MIC4424ZWM-TR Equivalent & Substitute Parts

Part Overview

The MIC4424ZWM-TR is a 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 packaged in a 16-SOIC surface mount package and is ROHS3 compliant with active product status. Equivalent and substitute parts are identified based on matching electrical specifications, package compatibility, and functional equivalence within the low-side gate driver category.

Engineering Selection Recommendations

All three parts—MIC4424ZWM-TR, TC4424COE, and TC4424COE713—are active products from Microchip Technology with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and supply chain availability:

MIC4424ZWM-TR is supplied in Tape & Reel format with MSL rating of 2 (1 Year shelf life). This packaging is optimized for high-volume automated assembly operations.

TC4424COE is supplied in Tube packaging with MSL rating of 1 (Unlimited shelf life), providing extended storage capability and flexibility for lower-volume or manual assembly processes.

TC4424COE713 is supplied in Cut Tape & Digi-Reel format with MSL rating of 1 (Unlimited shelf life), combining the benefits of tape packaging with extended moisture protection.

The TC4424COE and TC4424COE713 variants exhibit faster rise and fall times (23ns and 25ns respectively) compared to the MIC4424ZWM-TR (28ns and 32ns), representing improved switching performance while maintaining full electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can TC4424COE be used as a direct replacement for MIC4424ZWM-TR?

A: Yes. Both parts share identical electrical specifications for supply voltage, output current, logic levels, and functional configuration. The primary difference is packaging format and moisture sensitivity rating. TC4424COE is supplied in Tube packaging versus Tape & Reel for the MIC4424ZWM-TR.

Q: What is the difference between TC4424COE and TC4424COE713?

A: Both parts are electrically identical with matching specifications. The difference is packaging: TC4424COE is supplied in Tube format, while TC4424COE713 is supplied in Cut Tape & Digi-Reel format. Both have MSL rating of 1 (Unlimited shelf life).

Q: Are there timing differences between these parts?

A: The MIC4424ZWM-TR has typical rise and fall times of 28ns and 32ns. The TC4424COE and TC4424COE713 have faster typical rise and fall times of 23ns and 25ns. These differences remain within acceptable operational parameters for low-side gate driver applications.

Q: What does MSL rating mean for these parts?

A: Moisture Sensitivity Level (MSL) indicates the maximum shelf life under specified humidity conditions. MIC4424ZWM-TR has MSL 2 (1 Year), while TC4424COE and TC4424COE713 have MSL 1 (Unlimited). Higher MSL ratings require shorter storage periods and more controlled handling.

Q: Are all three parts ROHS3 compliant?

A: Yes. MIC4424ZWM-TR, TC4424COE, and TC4424COE713 are all ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the packaging format is compatible with your assembly process. All three parts use the same 16-SOIC package footprint and can be soldered using identical reflow profiles. Packaging differences (Tape & Reel, Tube, or Cut Tape & Digi-Reel) affect supply chain logistics and handling, not PCB compatibility.
