IXDI504PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDI504PI 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 IXDI504PI is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Substitute parts must maintain compatibility across driven configuration, channel type, package form factor, and critical electrical parameters to ensure functional equivalence in gate driving applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IXDI504PI is determined by the following mandatory parameters:

• Driven Configuration: Must be Low-Side
• Channel Type: Must be Independent
• 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

Secondary parameters that influence substitution suitability include supply voltage range, peak output current capability, logic voltage thresholds, rise/fall time characteristics, and operating temperature range. Substitute parts are grouped based on their ability to meet or exceed the primary electrical and mechanical requirements of the IXDI504PI within the constraints of their specified operating ranges.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Highest Compatibility)

IXDI604PI and UCC27323P provide the closest functional equivalence to the IXDI504PI. Both maintain identical peak output current specifications (4A source, 4A sink), matching rise/fall time characteristics (9ns/8ns and 20ns/15ns respectively), and support the full gate type range including IGBT. IXDI604PI is manufactured by the same supplier (IXYS) with active product status and ROHS3 compliance. UCC27323P, manufactured by Texas Instruments, carries Last Time Buy status but maintains extended operating temperature range (-55°C ~ 150°C TJ) and ROHS3 compliance.

Secondary Substitutes (Acceptable with Parameter Verification)

IXDI602PI offers superior rise/fall time performance (7.5ns/6.5ns) and extended supply voltage range (4.5V ~ 35V) but provides reduced peak output current (2A source, 2A sink). This part is suitable for applications where output current requirements do not exceed 2A and faster switching transitions are beneficial. IXDI602PI maintains IXYS manufacturer continuity and active product status with ROHS3 compliance.

IR4426PBF and MAX626EPA+ are viable substitutes for applications with reduced output current demands. IR4426PBF limits peak output current to 2.3A source and 3.3A sink with narrower supply voltage range (6V ~ 20V). MAX626EPA+ provides 2A peak output current with the most restrictive supply voltage range (4.5V ~ 18V) and narrower operating temperature range (-40°C ~ 85°C TA). Both maintain 8-DIP package compatibility and active product status.

Limited Substitutes (Marginal Compatibility)

TSC426CPA+ and UCC37323P present significant current limitations. TSC426CPA+ provides only 1.5A peak output current and operates within 0°C ~ 70°C temperature range, making it unsuitable for high-current or extended-temperature applications. UCC37323P shares identical electrical specifications with UCC27323P but carries Last Time Buy status, indicating limited future availability.

Product Status Considerations

The IXDI504PI obsolete status necessitates substitute selection. IXDI602PI and IXDI604PI offer manufacturer continuity with active product status. IR4426PBF, MAX626EPA+, MAX626CPA+, and TSC426CPA+ maintain active status from alternative manufacturers. UCC27323P and UCC37323P carry Last Time Buy designation, indicating these parts will reach end-of-life and should be considered transitional solutions only.

Frequently Asked Questions (FAQ)

Q: Can IXDI604PI directly replace IXDI504PI in existing designs?

A: IXDI604PI is a direct functional equivalent. Both parts share identical peak output current (4A/4A), rise/fall time characteristics (9ns/8ns), and support IGBT and MOSFET gate types. The primary difference is operating temperature range: IXDI504PI operates to 150°C junction temperature while IXDI604PI operates to 125°C ambient temperature. Verify your application's thermal requirements before substitution.

Q: What is the impact of reduced peak output current in substitute parts?

A: Peak output current determines the maximum gate charge delivery rate. IXDI602PI (2A), MAX626EPA+ (2A), and TSC426CPA+ (1.5A) provide reduced current compared to IXDI504PI (4A). Lower output current increases gate charging time, potentially reducing switching frequency capability or increasing switching losses. Verify gate charge requirements and switching frequency specifications before selecting lower-current alternatives.

Q: Are all substitute parts RoHS3 compliant?

A: IXDI602PI, IXDI604PI, MAX626EPA+, MAX626CPA+, TSC426CPA+, UCC27323P, and UCC37323P are specified as ROHS3 compliant. IR4426PBF does not specify RoHS status in provided documentation. Confirm RoHS compliance requirements for your application before final part selection.

Q: How do logic voltage thresholds affect substitution?

A: Logic voltage thresholds (VIL, VIH) determine input signal recognition levels. IXDI504PI specifies 0.8V/3V thresholds. UCC27323P and UCC37323P use 1V/2V thresholds, requiring higher input signal levels for reliable operation. Verify your control circuit output voltage compatibility with selected substitute part thresholds.

Q: What is the significance of Last Time Buy status for UCC27323P and UCC37323P?

A: Last Time Buy status indicates these parts will reach end-of-life production. While currently available, future procurement may become difficult or impossible. For new designs requiring long-term component availability, select IXDI602PI, IXDI604PI, or other active-status alternatives.

Q: Can substitute parts with narrower supply voltage ranges be used in applications requiring 30V operation?

A: No. IXDI504PI supports 4.5V ~ 30V supply range. Substitute parts with narrower ranges (IR4426PBF: 6V ~ 20V; MAX626EPA+: 4.5V ~ 18V; UCC27323P: 4.5V ~ 15V) cannot operate at 30V supply voltage. Only IXDI602PI (4.5V ~ 35V) and IXDI604PI (4.5V ~ 35V) support the full 30V requirement. Verify your supply voltage specification before substitution.

Q: Is package compatibility guaranteed across all substitute parts?

A: All listed substitute parts use 8-DIP (0.300", 7.62mm) through-hole packaging, ensuring mechanical and electrical pin compatibility. PCB layout modifications are not required for package substitution. Verify pinout compatibility in device datasheets before final assembly.
