IXDI502PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDI502PI is a low-side gate driver IC manufactured by IXYS, designed for driving IGBT and MOSFET gates in power management applications. This 8-DIP through-hole component operates across a 4.5V to 30V supply range with independent dual-channel configuration and inverting input logic. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IXDI502PI is determined by the following critical parameters:

• Driven Configuration: Must be low-side
• Channel Type: Must be independent dual-channel
• Number of Drivers: Must be 2
• Input Type: Must be inverting
• Package / Case: Must be 8-DIP (0.300", 7.62mm) through-hole
• Gate Type Compatibility: Must support IGBT and/or N-Channel MOSFET operation
• Voltage - Supply Range: Must encompass or overlap the 4.5V minimum requirement
• Current - Peak Output: Must meet or exceed 2A source and sink capability
• Operating Temperature Range: Must support -55°C to 150°C or equivalent industrial range

The three substitute parts listed below meet these core substitution criteria with varying degrees of parameter alignment.

Engineering Selection Recommendations

IXDI602PI is the primary substitute for IXDI502PI. Both parts are manufactured by IXYS with identical electrical characteristics (2A source/sink current, 7.5ns/6.5ns rise/fall times) and matching operating temperature range (-55°C to 150°C). The IXDI602PI offers an extended supply voltage range (4.5V to 35V versus 4.5V to 30V) and maintains full gate type compatibility including IGBT support. The part is currently active with ROHS3 compliance and unlimited moisture sensitivity rating. Direct pin-compatible replacement with no design modifications required.

IR4426PBF is a secondary substitute suitable for applications where supply voltage does not exceed 20V. This International Rectifier part provides higher peak output current (2.3A source, 3.3A sink) and maintains IGBT compatibility. However, the reduced supply voltage range (6V to 20V) and slower switching characteristics (15ns/10ns rise/fall times) limit its applicability to lower-voltage system designs. Operating temperature range extends to -40°C, which may be insufficient for extreme cold environments.

TC1426CPA from Microchip Technology is a tertiary option with significant limitations. The reduced peak output current (1.2A source/sink) and narrower supply voltage range (4.5V to 16V) restrict its use to lower-power applications. The operating temperature range (0°C to 70°C) is substantially narrower than the original part, making it unsuitable for industrial or extended-temperature applications. Slower switching characteristics (35ns/25ns rise/fall times) may impact system performance in high-frequency switching circuits. IGBT support is not specified.

Frequently Asked Questions (FAQ)

Q: Can IXDI602PI be used as a direct replacement for IXDI502PI?

A: Yes. The IXDI602PI is pin-compatible and electrically equivalent to the IXDI502PI. Both parts share identical dual-channel low-side gate driver architecture, 2A peak output current, and -55°C to 150°C operating temperature range. No circuit modifications are required for substitution.

Q: What is the key difference between IXDI502PI and IXDI602PI?

A: The primary difference is supply voltage range. IXDI602PI extends the maximum supply voltage to 35V compared to 30V for IXDI502PI. All other electrical parameters remain identical. IXDI602PI is also currently in active production status.

Q: Is IR4426PBF suitable for all IXDI502PI applications?

A: IR4426PBF is suitable only for applications where the supply voltage does not exceed 20V. The part provides higher peak output current but exhibits slower switching times (15ns/10ns versus 7.5ns/6.5ns). Applications requiring operation above 20V or demanding fast switching response should use IXDI602PI instead.

Q: Why is TC1426CPA not recommended as a primary substitute?

A: TC1426CPA has three significant limitations: reduced peak output current (1.2A versus 2A), narrower supply voltage range (4.5V to 16V), and restricted operating temperature range (0°C to 70°C). These constraints make it unsuitable for industrial applications or systems requiring the full temperature performance of the original IXDI502PI. IGBT support is also not specified.

Q: Are all substitute parts available in 8-DIP through-hole packaging?

A: Yes. All three substitute parts (IR4426PBF, IXDI602PI, TC1426CPA) are available in 8-DIP (0.300", 7.62mm) through-hole packaging, ensuring mechanical compatibility with existing PCB layouts.

Q: What compliance certifications apply to these substitute parts?

A: IXDI602PI and TC1426CPA are ROHS3 compliant. All parts carry EAR99 export classification and are REACH unaffected. Moisture sensitivity level is rated as 1 (unlimited) for IXDI602PI and TC1426CPA.
