TC4424VMF Equivalent & Substitute Parts

Part Overview

The TC4424VMF 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 device is currently in active production status with full 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 TC4424VMF is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side only
• Number of Drivers: 2 independent channels
• Gate Type: N-Channel and P-Channel MOSFET support
• Supply Voltage Range: 4.5V ~ 18V
• Logic Voltage Thresholds: VIL 0.8V, VIH 2.4V
• Input Type: Non-Inverting
• Package: 8-VDFN Exposed Pad (surface mount)
• Operating Temperature Range: -40°C ~ 150°C (TJ)
• Compliance: RoHS3 and REACH requirements

The TC4424AVMF qualifies as a direct substitute based on identical compliance with all mandatory parameters listed above. Performance characteristics such as peak output current and rise/fall time may vary between equivalent parts; however, these variations do not disqualify substitution when the core functional and electrical parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

Both TC4424VMF and TC4424AVMF are active production devices with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on application requirements and inventory availability.

The TC4424AVMF provides enhanced performance characteristics with higher peak output current (4.5A versus 3A) and faster switching times (12ns versus 23-25ns). These improvements make the TC4424AVMF suitable for applications requiring higher drive capability or faster gate switching transitions. The TC4424VMF remains appropriate for applications where the specified 3A output current and 23-25ns switching times meet design requirements.

Both devices maintain identical core electrical parameters, package configuration, and compliance certifications, ensuring functional interchangeability within the specified operating envelope.

Frequently Asked Questions (FAQ)

Q: Can TC4424AVMF be used as a direct replacement for TC4424VMF?

A: Yes. Both devices share identical driven configuration, channel count, gate type support, supply voltage range, logic thresholds, input type, package, and operating temperature range. The TC4424AVMF meets or exceeds all core functional requirements of the TC4424VMF.

Q: What are the differences between TC4424VMF and TC4424AVMF?

A: The primary differences are peak output current (TC4424AVMF: 4.5A versus TC4424VMF: 3A) and rise/fall time performance (TC4424AVMF: 12ns versus TC4424VMF: 23-25ns). Both parameters favor the TC4424AVMF, making it suitable for higher-performance applications.

Q: Are there any package or pinout differences?

A: No. Both devices use the identical 8-VDFN Exposed Pad surface mount package with the same pinout configuration.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both TC4424VMF and TC4424AVMF are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings.

Q: Which part should be selected for new designs?

A: Selection should be based on application performance requirements and current inventory status. The TC4424AVMF is recommended for applications requiring higher output current or faster switching performance. The TC4424VMF is suitable for applications where the specified 3A output and 23-25ns switching times are sufficient.
