TC4428VPA Equivalent & Substitute Parts

Part Overview

The TC4428VPA 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 component operates across a 4.5V to 18V supply voltage range with inverting and non-inverting input types, making it suitable for power management applications requiring precise gate control. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified based on matching electrical specifications, package compatibility, and operational parameters to ensure direct functional replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TC4428VPA are identified based on the following critical parameters that determine functional equivalence:

Core Matching Criteria:

• Driven Configuration: Low-Side
• Number of Drivers: 2 (Independent channels)
• Gate Type: N-Channel, P-Channel MOSFET support
• Supply Voltage Range: 4.5V ~ 18V
• Logic Voltage Levels: VIL 0.8V, VIH 2.4V
• Input Type: Inverting, Non-Inverting capability
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

All identified substitutes maintain these core parameters. Variations in peak output current, rise/fall time, and operating temperature range are secondary parameters that may affect performance characteristics but do not prevent functional substitution when circuit requirements permit.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts—MIC4428ZN, MIC4428YN, and MIC4425YN—maintain active production status with full RoHS3 compliance and REACH unaffected certification, matching the regulatory and compliance profile of the TC4428VPA.

MIC4428ZN and MIC4428YN provide direct electrical equivalence to the TC4428VPA with identical peak output current specifications (1.5A source/sink). The primary distinction is operating temperature range: MIC4428ZN operates from 0°C to 150°C, while MIC4428YN extends to -40°C, matching the TC4428VPA's lower temperature limit. Selection between these variants depends on application temperature requirements.

MIC4425YN offers enhanced peak output current capability (3A source/sink) while maintaining all other core electrical parameters. This part is suitable for applications requiring higher gate drive current capacity within the same package and supply voltage specifications.

All substitutes are packaged in 8-DIP through-hole format with identical pinout compatibility, enabling direct board-level replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can MIC4428ZN replace TC4428VPA in all applications? A: MIC4428ZN is electrically equivalent with matching peak output current (1.5A). The operating temperature range differs: MIC4428ZN operates from 0°C to 150°C versus TC4428VPA's -40°C to 125°C. Substitution is valid for applications within the 0°C to 125°C overlap range.

Q: What is the difference between MIC4428YN and MIC4428ZN? A: Both parts have identical electrical specifications and peak output current (1.5A). MIC4428YN supports -40°C to 150°C operating temperature, while MIC4428ZN operates from 0°C to 150°C. Selection depends on minimum operating temperature requirements.

Q: Is MIC4425YN a direct replacement for TC4428VPA? A: MIC4425YN is functionally compatible with higher peak output current (3A versus 1.5A). All core parameters—supply voltage, logic levels, input types, package, and mounting—are identical. The increased current capability makes it suitable for applications requiring higher gate drive strength.

Q: Are all substitutes available in the same package? A: Yes. TC4428VPA and all substitute parts use 8-DIP (0.300", 7.62mm) through-hole packaging with identical pinout, enabling direct board-level replacement.

Q: Do all parts meet the same compliance standards? A: Yes. TC4428VPA, MIC4428ZN, MIC4428YN, and MIC4425YN are all ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification with identical moisture sensitivity rating (MSL 1 - Unlimited).

Q: What determines whether a substitute is acceptable for my circuit? A: Core substitution criteria are driven configuration (low-side), channel count (2), gate type (N/P-Channel MOSFET), supply voltage range (4.5V-18V), logic levels (0.8V/2.4V), and package format (8-DIP). Secondary parameters such as peak output current and operating temperature must be evaluated against specific application requirements.
