IXDF404PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDF404PI is a low-side gate driver IC manufactured by IXYS, designed to drive IGBT and MOSFET gates in power management applications. This 8-DIP through-hole component operates across a wide supply voltage range of 4.5V to 35V and delivers 4A peak output current on both source and sink channels. 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 IXDF404PI is determined by the following critical parameters:

Primary Compatibility Criteria:

• Driven Configuration: Low-Side (all candidates match)
• Number of Drivers: 2 independent channels (all candidates match)
• Package / Case: 8-DIP through-hole form factor (all candidates match)
• Gate Type: Support for IGBT and/or MOSFET switching (all candidates match)

Secondary Compatibility Criteria:

• Voltage - Supply range must encompass or overlap with 4.5V ~ 35V
• Current - Peak Output must meet or exceed 4A source and sink requirements
• Logic Voltage thresholds must be compatible with control circuitry
• Operating Temperature range must support application requirements

Substitute Parts Identified:

1. IXDF604PI (IXYS) – Direct IXYS family substitute with matching 4A output current and identical supply voltage range
2. IXDF602PI (IXYS) – IXYS family member with reduced 2A output current and faster switching characteristics
3. MIC4425YN (Microchip Technology) – Cross-manufacturer alternative with 3A output current and reduced supply voltage range

Parameter Comparison

Engineering Selection Recommendations

IXDF604PI is the primary substitute for IXDF404PI applications. Both parts share identical supply voltage range (4.5V ~ 35V), matching 4A peak output current specifications, and equivalent low-side gate driver functionality. IXDF604PI is currently in active production status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The reduced operating temperature range (-40°C ~ 125°C vs. -55°C ~ 150°C) must be evaluated against specific application thermal requirements.

IXDF602PI is suitable for applications where peak output current requirements do not exceed 2A. This part maintains the full supply voltage range and extended temperature range (-55°C ~ 150°C) of the original IXDF404PI. Faster switching characteristics (7.5ns/6.5ns rise/fall time) may provide performance benefits in high-frequency switching applications. ROHS3 compliance and active production status support long-term system support.

MIC4425YN provides cross-manufacturer substitution capability with 3A peak output current. The reduced supply voltage range (4.5V ~ 18V) restricts this part to applications operating below 18V. Slower switching characteristics (28ns/32ns rise/fall time) compared to the original part may impact high-frequency performance. ROHS3 compliance and active production status are confirmed. This option is applicable only when supply voltage constraints are acceptable.

Frequently Asked Questions (FAQ)

Q: Can IXDF604PI directly replace IXDF404PI in all applications?

A: IXDF604PI is functionally equivalent for applications operating within -40°C ~ 125°C temperature range. The original IXDF404PI supports extended temperature operation to -55°C and 150°C. Verify application thermal requirements before substitution.

Q: What is the key difference between IXDF602PI and IXDF604PI?

A: Peak output current differs: IXDF602PI provides 2A source/sink while IXDF604PI provides 4A source/sink. Both maintain identical supply voltage range and low-side gate driver configuration. Select based on gate drive current requirements of the target IGBT or MOSFET.

Q: Is MIC4425YN suitable for 35V supply applications?

A: No. MIC4425YN maximum supply voltage is 18V. This part is restricted to applications operating at 18V or below. IXDF604PI or IXDF602PI are required for systems requiring 35V supply voltage capability.

Q: Are all substitute parts pin-compatible with IXDF404PI?

A: All substitute parts use 8-DIP through-hole packaging with identical 0.300" (7.62mm) spacing. Physical pin compatibility is confirmed. Verify logic voltage thresholds and output current specifications match application requirements before PCB layout finalization.

Q: What compliance certifications apply to substitute parts?

A: IXDF604PI, IXDF602PI, and MIC4425YN all carry ROHS3 compliance certification. REACH compliance status is unaffected for all parts. ECCN classification is EAR99 for all candidates.
