TC4424EMF Equivalent & Substitute Parts

Part Overview

The TC4424EMF is a low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in power management applications. This non-inverting gate driver operates across a 4.5V to 18V supply voltage range and is housed in an 8-VDFN surface mount package with exposed pad. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative equivalent parts may be required due to inventory constraints, application-specific performance requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC4424EMF is determined by the following critical parameters that must remain constant across equivalent parts:

• Driven Configuration: Low-Side only
• Channel Type: Independent channels
• Number of Drivers: 2 channels
• Gate Type: N-Channel and P-Channel MOSFET compatibility
• Supply Voltage Range: 4.5V ~ 18V (minimum requirement)
• Package Type: 8-VDFN Exposed Pad (6x5) surface mount
• Input Type: Non-Inverting
• Operating Temperature Range: -40°C ~ 150°C (TJ)
• Compliance: ROHS3 Compliant, MSL 1

The TC4424AVMF qualifies as a direct substitute because it maintains identical specifications across all critical parameters while offering enhanced electrical performance characteristics in peak output current and switching speed.

Parameter Comparison

Engineering Selection Recommendations

Both TC4424EMF and TC4424AVMF are active production parts with ROHS3 compliance and identical regulatory certifications (REACH Unaffected, ECCN EAR99). Selection between these parts should be based on application requirements:

The TC4424EMF is suitable for applications where the specified 3A peak output current and 23ns/25ns rise/fall times meet design requirements.

The TC4424AVMF provides enhanced performance with 4.5A peak output current and 12ns rise/fall times, making it applicable for designs requiring higher drive capability or faster switching transitions. Both parts maintain identical supply voltage ranges, operating temperature specifications, and package footprints, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can TC4424AVMF be used as a direct replacement for TC4424EMF?

A: Yes. Both parts share identical driven configuration (low-side), channel type (independent), number of drivers (2), gate type (N-Channel and P-Channel MOSFET), supply voltage range (4.5V ~ 18V), input type (non-inverting), operating temperature range (-40°C ~ 150°C), and package specification (8-VDFN Exposed Pad, 6x5). The TC4424AVMF offers higher peak output current (4.5A vs 3A) and faster switching times (12ns vs 23ns/25ns), making it a compatible upgrade.

Q: Are there any PCB layout considerations when substituting TC4424AVMF for TC4424EMF?

A: No layout changes are required. Both parts use identical 8-VDFN Exposed Pad packages with 6x5mm dimensions and surface mount mounting type. Existing PCB designs require no modification.

Q: What is the difference in peak output current between these parts?

A: TC4424EMF provides 3A peak output current (source and sink), while TC4424AVMF provides 4.5A peak output current (source and sink). Applications requiring higher gate drive current can utilize the TC4424AVMF without design changes.

Q: Do both parts have the same compliance certifications?

A: Yes. Both TC4424EMF and TC4424AVMF are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: What is the logic voltage threshold for both parts?

A: Both parts share identical logic voltage thresholds: VIL = 0.8V and VIH = 2.4V, ensuring compatible signal interface requirements.
