IXDD404SI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDD404SI 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 in an 8-SOIC package. The IXDD404SI is currently 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 eligibility for the IXDD404SI is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package type: 8-SOIC form factor (0.154", 3.90mm Width)
• Driven configuration: Low-side operation
• Channel type: Independent dual-channel
• Input logic: Non-inverting
• Peak output current: 4A source and sink capability
• Gate type support: MOSFET and IGBT compatibility

Secondary Compatibility Considerations:

• Supply voltage range (minimum 4.5V required for IXDD404SI operation)
• Logic voltage thresholds (VIL, VIH)
• Operating temperature range
• Rise and fall time specifications

The substitute parts listed below meet the primary compatibility criteria and maintain functional equivalence within the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

IXDD604SI (IXYS Integrated Circuits Division)

The IXDD604SI is the primary substitute for the IXDD404SI. Both components share identical supply voltage range (4.5V ~ 35V), dual independent channels, and 4A peak output current specifications. The IXDD604SI maintains IGBT and MOSFET gate type support and is currently in active production status. The component features an exposed pad variant of the 8-SOIC package and achieves faster switching performance (9ns/8ns rise/fall time versus 16ns/13ns). The IXDD604SI is ROHS3 compliant and represents the direct evolutionary successor within the IXYS product line.

UCC27424DR (Texas Instruments)

The UCC27424DR is a functionally equivalent substitute with active product status and highest inventory availability (130,400 pcs). This component maintains the 8-SOIC package form factor, dual independent channels, 4A peak output current, and non-inverting input configuration. The UCC27424DR operates within a reduced supply voltage range (4V ~ 15V) compared to the IXDD404SI, limiting applicability to systems operating below 15V. The component is ROHS3 compliant and available in cut tape and Digi-Reel packaging formats.

UCC27424D (Texas Instruments)

The UCC27424D shares identical electrical specifications with the UCC27424DR but carries last-time-buy product status, indicating discontinued production. This variant is suitable only for legacy system maintenance where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can the IXDD604SI directly replace the IXDD404SI in existing designs?

A: The IXDD604SI is electrically compatible with the IXDD404SI for applications operating within the 4.5V ~ 35V supply range. Both components feature identical dual independent channels, 4A peak output current, and non-inverting input configuration in the same 8-SOIC package. The IXDD604SI offers improved switching performance and active product status. PCB layout compatibility requires verification due to the exposed pad variant in the IXDD604SI package.

Q: What are the limitations of using UCC27424D or UCC27424DR as substitutes?

A: The UCC27424 series operates within a reduced supply voltage range of 4V ~ 15V, compared to the IXDD404SI maximum of 35V. These components are suitable only for applications operating below 15V supply voltage. The UCC27424D carries last-time-buy status and should not be selected for new designs. The UCC27424DR is actively produced and available in high volume.

Q: Are there package compatibility concerns between substitute parts?

A: All substitute parts use the standard 8-SOIC (0.154", 3.90mm Width) package. The IXDD604SI features an exposed pad variant (8-SOIC-EP), which may require PCB layout modifications compared to the standard 8-SOIC package used in the IXDD404SI and UCC27424 series. Thermal performance may improve with the exposed pad design in high-current applications.

Q: Which substitute is recommended for new designs?

A: The IXDD604SI is recommended for new designs requiring the full 4.5V ~ 35V supply voltage range and IGBT support. The UCC27424DR is recommended for applications operating within 4V ~ 15V supply range where Texas Instruments component qualification is required. Both components are actively produced and ROHS3 compliant.

Q: How do logic voltage thresholds affect substitution decisions?

A: The IXDD404SI specifies logic thresholds of 0.8V (VIL) and 2.5V (VIH). The IXDD604SI uses 0.8V and 3V, while the UCC27424 series uses 1V and 2V. These differences affect input signal compatibility with controller outputs. Verify that existing control signal levels meet the substitute part's logic voltage requirements before implementation.
