IXDI402PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDI402PI is a low-side gate driver IC manufactured by IXYS, designed for driving IGBT and MOSFET gates in power management applications. This component operates as an inverting driver with independent dual-channel configuration in an 8-DIP package. The IXDI402PI is classified as obsolete, making identification of functionally equivalent active alternatives essential for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXDI402PI 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)
• Mounting Type: Must be through-hole
• Gate Type Compatibility: Must support IGBT and/or N-Channel MOSFET
• Voltage - Supply Range: Must encompass or be compatible with 4.5V ~ 35V
• Current - Peak Output: Must meet or exceed 2A source and sink capability
• Operating Temperature Range: Must cover -55°C ~ 150°C or be suitable for intended application

The substitute parts listed below maintain functional equivalence within these parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

IXDI602PI (IXYS Integrated Circuits Division) is the primary substitute for IXDI402PI. This part maintains identical electrical specifications including supply voltage range (4.5V ~ 35V), logic thresholds (0.8V, 3V), and peak output current (2A, 2A). The IXDI602PI is active product status with ROHS3 compliance and unlimited moisture sensitivity level. Rise and fall times are marginally improved (7.5ns, 6.5ns versus 8ns, 8ns). Operating temperature range matches the original (-55°C ~ 150°C). This substitution requires no circuit modifications.

IXDI604PI (IXYS Integrated Circuits Division) is suitable when higher output current capability is required. Peak output current is doubled to 4A source and sink. Supply voltage range and logic thresholds remain identical. Operating temperature range is reduced to -40°C ~ 125°C. This part is active with ROHS3 compliance. Selection of IXDI604PI is appropriate for applications requiring enhanced drive capability without circuit redesign.

IR4426PBF (International Rectifier) provides functional equivalence with active product status. Supply voltage range is narrower (6V ~ 20V) compared to the original specification. Peak output current is slightly higher (2.3A source, 3.3A sink). Logic thresholds are reduced (0.8V, 2.7V). Rise and fall times are slower (15ns, 10ns). This substitution is suitable for applications operating within the 6V ~ 20V supply range.

MIC4426YN (Microchip Technology) is the least preferred substitute due to reduced peak output current (1.5A, 1.5A) and significantly slower switching times (20ns, 29ns). Supply voltage range is limited to 4.5V ~ 18V. This part is appropriate only when output current requirements are lower than the original specification and switching speed is not critical.

Frequently Asked Questions (FAQ)

Q: Can IXDI602PI directly replace IXDI402PI without PCB modifications?

A: Yes. The IXDI602PI maintains identical electrical specifications and package configuration. No circuit modifications are required for direct substitution.

Q: What is the key difference between IXDI602PI and IXDI604PI?

A: The IXDI604PI provides doubled peak output current (4A versus 2A) and operates at a reduced maximum junction temperature (-40°C ~ 125°C versus -55°C ~ 150°C). Selection depends on application current requirements and operating temperature range.

Q: Is IR4426PBF suitable for applications requiring the full 4.5V ~ 35V supply range?

A: No. The IR4426PBF supply voltage range is limited to 6V ~ 20V. Applications requiring operation below 6V or above 20V must use IXDI602PI or IXDI604PI.

Q: Why is MIC4426YN listed as a substitute if it has lower output current?

A: MIC4426YN maintains the required low-side, dual-channel, inverting configuration in an 8-DIP package. It is suitable for applications where peak output current requirements are 1.5A or lower and switching speed is not performance-critical.

Q: Are all substitute parts available in the same 8-DIP package?

A: Yes. All substitute parts use the 8-DIP (0.300", 7.62mm) through-hole package, ensuring mechanical compatibility with existing PCB layouts.

Q: Which substitute offers the best compliance profile?

A: IXDI602PI, IXDI604PI, and MIC4426YN all carry ROHS3 compliance certification. All parts maintain REACH Unaffected status and unlimited moisture sensitivity level (MSL 1).
