IXDF602PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDF602PI is a low-side gate driver IC manufactured by IXYS Integrated Circuits Division, designed for driving IGBT and MOSFET devices in power management applications. This 8-DIP through-hole component operates across a wide supply voltage range of 4.5V to 35V and supports both inverting and non-inverting input configurations with independent dual-channel architecture.

The IXDF602PI maintains active product status with 1112 units in current inventory. Substitute parts are necessary when addressing supply constraints, specific application requirements, or when transitioning to alternative manufacturer sourcing while maintaining functional compatibility within the electrical and mechanical constraints of the application.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the IXDF602PI is determined by the following critical parameters:

Package Compatibility: All substitute parts must use 8-DIP through-hole packaging (0.300", 7.62mm) to ensure direct PCB footprint compatibility without layout modifications.

Functional Architecture: Substitute parts must provide dual independent low-side gate driver channels with support for both inverting and non-inverting input configurations.

Gate Type Support: Substitute parts must support N-Channel and P-Channel MOSFET driving. IGBT support is not required for substitution, as this represents an extended capability of the IXDF602PI.

Supply Voltage Range: The IXDF602PI operates from 4.5V to 35V. Substitute parts with reduced maximum supply voltage (4.5V to 15V) are acceptable for applications operating within the lower voltage range, provided the application does not require the extended 35V capability.

Logic Voltage Levels: Substitute parts must accept the same logic input voltage thresholds or lower thresholds to ensure compatibility with existing control circuitry.

Output Current Capability: The IXDF602PI provides 2A peak source and sink current. Substitute parts with equal or greater output current capability maintain full functional compatibility.

Timing Characteristics: Rise and fall times are application-dependent. Substitute parts with different timing characteristics remain functionally compatible provided the application timing margins accommodate the variation.

Parameter Comparison

Engineering Selection Recommendations

UCC27325P (Unitrode): This substitute provides dual independent low-side gate driver channels in 8-DIP packaging with identical functional architecture to the IXDF602PI. The UCC27325P offers higher peak output current (4A versus 2A) and is suitable for applications operating within the 4.5V to 15V supply range. The part maintains active product status with 4327 units in inventory. The reduced supply voltage maximum (15V versus 35V) restricts this substitute to applications not requiring extended voltage operation. RoHS compliance status is not specified for this part.

UCC37325P (Texas Instruments): This substitute provides equivalent dual independent low-side gate driver functionality in 8-DIP packaging. The UCC37325P offers higher peak output current (4A versus 2A) and operates within the 4.5V to 15V supply range. This part carries ROHS3 compliance certification and maintains the full operating temperature range of -55°C to 150°C. The product status is Last Time Buy, indicating this part is no longer in active production and future availability is limited. The reduced supply voltage maximum restricts this substitute to applications not requiring extended voltage operation. Current inventory is 1402 units.

Both substitute parts are functionally compatible with the IXDF602PI for applications operating within the 4.5V to 15V supply voltage range and requiring MOSFET gate driving without IGBT support requirements.

Frequently Asked Questions (FAQ)

Q: Can UCC27325P or UCC37325P be used as direct replacements for IXDF602PI in all applications?

A: Direct substitution is limited to applications operating within the 4.5V to 15V supply voltage range. Applications requiring supply voltages above 15V must use the IXDF602PI, as the substitute parts are rated to 15V maximum. All three parts share identical 8-DIP packaging, dual-channel architecture, and support for inverting and non-inverting inputs.

Q: What is the impact of different peak output current ratings?

A: The IXDF602PI provides 2A peak source and sink current, while UCC27325P and UCC37325P provide 4A peak current. Higher output current capability in substitute parts does not create compatibility issues; the application will function correctly with the increased current margin. Applications designed for 2A output current will operate within specification using 4A-rated substitutes.

Q: Are there supply voltage considerations when substituting?

A: The IXDF602PI operates from 4.5V to 35V. Both UCC27325P and UCC37325P operate from 4.5V to 15V. If the application requires supply voltages above 15V, substitution is not possible. For applications operating at 15V or below, both substitutes are electrically compatible.

Q: What is the significance of the UCC37325P Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing production. While current inventory of 1402 units is available, future procurement may not be possible. For new designs or long-term production requirements, the IXDF602PI (Active status) or UCC27325P (Active status) are preferred to ensure sustained supply availability.

Q: Do logic voltage threshold differences affect compatibility?

A: The IXDF602PI has logic thresholds of 0.8V (VIL) and 3V (VIH), while substitutes have 1V (VIL) and 2V (VIH). These differences do not create incompatibility; control circuits designed for the IXDF602PI will function correctly with the substitute parts. The substitute thresholds represent a subset of the IXDF602PI specification.

Q: How do timing differences between parts affect circuit performance?

A: The IXDF602PI has rise/fall times of 7.5ns/6.5ns, while substitutes have 20ns/15ns. Slower switching times in substitute parts may affect high-frequency switching applications. Applications with timing margins accommodating 20ns rise and fall times will function correctly with substitutes. Applications requiring faster switching must use the IXDF602PI.
