIC4424YWM-TR is supplied in Cut Tape (CT) format. Select based on your manufacturing process requirements.

Q: Is MIC4424ZWM-TR suitable for applications requiring -40°C operation?

A: No. MIC4424ZWM-TR operates from 0°C minimum temperature. For applications requiring -40°C operation, use TC4424EOE, MIC4424YWM, or MIC4424YWM-TR instead.

Q: Do the timing differences between TC4424EOE and MIC4424 variants affect circuit performance?

A: The TC4424EOE specifies 23ns/25ns rise/fall times, while MIC4424 variants specify 28ns/32ns. Both remain within acceptable operational parameters for low-side gate driver applications. Verify timing margins in your specific circuit design if gate switching speed is critical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TC4424EOE and all listed substitute parts (MIC4424YWM, MIC4424YWM-TR, MIC4424ZWM-TR) are ROHS3 compliant and REACH unaffected.

Q: What does Moisture Sensitivity Level (MSL) mean for component storage?

A: MSL indicates maximum shelf life before moisture absorption requires baking. TC4424EOE carries MSL 1 (unlimited shelf life). MIC4424 variants carry MSL 2 (1 year shelf life). Store MSL 2 components in dry conditions and follow manufacturer storage guidelines.
