UCC27425PE4 Equivalent & Substitute Parts

Part Overview

The UCC27425PE4 is a dual-channel 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 with a supply voltage range of 4V to 15V and delivers peak output currents of 4A (source) and 4A (sink) with rise/fall times of 20ns and 15ns respectively. The UCC27425PE4 is classified as Last Time Buy, indicating end-of-life status. Identifying equivalent substitute parts is necessary to ensure continued design flexibility and supply chain continuity for applications requiring dual-channel gate driver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCC27425PE4 is determined by the following critical parameters:

• Package Compatibility: Both parts must use 8-DIP (0.300", 7.62mm) through-hole packaging to ensure direct PCB compatibility without layout modifications.
• Driven Configuration: Low-side gate driver topology must be maintained.
• Channel Count: Dual-channel (2 drivers) configuration is required.
• Supply Voltage Range: The substitute must operate within or encompass the 4V to 15V supply range.
• Peak Output Current: The substitute must meet or exceed 4A source and sink capabilities.
• Gate Type Compatibility: Support for MOSFET gate driving is mandatory.
• Compliance Standards: RoHS3 compliance and REACH unaffected status ensure regulatory alignment.

The UCC27524P qualifies as a substitute based on these parameters, offering enhanced specifications including higher supply voltage range (4.5V ~ 18V), increased peak output current (5A, 5A), faster switching times, and extended operating temperature range, while maintaining identical package form factor and low-side gate driver configuration.

Engineering Selection Recommendations

The UCC27524P is a direct substitute for the UCC27425PE4 based on the following engineering criteria:

• Product Status Alignment: The UCC27425PE4 is Last Time Buy, making the UCC27524P (Active status) the appropriate long-term replacement for new designs and ongoing production.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring no regulatory barriers to substitution.
• Package Compatibility: Identical 8-DIP through-hole packaging enables direct PCB replacement without layout redesign.
• Performance Enhancement: The UCC27524P provides superior specifications including higher supply voltage tolerance, increased output current capability, and faster switching performance, making it suitable for applications with demanding thermal or performance requirements.
• Functional Equivalence: Both devices maintain low-side gate driver configuration with dual-channel independent operation, ensuring functional compatibility in existing circuit topologies.

Frequently Asked Questions (FAQ)

Q: Can the UCC27524P be used as a direct replacement for the UCC27425PE4 on existing PCBs?

A: Yes. Both parts use identical 8-DIP (0.300", 7.62mm) through-hole packaging, enabling direct pin-for-pin substitution without PCB modifications. No layout changes are required.

Q: What are the key differences between these two gate drivers?

A: The UCC27524P offers enhanced specifications: wider supply voltage range (4.5V ~ 18V vs. 4V ~ 15V), higher peak output current (5A vs. 4A), faster switching times (7ns/6ns vs. 20ns/15ns), and extended operating temperature range (-40°C ~ 140°C vs. -40°C ~ 105°C). The UCC27425PE4 supports both inverting and non-inverting input types, while the UCC27524P is non-inverting only.

Q: Are there any input type compatibility considerations?

A: The UCC27425PE4 provides both inverting and non-inverting input configurations. The UCC27524P operates in non-inverting mode only. If your application requires inverting input functionality, circuit modifications may be necessary, or alternative substitutes should be evaluated.

Q: Do both parts support the same gate types?

A: The UCC27425PE4 drives N-Channel and P-Channel MOSFETs. The UCC27524P drives IGBTs and N-Channel MOSFETs. For P-Channel MOSFET applications, the UCC27425PE4 specifications must be verified against your specific gate type requirements.

Q: What is the significance of the Last Time Buy status for the UCC27425PE4?

A: Last Time Buy indicates the UCC27425PE4 is at end-of-life. Texas Instruments will discontinue production, making the UCC27524P the recommended active alternative for new designs and long-term supply assurance.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the UCC27425PE4 and UCC27524P are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
