IXDF504PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDF504PI is a low-side gate driver IC manufactured by IXYS, designed for driving IGBT and MOSFET gates in power management applications. This device features dual independent channels with inverting and non-inverting input configurations, operating across a 4.5V to 30V supply range with 4A peak output current capability.

The IXDF504PI is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this gate driver topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IXDF504PI is determined by the following critical parameters:

Primary Compatibility Criteria:

• Driven Configuration: Low-Side
• Number of Drivers: 2 (dual channel)
• Input Type: Inverting, Non-Inverting
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

Electrical Compatibility Criteria:

• Gate Type: IGBT and/or MOSFET (N-Channel, P-Channel)
• Voltage - Supply: Must support minimum 4.5V and accommodate application requirements
• Current - Peak Output: Must meet or exceed application drive current demands
• Logic Voltage Thresholds: VIL and VIH must be compatible with control signal levels

Substitute parts are grouped into two categories based on electrical performance alignment:

Category A - Direct Performance Match: IXDF604PI maintains identical peak output current (4A/4A), rise/fall time characteristics (9ns/8ns), and supports the same gate types. Supply voltage range extends to 35V, providing enhanced flexibility.

Category B - Reduced Output Current: IXDF602PI provides 2A peak output current, suitable for lower-power gate drive applications. Rise/fall times are improved (7.5ns/6.5ns), and supply voltage range extends to 35V.

Category C - Alternative Topology: UCC27325P and UCC37325P offer 4A peak output current with extended rise/fall times (20ns/15ns). Supply voltage range is limited to 4.5V ~ 15V, restricting application scope compared to IXDF series devices.

Parameter Comparison

Engineering Selection Recommendations

IXDF604PI is the primary substitute for IXDF504PI applications. This part maintains active product status with ROHS3 compliance. Electrical performance is identical to the original part, with extended supply voltage range (4.5V ~ 35V) providing design margin. Operating temperature range is specified at -40°C ~ 125°C (TA), which is narrower than the original part's -55°C ~ 150°C (TJ) specification. This part is suitable for applications where the reduced temperature range is acceptable.

IXDF602PI is a substitute for applications requiring lower gate drive current. This part is active with ROHS3 compliance and provides improved rise/fall time performance (7.5ns/6.5ns). The 2A peak output current is suitable for lower-power MOSFET and IGBT gate drive circuits. Extended supply voltage range (4.5V ~ 35V) is available. This part maintains the full operating temperature range (-55°C ~ 150°C).

UCC27325P and UCC37325P are alternative substitutes with 4A peak output current capability. Both parts support the required dual-channel, low-side configuration with inverting and non-inverting inputs. Supply voltage range is limited to 4.5V ~ 15V, which restricts application scope for higher-voltage systems. UCC37325P is designated as Last Time Buy, indicating limited future availability. Both parts maintain -55°C ~ 150°C operating temperature range.

For new designs or long-term production requirements, IXDF604PI is the recommended substitute due to active product status and performance alignment. IXDF602PI is suitable where reduced output current meets application requirements. UCC27325P and UCC37325P should be evaluated only when supply voltage requirements do not exceed 15V.

Frequently Asked Questions (FAQ)

Q: Can IXDF602PI replace IXDF504PI in all applications?

A: IXDF602PI is a functional substitute only for applications where peak gate drive current does not exceed 2A. The original IXDF504PI provides 4A peak output current. Applications requiring higher drive current must use IXDF604PI, UCC27325P, or UCC37325P.

Q: What is the primary difference between IXDF604PI and IXDF504PI?

A: IXDF604PI is an active product with identical electrical performance (4A peak output, 9ns/8ns rise/fall times). The main difference is product status: IXDF504PI is obsolete, while IXDF604PI is actively manufactured. IXDF604PI extends supply voltage range to 35V and includes ROHS3 compliance. Operating temperature range is narrower (-40°C ~ 125°C vs. -55°C ~ 150°C).

Q: Are UCC27325P and UCC37325P pin-compatible with IXDF504PI?

A: Both UCC27325P and UCC37325P use the same 8-DIP package as IXDF504PI and support dual-channel, low-side gate drive with inverting and non-inverting inputs. However, logic voltage thresholds differ (1V/2V vs. 0.8V/3V), and supply voltage range is limited to 4.5V ~ 15V. Pin-level compatibility must be verified against specific application requirements.

Q: What is the impact of different rise/fall times on gate drive performance?

A: Rise and fall times affect switching speed and electromagnetic emissions. IXDF602PI provides faster switching (7.5ns/6.5ns) compared to IXDF504PI (9ns/8ns). UCC27325P and UCC37325P have slower switching (20ns/15ns). Faster switching reduces switching losses but may increase EMI. Application circuit design must accommodate these timing differences.

Q: Is IXDF604PI suitable for applications requiring -55°C operation?

A: IXDF604PI specifies operating temperature range of -40°C ~ 125°C (TA). Applications requiring -55°C operation must use IXDF602PI (-55°C ~ 150°C) or UCC27325P/UCC37325P (-55°C ~ 150°C). Temperature range specifications must be verified against application requirements.

Q: What compliance certifications are available for substitute parts?

A: IXDF604PI and IXDF602PI are ROHS3 compliant. UCC37325P is ROHS3 compliant. All parts are REACH unaffected and classified as EAR99 for export control purposes. Specific compliance requirements for your application must be verified independently.

Q: Can IXDF504PI be used in applications exceeding 30V supply voltage?

A: IXDF504PI is rated for 4.5V ~ 30V supply voltage. Applications requiring higher supply voltage must use IXDF604PI or IXDF602PI (both rated 4.5V ~ 35V). UCC27325P and UCC37325P are limited to 4.5V ~ 15V and are not suitable for higher-voltage applications.
