UCC27425P Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The UCC27425P 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 8-PDIP through-hole component operates across a 4V to 15V supply range with dual independent channels supporting both inverting and non-inverting input configurations.

The UCC27425P carries a Last Time Buy product status, indicating it has been discontinued or is approaching end-of-life. This necessitates identifying functionally equivalent substitute components that maintain compatibility with existing designs while ensuring continued supply availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCC27425P is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-DIP (0.300", 7.62mm) through-hole package to ensure direct PCB footprint compatibility without layout modifications.

Functional Configuration: Substitute parts must support low-side gate driver operation with dual independent channels capable of driving both N-Channel and P-Channel MOSFETs.

Supply Voltage Range: The substitute must operate within or encompass the 4V to 15V supply range of the original part. Substitutes with extended voltage ranges (4.5V ~ 18V) are acceptable as they maintain backward compatibility.

Output Current Capability: The substitute must deliver peak output current (source and sink) equal to or greater than the 4A specification of the UCC27425P.

Input Configuration: The substitute must support both inverting and non-inverting input types to maintain design flexibility.

Compliance Standards: All substitutes must maintain ROHS3 compliance and EAR99 export classification.

The three identified substitutes—UCC27524P, MCP14E11-E/P, and MCP14E8-E/P—meet these core substitution criteria while offering varying performance characteristics suited to different application requirements.

Parameter Comparison

Engineering Selection Recommendations

UCC27524P (Texas Instruments): This substitute offers the highest output current capability at 5A source and sink, exceeding the UCC27425P specification. The UCC27524P features faster switching times (7ns rise, 6ns fall) and an extended operating temperature range to 140°C. However, this part supports only non-inverting input configuration, which may require circuit redesign if inverting inputs are utilized in the original application. The UCC27524P maintains active product status with established supply channels.

MCP14E11-E/P (Microchip Technology): This substitute maintains full input flexibility with both inverting and non-inverting configurations, matching the UCC27425P functional capability. The MCP14E11-E/P delivers 3A output current, which is lower than the original specification but remains suitable for applications not requiring maximum drive current. This part offers the highest operating temperature range at 150°C and carries active product status. Moisture sensitivity level MSL-1 indicates standard handling requirements.

MCP14E8-E/P (Microchip Technology): This substitute provides the lowest output current at 2A source and sink, making it suitable only for applications with reduced gate drive requirements. The MCP14E8-E/P maintains dual input configuration support and offers moderate switching performance (12ns rise, 15ns fall). This part is appropriate for cost-optimized designs where full output current capability is not required. Active product status and MSL-1 rating apply.

All three substitutes maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory continuity with the original UCC27425P design.

Frequently Asked Questions (FAQ)

Q: Can the UCC27524P directly replace the UCC27425P in all applications?

A: The UCC27524P is pin-compatible and package-compatible with the UCC27425P. However, the UCC27524P supports only non-inverting input configuration, whereas the UCC27425P supports both inverting and non-inverting inputs. If your circuit uses inverting inputs, circuit modification is required. The UCC27524P's higher output current (5A vs 4A) and faster switching times (7ns vs 20ns rise time) are generally beneficial for gate drive performance.

Q: What is the difference between the Microchip MCP14E11-E/P and MCP14E8-E/P?

A: Both Microchip parts maintain identical input configuration flexibility (inverting and non-inverting) and package compatibility. The primary difference is output current capability: the MCP14E11-E/P delivers 3A source and sink current, while the MCP14E8-E/P delivers 2A. The MCP14E11-E/P also features slightly faster switching times (25ns vs 12ns/15ns). Select the MCP14E11-E/P for applications requiring higher gate drive current; select the MCP14E8-E/P for cost-optimized designs with lower current requirements.

Q: Are all substitutes available in the same 8-DIP through-hole package?

A: Yes. All three substitute parts—UCC27524P, MCP14E11-E/P, and MCP14E8-E/P—are packaged in 8-DIP (0.300", 7.62mm) through-hole format, identical to the UCC27425P. No PCB layout modifications are required for package compatibility.

Q: What is the supply voltage compatibility of these substitutes?

A: The UCC27425P operates at 4V to 15V. The UCC27524P, MCP14E11-E/P, and MCP14E8-E/P all operate at 4.5V to 18V, which encompasses the original voltage range. All three substitutes are compatible with the UCC27425P supply voltage specification.

Q: Do all substitutes maintain the same RoHS and export compliance as the UCC27425P?

A: Yes. All three substitutes carry ROHS3 compliance and EAR99 export classification, matching the UCC27425P regulatory status. The Microchip parts carry MSL-1 moisture sensitivity rating, indicating standard handling and storage requirements.

Q: Which substitute should I select for a new design?

A: For new designs, select based on functional requirements: if inverting input capability is required, choose either MCP14E11-E/P or MCP14E8-E/P. If only non-inverting input is needed and maximum performance is desired, select UCC27524P. For applications requiring 3A or higher output current with input flexibility, MCP14E11-E/P is the preferred choice. All three carry active product status, ensuring long-term supply availability.
