IXDD414PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDD414PI is a low-side gate driver IC manufactured by IXYS, designed for driving IGBT, N-Channel, and P-Channel MOSFET devices. This non-inverting 8-DIP through-hole component operates across a wide supply voltage range of 4.5V to 35V and delivers peak output currents of 14A for both source and sink configurations. The device is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations where legacy component replacement is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXDD414PI is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side operation only
• Channel Type: Single channel
• Gate Type: IGBT, N-Channel, P-Channel MOSFET compatibility
• Supply Voltage Range: 4.5V ~ 35V minimum requirement
• Peak Output Current: 14A source and sink capability
• Input Type: Non-Inverting logic
• Package / Case: 8-DIP (0.300", 7.62mm) through-hole form factor
• Mounting Type: Through Hole

The IXDD614PI meets all substitution criteria as a direct equivalent. Both devices share identical driven configuration, channel architecture, gate type support, supply voltage specifications, output current ratings, input logic type, and physical packaging. Differences in logic voltage thresholds (VIH: 4.6V vs 3V) and rise/fall time characteristics (25ns/22ns vs 25ns/18ns) remain within acceptable operational margins for low-side gate driver applications and do not preclude functional substitution.

Engineering Selection Recommendations

The IXDD614PI is a direct functional substitute for the obsolete IXDD414PI. Selection of the IXDD614PI is supported by the following engineering factors:

• Product Status Alignment: The IXDD614PI maintains active product status, ensuring continued availability and manufacturer support, whereas the IXDD414PI is obsolete.
• Regulatory Compliance: The IXDD614PI is ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and system updates.
• Electrical Equivalence: Both devices maintain identical supply voltage ranges, output current specifications, and operating temperature ranges across the full -55°C to 150°C junction temperature spectrum.
• Physical Compatibility: Identical 8-DIP through-hole packaging ensures direct PCB footprint compatibility without layout modifications.
• Performance Enhancement: The IXDD614PI exhibits improved fall time characteristics (18ns vs 22ns), providing marginal performance benefit in switching applications.

Frequently Asked Questions (FAQ)

Q: Can the IXDD614PI be used as a direct replacement for the IXDD414PI in existing designs?

A: Yes. The IXDD614PI is electrically and mechanically equivalent to the IXDD414PI. Both devices share identical package geometry (8-DIP), pinout configuration, supply voltage range (4.5V ~ 35V), output current ratings (14A source/sink), and gate type support (IGBT, N-Channel, P-Channel MOSFET). Direct PCB substitution is possible without circuit modifications.

Q: What are the differences between the IXDD414PI and IXDD614PI?

A: The primary differences are product status and compliance certifications. The IXDD414PI is obsolete, while the IXDD614PI is active. The IXDD614PI is ROHS3 compliant. Minor electrical differences include logic voltage threshold VIH (4.6V vs 3V) and fall time (22ns vs 18ns), both of which remain within acceptable operational margins for low-side gate driver applications.

Q: Are there any pinout differences between these devices?

A: No. Both the IXDD414PI and IXDD614PI use identical 8-DIP pinout configurations. Pin-for-pin compatibility is confirmed, allowing direct socket substitution.

Q: What is the impact of the VIH logic voltage difference (4.6V vs 3V)?

A: The IXDD614PI has a lower VIH threshold (3V vs 4.6V), which represents improved input sensitivity. This difference does not create compatibility issues in standard gate driver applications and may provide marginal benefit in systems with lower logic signal levels.

Q: Does the improved fall time of the IXDD614PI (18ns vs 22ns) affect circuit performance?

A: The IXDD614PI's faster fall time (18ns) compared to the IXDD414PI (22ns) represents a 4ns improvement. This enhancement may provide marginal benefits in high-frequency switching applications but does not preclude substitution in existing designs rated for the original 22ns specification.

Q: Is the IXDD614PI suitable for new product designs?

A: Yes. The IXDD614PI is the recommended choice for new designs. It maintains active product status, offers ROHS3 compliance, and provides equivalent or superior electrical performance compared to the obsolete IXDD414PI.

Q: What packaging options are available for the IXDD614PI?

A: The IXDD614PI is supplied in Tube packaging for the 8-DIP form factor. The original IXDD414PI packaging specification was not detailed; however, both devices share identical 8-DIP (0.300", 7.62mm) case geometry.
