IXDN404PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDN404PI 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 a non-inverting driver with independent dual-channel configuration and is packaged in an 8-DIP through-hole format. The IXDN404PI is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXDN404PI is determined by the following critical parameters:

Primary Compatibility Criteria:

• Driven configuration: Low-side operation
• Channel type: Independent dual-channel
• Input type: Non-inverting
• Package format: 8-DIP through-hole mounting
• Gate type compatibility: IGBT and/or MOSFET support

Secondary Compatibility Criteria:

• Supply voltage range overlap with 4.5V ~ 35V
• Peak output current capability (source and sink)
• Rise and fall time performance
• Operating temperature range
• Logic voltage thresholds (VIL, VIH)

Substitute parts are grouped based on their ability to meet these criteria within the constraints of the original design specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement - Full Compatibility:

IXDN604PI is the primary substitute for IXDN404PI. Both parts share identical supply voltage range (4.5V ~ 35V), matching peak output current (4A source, 4A sink), and support IGBT with N-Channel and P-Channel MOSFET gate types. IXDN604PI is active product status with ROHS3 compliance and maintains through-hole 8-DIP packaging. The faster rise/fall time (9ns, 8ns) represents improved performance over the obsolete IXDN404PI.

Secondary Replacement - Reduced Current Capability:

IXDN602PI operates within the same supply voltage range (4.5V ~ 35V) and supports identical gate types. However, peak output current is reduced to 2A source and 2A sink, limiting applicability to lower-current gate drive applications. IXDN602PI offers faster switching performance (7.5ns, 6.5ns rise/fall time) and ROHS3 compliance.

Alternative Replacement - Voltage Range Limitation:

IR4427PBF from International Rectifier operates as a low-side gate driver with independent dual channels and non-inverting input. Supply voltage range is restricted to 6V ~ 20V, which excludes applications requiring operation below 6V or above 20V. Peak output current (2.3A source, 3.3A sink) is lower than IXDN404PI. This part is suitable only for designs operating within the 6V ~ 20V window.

Alternative Replacement - Voltage and Current Limitations:

MIC4424YN and MIC4424ZN from Microchip Technology both feature supply voltage range of 4.5V ~ 18V, restricting use in applications exceeding 18V supply. Peak output current is 3A source and sink. MIC4424ZN has reduced operating temperature range (0°C ~ 150°C) compared to MIC4424YN (-40°C ~ 150°C). Both parts are ROHS3 compliant and active products.

Compliance and Availability:

All active substitute parts carry ROHS3 compliance and REACH unaffected status. IXDN604PI and IXDN602PI maintain the widest supply voltage compatibility with the original IXDN404PI specification.

Frequently Asked Questions (FAQ)

Q: Can IXDN602PI replace IXDN404PI in all applications?

A: IXDN602PI is functionally compatible for low-side gate drive applications but with reduced peak output current (2A vs 4A). Applications requiring 4A output current capability must use IXDN604PI or equivalent higher-current alternatives.

Q: What is the primary limitation of IR4427PBF as a substitute?

A: IR4427PBF operates within a restricted supply voltage range of 6V ~ 20V. The original IXDN404PI supports 4.5V ~ 35V. IR4427PBF is unsuitable for designs requiring operation below 6V or above 20V supply voltage.

Q: Are MIC4424YN and MIC4424ZN interchangeable?

A: Both parts share identical electrical specifications and package format. The primary difference is operating temperature range: MIC4424YN operates -40°C ~ 150°C while MIC4424ZN operates 0°C ~ 150°C. Selection depends on minimum operating temperature requirements.

Q: Does package format differ among substitute parts?

A: All substitute parts maintain 8-DIP through-hole packaging (0.300", 7.62mm), ensuring direct PCB compatibility with IXDN404PI footprints.

Q: Which substitute offers the best performance improvement?

A: IXDN602PI provides the fastest switching performance with 7.5ns rise time and 6.5ns fall time. IXDN604PI matches the original 4A output current while offering improved switching speed (9ns, 8ns).

Q: Are all active substitutes RoHS compliant?

A: IXDN604PI, IXDN602PI, MIC4424YN, and MIC4424ZN are ROHS3 compliant. IR4427PBF RoHS status is not specified in available documentation.
