IXDD504SIA Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDD504SIA is a low-side gate driver IC manufactured by IXYS, designed for driving IGBT and MOSFET gates in power management applications. This component operates with a supply voltage range of 4.5V to 30V and features dual independent driver channels in an 8-SOIC surface mount package. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXDD504SIA is determined by the following critical parameters that must be maintained or exceeded:

Primary Compatibility Criteria:

• Driven configuration: Low-side operation
• Channel type: Independent dual channels
• Package: 8-SOIC form factor (0.154", 3.90mm width)
• Mounting: Surface mount
• Gate type compatibility: IGBT and MOSFET support
• Input logic: Non-inverting configuration

Electrical Performance Criteria:

• Supply voltage range must encompass or exceed 4.5V minimum
• Peak output current: 4A source and sink capability
• Logic voltage thresholds: VIL ≤ 0.8V, VIH ≥ 3V
• Rise and fall times must support system switching requirements

Identified Substitutes:

1. IXDD604SIA (IXYS) – Direct family upgrade with extended supply voltage range (4.5V ~ 35V) and active product status
2. UCC27424D (Texas Instruments) – Functionally equivalent with restricted supply voltage range (4V ~ 15V) and last-time-buy status
3. UCC27424DR (Texas Instruments) – Identical electrical specifications to UCC27424D with active product status and extended inventory availability

Parameter Comparison

Engineering Selection Recommendations

IXDD604SIA is the primary substitute for IXDD504SIA applications. Both components are from the same manufacturer family with identical electrical performance characteristics (4A output current, 9ns/8ns rise/fall times, non-inverting logic). The IXDD604SIA offers an extended supply voltage range (4.5V ~ 35V versus 4.5V ~ 30V) and maintains active product status with ROHS3 compliance. This part is recommended for new designs and ongoing production support where IXYS components are preferred.

UCC27424DR is the recommended alternative when supply voltage requirements do not exceed 15V and Texas Instruments components are acceptable. This part maintains active product status with the highest inventory availability (130,400 units) and ROHS3 compliance. The UCC27424DR exhibits slower switching characteristics (20ns/15ns rise/fall times) and different logic voltage thresholds (1V/2V), which must be verified against system timing requirements.

UCC27424D shares identical electrical specifications with UCC27424DR but carries last-time-buy status, making it unsuitable for new production designs. This part should be reserved for legacy system maintenance only.

Applications requiring IGBT gate driving capability must use IXDD604SIA, as the UCC27424 series supports MOSFET gates only.

Frequently Asked Questions (FAQ)

Q: Can IXDD604SIA directly replace IXDD504SIA in existing designs?

A: Yes. Both parts share identical electrical performance (4A output current, 9ns/8ns switching times, non-inverting logic) and package form factor (8-SOIC). The IXDD604SIA provides extended supply voltage capability (35V maximum versus 30V) and active product status. No circuit modifications are required.

Q: What are the key differences between IXDD504SIA and UCC27424DR?

A: The primary differences are supply voltage range (IXDD504SIA: 4.5V ~ 30V; UCC27424DR: 4V ~ 15V), switching speed (IXDD504SIA: 9ns/8ns; UCC27424DR: 20ns/15ns), and logic voltage thresholds (IXDD504SIA: 0.8V/3V; UCC27424DR: 1V/2V). UCC27424DR does not support IGBT gate driving. These differences must be evaluated against system requirements before substitution.

Q: Is the 8-SOIC package pinout identical across all substitute parts?

A: All substitute parts use the 8-SOIC (0.154", 3.90mm width) package. Pinout compatibility must be verified against individual device datasheets, as package form factor alone does not guarantee pin-for-pin compatibility.

Q: Why is IXDD504SIA classified as obsolete?

A: The IXDD504SIA has reached end-of-life status. The IXDD604SIA serves as the active replacement within the IXYS product family, offering improved specifications and ongoing manufacturing support.

Q: Can UCC27424D be used in new production designs?

A: No. UCC27424D carries last-time-buy status, indicating no further manufacturing. UCC27424DR (active status) should be used for new designs requiring Texas Instruments components.

Q: What supply voltage range should be used when selecting between IXDD604SIA and UCC27424DR?

A: If system supply voltage exceeds 15V, IXDD604SIA is required (4.5V ~ 35V range). If supply voltage is limited to 15V or below, UCC27424DR is acceptable. IXDD604SIA is also mandatory for IGBT applications.
