MIC4422CT Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The MIC4422CT is a low-side gate driver IC manufactured by Microchip Technology, designed for driving IGBT and N-Channel MOSFET gates in power management applications. The device operates with a supply voltage range of 4.5V to 18V and delivers peak output currents of 9A (source and sink). Packaged in TO-220-5, the MIC4422CT features non-inverting logic with typical rise and fall times of 20ns and 24ns respectively.

The MIC4422CT is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications currently utilizing this component.

Substitute Part Grouping Explanation

Substitution of the MIC4422CT is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side operation
• Channel Type: Single channel
• Gate Type: IGBT and N-Channel MOSFET compatibility
• Voltage - Supply: 4.5V ~ 18V range
• Logic Voltage Thresholds: VIL = 0.8V, VIH = 2.4V
• Current - Peak Output: 9A source and sink capability
• Input Type: Non-Inverting logic
• Rise / Fall Time: 20ns rise, 24ns fall (typical)
• Operating Temperature: 0°C ~ 150°C (TJ)
• Package / Case: TO-220-5 form factor
• Mounting Type: Through Hole

Only parts meeting all these specifications are considered direct substitutes. The MIC4422ZT qualifies as a direct substitute based on complete parameter alignment.

Parameter Comparison

Engineering Selection Recommendations

The MIC4422ZT is the direct substitute for the MIC4422CT. Both parts are manufactured by Microchip Technology and share identical electrical and mechanical specifications across all critical parameters.

The MIC4422ZT offers the advantage of active product status, ensuring continued availability and manufacturer support. Additionally, the MIC4422ZT carries ROHS3 compliance, whereas the MIC4422CT is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the MIC4422ZT is the appropriate selection.

Both parts maintain REACH Unaffected status and carry the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Frequently Asked Questions (FAQ)

Q: Can the MIC4422ZT directly replace the MIC4422CT in existing designs?

A: Yes. The MIC4422ZT is a direct substitute. All electrical parameters, logic thresholds, output current ratings, timing characteristics, and thermal operating ranges are identical. The TO-220-5 package and through-hole mounting are unchanged, requiring no PCB modifications.

Q: What is the primary difference between MIC4422CT and MIC4422ZT?

A: The MIC4422CT is obsolete, while the MIC4422ZT is active. The MIC4422ZT is ROHS3 compliant, whereas the MIC4422CT is RoHS non-compliant. Functionally and electrically, both parts are equivalent.

Q: Are there any compliance considerations when switching from MIC4422CT to MIC4422ZT?

A: If your application or market requires RoHS compliance, the MIC4422ZT is mandatory. Both parts maintain REACH Unaffected status, so no additional regulatory barriers exist for the substitution.

Q: Does packaging differ between these parts?

A: The MIC4422CT is supplied in standard packaging, while the MIC4422ZT is supplied in Tube packaging. Both use the TO-220-5 form factor. Tube packaging is standard for active production parts and does not affect electrical performance or PCB integration.

Q: What is the base product number for these parts?

A: Both the MIC4422CT and MIC4422ZT share the base product number MIC4422. The suffix designates packaging and compliance variations.
