TC4422VMF Equivalent & Substitute Parts

Part Overview

The TC4422VMF is a low-side gate driver IC manufactured by Microchip Technology, designed for driving IGBT, N-Channel, and P-Channel MOSFET devices. This non-inverting single-channel driver operates within a 4.5V to 18V supply voltage range and delivers 9A peak output current (source and sink). The device is housed in an 8-VDFN surface mount package with exposed pad and maintains an active product status with full RoHS3 compliance. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application performance needs.

Key Parameters

Substitute Part Grouping Explanation

The TC4422AVMF qualifies as a direct substitute for the TC4422VMF based on the following substitution criteria:

Matching Parameters (Required for Substitution):

• Manufacturer: Microchip Technology
• Driven Configuration: Low-Side
• Channel Type: Single
• Gate Type: IGBT, N-Channel, P-Channel MOSFET
• Voltage - Supply: 4.5V ~ 18V
• Logic Voltage - VIL, VIH: 0.8V, 2.4V
• Input Type: Non-Inverting
• Operating Temperature: -40°C ~ 150°C (TJ)
• Package / Case: 8-VDFN Exposed Pad
• Mounting Type: Surface Mount
• RoHS Status: RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Variant Differences: The TC4422AVMF exhibits improved electrical performance characteristics with higher peak output current (10A source and sink versus 9A) and faster switching times (38ns rise time and 33ns fall time versus 60ns for both). These enhancements make the TC4422AVMF suitable for applications requiring faster gate drive response or higher current delivery while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TC4422VMF and TC4422AVMF maintain active product status with identical compliance certifications (RoHS3 Compliant, REACH Unaffected, MSL Level 1). The TC4422AVMF represents a performance-enhanced variant within the same product family, offering increased peak output current and reduced propagation delay. Selection between these parts should be based on application requirements for output current capacity and switching speed performance, with both parts meeting identical regulatory and environmental compliance standards.

Frequently Asked Questions (FAQ)

Q: Can TC4422AVMF be used as a direct replacement for TC4422VMF?

A: Yes. Both parts share identical supply voltage ranges (4.5V ~ 18V), logic voltage thresholds (0.8V, 2.4V), operating temperature range (-40°C ~ 150°C), package configuration (8-VDFN Exposed Pad), and compliance certifications. The TC4422AVMF provides enhanced performance with higher peak output current (10A versus 9A) and faster switching times.

Q: What are the key differences between TC4422VMF and TC4422AVMF?

A: The primary differences are peak output current specifications (9A versus 10A for source and sink) and switching time performance (60ns versus 38ns/33ns for rise and fall times). All other electrical and mechanical parameters remain identical.

Q: Are both parts compatible with the same PCB layout?

A: Yes. Both parts use the identical 8-VDFN Exposed Pad surface mount package with the same pinout and footprint requirements.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both TC4422VMF and TC4422AVMF are RoHS3 Compliant, REACH Unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: Which part should be selected for high-speed switching applications?

A: The TC4422AVMF is suitable for applications requiring faster gate drive response due to its reduced propagation delay (38ns rise time and 33ns fall time compared to 60ns for both parameters on the TC4422VMF).
