IXDD414CI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDD414CI is a low-side gate driver IC manufactured by IXYS, designed for driving IGBT, N-Channel, and P-Channel MOSFET devices. This non-inverting TO-220-5 package component operates across a supply voltage range of 4.5V to 35V and delivers peak output currents of 14A for both source and sink configurations. The IXDD414CI is currently classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXDD414CI is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Driven Configuration: Low-Side
• Channel Type: Single
• Number of Drivers: 1
• Gate Type: IGBT, N-Channel, P-Channel MOSFET
• Voltage - Supply: 4.5V ~ 35V
• Current - Peak Output (Source, Sink): 14A, 14A
• Input Type: Non-Inverting
• Package / Case: TO-220-5
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 150°C (TJ)

The IXDD614CI qualifies as a direct substitute based on full alignment with all mandatory parameters. Minor variations in logic voltage thresholds (VIH: 4.6V vs. 3V) and rise/fall time characteristics (25ns/22ns vs. 25ns/18ns) remain within acceptable operational tolerances for low-side gate driver applications and do not compromise functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The IXDD614CI is the qualified substitute for the obsolete IXDD414CI. Both components maintain identical electrical specifications for supply voltage, output current capability, and operating temperature range. The IXDD614CI offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the IXDD614CI carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for new designs and production systems.

The minor reduction in fall time (22ns to 18ns) on the IXDD614CI represents an improvement in switching performance without introducing compatibility concerns. The logic voltage threshold variation (VIH: 4.6V to 3V) remains within standard TTL/CMOS input specifications and does not affect functional operation in typical gate driver applications.

Frequently Asked Questions (FAQ)

Q: Can the IXDD614CI directly replace the IXDD414CI in existing designs?

A: Yes. Both components share identical package geometry (TO-220-5), pinout configuration, and electrical operating parameters. Pin-for-pin substitution is supported without circuit modification.

Q: What is the significance of the product status difference?

A: The IXDD414CI is classified as obsolete, indicating discontinued manufacturing and limited availability. The IXDD614CI maintains active status, ensuring reliable supply chain access and ongoing manufacturer support for production and field service applications.

Q: Are there compliance differences between these parts?

A: The IXDD614CI is ROHS3 compliant, meeting current environmental directives for electronic components. Both parts maintain REACH Unaffected status. For new designs subject to environmental compliance requirements, the IXDD614CI is the appropriate selection.

Q: Do the timing differences affect circuit performance?

A: The IXDD614CI exhibits faster fall time (18ns vs. 22ns), which represents improved switching performance. This characteristic does not introduce compatibility issues and may provide marginal benefits in high-frequency switching applications.

Q: Is the logic voltage threshold change significant?

A: The VIH reduction from 4.6V to 3V remains within standard logic input specifications. This variation does not compromise functional compatibility in applications using standard TTL or CMOS logic signal sources.
