IXDE504PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDE504PI is a low-side gate driver IC manufactured by IXYS, designed for driving IGBT and MOSFET gates in power management applications. This inverting gate driver operates across a supply voltage range of 4.5V to 30V and delivers peak output currents of 4A for both source and sink configurations. The device is packaged in an 8-DIP through-hole format with a 0.300" (7.62mm) pitch.

The IXDE504PI is classified as obsolete, making equivalent substitute parts necessary for new designs, production continuity, and system maintenance. Identifying compatible alternatives ensures design flexibility while maintaining functional and electrical compatibility with existing circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the IXDE504PI is determined by the following critical parameters:

• Driven Configuration: Must be Low-Side
• Channel Type: Must be Independent
• Number of Drivers: Must be 2
• Input Type: Must be Inverting
• Package / Case: Must be 8-DIP (0.300", 7.62mm) through-hole
• Peak Output Current: Must support minimum 4A source and sink capability
• Gate Type Compatibility: Must support N-Channel and P-Channel MOSFET switching (IGBT support is optional)

The UCC27423P from Texas Instruments meets these core substitution criteria, providing functional equivalence within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The UCC27423P is a functional substitute for the IXDE504PI based on the following factors:

Compatibility Strengths:

• Identical low-side gate driver configuration with independent dual-channel architecture
• Matching 8-DIP through-hole package format enabling direct PCB compatibility
• Equivalent peak output current ratings (4A source and sink) for MOSFET gate drive applications
• Active product status with established supply chain availability (5022 units in stock)
• ROHS3 compliance and REACH unaffected status for regulatory alignment

Design Considerations:

• Supply voltage range is narrower (4V ~ 15V vs. 4.5V ~ 30V). Applications requiring operation above 15V require circuit redesign or alternative selection.
• Operating temperature range is reduced (-40°C ~ 125°C vs. -55°C ~ 150°C). High-temperature applications exceeding 125°C require alternative evaluation.
• Rise and fall times are slower (20ns/15ns vs. 9ns/8ns). High-frequency switching applications may require performance validation.
• IGBT gate drive capability is not specified for the UCC27423P. IGBT-specific applications require confirmation of compatibility or alternative selection.
• Logic input thresholds differ (VIL/VIH: 1V/2V vs. 0.8V/3V). Signal conditioning may be required for marginal input voltage levels.

Frequently Asked Questions (FAQ)

Q: Can the UCC27423P directly replace the IXDE504PI on existing PCBs?

A: Yes, for applications within the UCC27423P operating specifications. Both devices use identical 8-DIP through-hole packaging with 0.300" (7.62mm) pitch, enabling direct socket compatibility. Verify that your circuit operates within the UCC27423P supply voltage range (4V ~ 15V) and temperature range (-40°C ~ 125°C).

Q: What are the key electrical differences between these parts?

A: The primary differences are supply voltage range (IXDE504PI: 4.5V ~ 30V; UCC27423P: 4V ~ 15V), operating temperature range (IXDE504PI: -55°C ~ 150°C; UCC27423P: -40°C ~ 125°C), and switching speed (IXDE504PI: 9ns/8ns rise/fall; UCC27423P: 20ns/15ns rise/fall). Both deliver identical 4A peak output current and support independent dual-channel inverting gate drive.

Q: Is the UCC27423P suitable for IGBT applications?

A: The UCC27423P gate type specification lists N-Channel and P-Channel MOSFET support only. IGBT gate drive capability is not documented. If IGBT switching is required, confirm compatibility with Texas Instruments technical documentation or select an alternative part.

Q: What happens if my circuit operates above 15V supply voltage?

A: The UCC27423P maximum supply voltage is 15V. Operating above this rating violates device specifications and may cause permanent damage. For applications requiring supply voltages above 15V, the IXDE504PI or alternative high-voltage gate drivers must be selected.

Q: Are there packaging or mounting differences?

A: No. Both the IXDE504PI and UCC27423P use 8-DIP through-hole packaging with identical 0.300" (7.62mm) pitch. PCB footprints are mechanically compatible without modification.

Q: How do the logic input thresholds compare?

A: The IXDE504PI specifies VIL = 0.8V and VIH = 3V, while the UCC27423P specifies VIL = 1V and VIH = 2V. The UCC27423P has tighter input thresholds. If your control signal operates near the IXDE504PI thresholds, signal conditioning or level shifting may be required for reliable UCC27423P operation.
