IXDD504PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDD504PI 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 dual independent channels in an 8-DIP package. The IXDD504PI is currently classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity.

Parameter Comparison

Engineering Selection Recommendations

IXDD604PI (Primary Substitute)

The IXDD604PI is the closest functional equivalent to the IXDD504PI. Both devices share identical driver channel configuration (2 independent channels), gate type support (IGBT and MOSFET), input type (non-Inverting), and switching characteristics (9ns rise time, 8ns fall time). The IXDD604PI operates across a wider supply voltage range (4.5V ~ 35V versus 4.5V ~ 30V) and maintains the same peak output current (4A source/sink). The IXDD604PI is currently Active with ROHS3 compliance, providing long-term availability and regulatory alignment. Operating temperature range is reduced to -40°C ~ 125°C (TA) compared to the IXDD504PI's -55°C ~ 150°C (TJ), which may require thermal evaluation in extreme temperature applications.

MIC4420YN (Secondary Substitute)

The MIC4420YN from Microchip Technology is a single-channel low-side gate driver suitable for applications requiring only one independent driver channel. This device provides higher peak output current (6A source/sink) and maintains the same non-inverting input configuration. The MIC4420YN operates within a narrower supply voltage range (4.5V ~ 18V) and exhibits slower switching characteristics (12ns rise time, 13ns fall time) compared to the IXDD504PI. The device is Active with ROHS3 compliance and supports the full operating temperature range of -40°C ~ 150°C (TJ). Selection of MIC4420YN requires circuit redesign if dual independent channels are required.

UCC27424P (Tertiary Substitute)

The UCC27424P from Texas Instruments maintains the dual independent channel configuration (2 drivers) and non-inverting input type of the IXDD504PI. This device provides equivalent peak output current (4A source/sink) and operates within a constrained supply voltage range (4V ~ 15V). The UCC27424P exhibits significantly slower switching characteristics (20ns rise time, 15ns fall time) and operates within a reduced temperature range (-40°C ~ 125°C TA). The device is classified as Last Time Buy, indicating limited future availability. UCC27424P selection is appropriate only when supply voltage constraints are compatible and switching speed requirements are less stringent.

Frequently Asked Questions (FAQ)

Q: Can the IXDD604PI directly replace the IXDD504PI without circuit modifications?

A: The IXDD604PI is pin-compatible and functionally equivalent for most applications. Both devices use the same 8-DIP package, share identical driver channel configuration, and support the same gate types. The primary design consideration is the reduced operating temperature range of the IXDD604PI (-40°C ~ 125°C TA versus -55°C ~ 150°C TJ). Applications operating below -40°C or above 125°C require thermal analysis to confirm compatibility.

Q: Why is MIC4420YN listed as a substitute if it has only one driver channel?

A: The MIC4420YN is functionally equivalent for applications requiring a single low-side gate driver. It maintains the same non-inverting input configuration, 8-DIP package, and through-hole mounting. However, designs utilizing both independent channels of the IXDD504PI require either dual MIC4420YN devices or selection of a dual-channel substitute such as IXDD604PI or UCC27424P.

Q: What are the key differences in switching performance between these substitutes?

A: The IXDD504PI and IXDD604PI share identical switching characteristics (9ns rise time, 8ns fall time). The MIC4420YN exhibits slower switching (12ns rise time, 13ns fall time), while the UCC27424P is significantly slower (20ns rise time, 15ns fall time). Applications with stringent switching speed requirements should prioritize IXDD604PI. Applications with relaxed switching speed requirements may accommodate MIC4420YN or UCC27424P.

Q: Are all substitute parts RoHS compliant?

A: The IXDD604PI, MIC4420YN, and UCC27424P are all ROHS3 compliant. The original IXDD504PI RoHS status is not specified in available documentation. All four devices are REACH Unaffected.

Q: What supply voltage range should I consider when selecting a substitute?

A: The IXDD504PI operates from 4.5V to 30V. The IXDD604PI extends this range to 35V, providing greater flexibility. The MIC4420YN is limited to 4.5V ~ 18V, and the UCC27424P operates within 4V ~ 15V. Designs operating above 18V should use IXDD604PI. Designs operating above 15V but below 18V may use MIC4420YN if single-channel operation is acceptable.

Q: Can I use UCC27424P in a new design given its Last Time Buy status?

A: UCC27424P is classified as Last Time Buy, indicating that Texas Instruments will discontinue production. While current inventory is available (5226 Pcs), this status restricts its use to legacy design support or short-term production runs. New designs should prioritize IXDD604PI (Active status) for long-term supply assurance.
