TC4428EUA Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The TC4428EUA is an active low-side gate driver IC manufactured by Microchip Technology, designed to drive N-Channel and P-Channel MOSFETs with independent channel configuration. This component operates across a 4.5V to 18V supply voltage range and delivers 1.5A peak output current for both source and sink operations. The device is classified as Active product status and is ROHS3 compliant with MSL Level 1 moisture sensitivity rating.

Substitute parts become necessary when the primary part number experiences inventory constraints, extended lead times, or when alternative packaging formats (tape & reel versus tube) are required for production workflows. The parts listed below maintain electrical and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC4428EUA is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Driven Configuration: Low-Side (all substitutes must match)
• Number of Drivers: 2 (all substitutes must match)
• Gate Type: N-Channel, P-Channel MOSFET (all substitutes must match)
• Voltage - Supply: 4.5V ~ 18V (all substitutes must match)
• Current - Peak Output: 1.5A source and sink (all substitutes must match)
• Input Type: Inverting, Non-Inverting (all substitutes must match)
• Package / Case: 8-TSSOP, 8-MSOP (all substitutes must match)
• Mounting Type: Surface Mount (all substitutes must match)

Allowable Variation Parameters:

• Rise / Fall Time: Variations within typical specifications do not affect functional substitution
• Operating Temperature Range: Extended ranges (e.g., -40°C ~ 150°C vs. -40°C ~ 85°C) are acceptable
• Moisture Sensitivity Level: MSL 1 and MSL 2 are both acceptable for standard applications
• Packaging Format: Tube and Tape & Reel formats are interchangeable for component selection

All listed substitutes meet these criteria and are classified as Active product status.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the TC4428EUA within the specified parameter tolerances. Selection between these parts should be based on the following criteria:

TC4428AEUA: Direct substitute with identical electrical specifications and tube packaging format. Differs only in MSL rating (MSL 2 versus MSL 1). Suitable for applications where moisture sensitivity constraints are not critical and standard storage conditions are maintained.

MIC4428YMM: Manufacturer-recommended substitute offering extended operating temperature range (-40°C ~ 150°C junction temperature versus -40°C ~ 85°C ambient). Provides superior thermal performance for high-temperature applications. Available in tube packaging with MSL 1 rating. Rise and fall times are within acceptable variation.

MIC4428YMM-TR: Identical electrical and thermal specifications to MIC4428YMM with tape & reel packaging format. Designated for high-volume production workflows requiring automated component handling and reel-based dispensing systems. MSL 1 rating ensures unlimited shelf life under standard storage.

All parts are Active product status and ROHS3 compliant. Selection should prioritize inventory availability, packaging format requirements, and operating temperature envelope for the target application.

Frequently Asked Questions (FAQ)

Q: Can TC4428AEUA replace TC4428EUA in all applications?

A: Yes. TC4428AEUA maintains identical electrical specifications and package format. The only difference is MSL rating (MSL 2 versus MSL 1). For standard applications with controlled storage conditions, this substitution is direct.

Q: What is the difference between MIC4428YMM and MIC4428YMM-TR?

A: Both parts have identical electrical and thermal specifications. The difference is packaging format: MIC4428YMM is supplied in tube format, while MIC4428YMM-TR is supplied in tape & reel format. Selection depends on production assembly requirements and component handling systems.

Q: Are the MIC4428 parts compatible with TC4428 designs?

A: Yes. MIC4428YMM and MIC4428YMM-TR are fully compatible substitutes. All critical electrical parameters match: 2-channel low-side configuration, 4.5V to 18V supply, 1.5A peak output current, and 8-MSOP package. The MIC4428 series offers extended operating temperature range as an additional benefit.

Q: Does rise/fall time variation affect substitution eligibility?

A: No. Rise and fall time variations between parts (19ns, 20ns, or 25ns) fall within acceptable tolerances for low-side gate driver applications and do not prevent functional substitution.

Q: What does MSL rating mean for component selection?

A: MSL (Moisture Sensitivity Level) indicates shelf life under standard storage conditions. MSL 1 provides unlimited shelf life, while MSL 2 provides 1-year shelf life. For applications with extended storage or high-humidity environments, MSL 1 parts are preferred.

Q: Can I use MIC4428YMM-TR in place of tube-packaged parts?

A: Yes, from an electrical standpoint. However, tape & reel format requires compatible automated assembly equipment. Manual assembly processes typically use tube-packaged components. Verify your production workflow compatibility before substitution.

Q: Which substitute offers the best thermal performance?

A: MIC4428YMM and MIC4428YMM-TR both support -40°C to 150°C junction temperature range, compared to -40°C to 85°C ambient for TC4428EUA and TC4428AEUA. These parts are suitable for high-temperature applications.
