UCC27424P Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The UCC27424P is a low-side gate driver IC manufactured by Texas Instruments, designed for driving N-Channel and P-Channel MOSFETs in power management applications. This device operates as a non-inverting driver with independent dual channels in an 8-PDIP package. The UCC27424P is currently in Last Time Buy status, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain compatibility with the same package type, driven configuration, and core electrical characteristics to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCC27424P is determined by the following critical parameters:

• Package compatibility: 8-DIP (0.300", 7.62mm) through-hole mounting
• Driven configuration: Low-side gate driver topology
• Channel architecture: Independent dual-channel configuration
• Input logic: Non-inverting operation
• Gate compatibility: Support for N-Channel and/or P-Channel MOSFETs
• Supply voltage range: Minimum 4V operation capability
• Peak output current: Minimum 4A source and sink capability

All substitute parts listed maintain these core requirements. Variations in supply voltage upper limits, output current ratings, and operating temperature ranges represent performance enhancements or extended specifications that do not prevent functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The UCC27424P is in Last Time Buy status, requiring transition to active alternatives. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

UCC27524P represents the primary upgrade path within the Texas Instruments product line. This part offers enhanced performance with 5A peak output current, faster switching times (7ns/6ns rise/fall), and extended supply voltage range (4.5V ~ 18V). The UCC27524P also supports IGBT gate driving in addition to MOSFET applications, providing broader application flexibility.

MIC4424YN and MIC4424ZN from Microchip Technology provide 3A peak output current with identical gate type support (N-Channel, P-Channel MOSFET). The primary distinction between these variants is operating temperature range: MIC4424YN operates -40°C ~ 150°C, while MIC4424ZN operates 0°C ~ 150°C. Both feature extended supply voltage capability (4.5V ~ 18V) and are in active production status.

MIC4427YN and MIC4427ZN offer reduced peak output current (1.5A) compared to the UCC27424P. These parts are suitable for applications with lower gate drive current requirements. Like the MIC4424 variants, they differ in operating temperature range: MIC4427YN supports -40°C ~ 150°C, while MIC4427ZN supports 0°C ~ 150°C.

For applications requiring the full 4A output current specification of the UCC27424P, UCC27524P or MIC4424 variants are appropriate selections. For lower current applications, MIC4427 variants provide cost-effective alternatives. Temperature range requirements should guide selection between Y-grade (extended low-temperature) and Z-grade (standard low-temperature) variants.

Frequently Asked Questions (FAQ)

Q: Can UCC27524P directly replace UCC27424P in existing designs?

A: Yes. UCC27524P maintains identical package, pin configuration, and driven configuration. The higher 5A output current and faster switching times represent performance enhancements. Supply voltage minimum increases from 4V to 4.5V; verify your application operates within 4.5V ~ 18V range.

Q: What is the difference between MIC4424 and MIC4427 variants?

A: Both are low-side gate drivers in 8-DIP packages with identical package and configuration. The primary difference is peak output current: MIC4424 provides 3A, while MIC4427 provides 1.5A. Select based on your gate drive current requirements.

Q: Why do MIC4424 and MIC4427 parts have Y and Z grade options?

A: The Y-grade variants (MIC4424YN, MIC4427YN) operate across -40°C ~ 150°C temperature range. The Z-grade variants (MIC4424ZN, MIC4427ZN) operate across 0°C ~ 150°C. Select Y-grade for applications requiring full extended low-temperature operation; select Z-grade for standard industrial temperature ranges.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original UCC27424P.

Q: Can MIC4427 parts substitute for UCC27424P if my application requires only 1.5A output current?

A: Yes, if your gate drive current requirement is 1.5A or less. MIC4427 variants maintain identical package, configuration, and non-inverting input type. Verify operating temperature requirements align with either Y-grade (-40°C ~ 150°C) or Z-grade (0°C ~ 150°C) specifications.

Q: What is the minimum supply voltage for each substitute part?

A: UCC27424P operates 4V ~ 15V. All substitute parts operate 4.5V ~ 18V minimum. If your application operates below 4.5V, UCC27424P or UCC27524P must be verified for compatibility at your specific voltage.

Q: Are there pin-to-pin compatibility differences between these parts?

A: All parts use identical 8-DIP package and maintain low-side gate driver configuration. Pin assignments are compatible for direct substitution within the same package type.
