IX4424N Low-Side Gate Driver IC

Part Overview

The IX4424N is a low-side gate driver IC manufactured by IXYS Integrated Circuits Division, designed for driving N-Channel and P-Channel MOSFETs in power management applications. This device features non-inverting logic, independent dual-channel configuration, and operates across a 4.5V to 30V supply voltage range. The IX4424N is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IX4424N is based on strict alignment of the following critical parameters:

• Driven Configuration: Low-Side (must match)
• Channel Type: Independent dual-channel (must match)
• Gate Type: N-Channel and P-Channel MOSFET support (must match)
• Input Type: Non-Inverting logic (must match)
• Package / Case: 8-SOIC form factor (must match)
• Mounting Type: Surface Mount (must match)

The IX4427N qualifies as a substitute based on identical driven configuration, channel type, gate type, input logic, package form factor, and mounting technology. Both devices maintain compatibility with the same PCB footprint and signal interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The IX4427N is the manufacturer-recommended substitute for the obsolete IX4424N. Both devices share identical functional architecture, package form factor, and supply voltage specifications. The IX4427N maintains active product status, ensuring long-term availability and manufacturing support.

Key differences exist in output current capability, switching speed, and operating temperature range. The IX4427N delivers reduced peak output current (1.5A versus 3A) and faster switching transitions (10ns/8ns versus 18ns/18ns). The IX4427N operates across a narrower temperature range (-40°C to 125°C) compared to the IX4424N (-55°C to 150°C).

Selection of the IX4427N is appropriate for applications where the reduced output current and narrower temperature specification align with system requirements. Both devices maintain ROHS3 compliance and unlimited moisture sensitivity classification, supporting equivalent environmental and regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can the IX4427N directly replace the IX4424N in existing designs?

A: The IX4427N shares identical package footprint, supply voltage range, and logic interface with the IX4424N. Direct PCB substitution is possible. However, the reduced peak output current (1.5A versus 3A) and narrower operating temperature range (-40°C to 125°C versus -55°C to 150°C) must be evaluated against application requirements.

Q: What are the key parameter differences between these devices?

A: The primary differences are peak output current (3A versus 1.5A), switching speed (18ns versus 10ns/8ns rise/fall times), logic voltage threshold (VIH 3V versus 2.4V), and operating temperature range. Supply voltage, package, and functional configuration remain identical.

Q: Are both devices RoHS and REACH compliant?

A: Yes. Both the IX4424N and IX4427N are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What is the packaging difference between these parts?

A: Both devices use 8-SOIC surface-mount packaging with identical 0.154" (3.90mm) width. No PCB layout modifications are required for substitution.

Q: Why is the IX4424N obsolete?

A: The IX4424N is classified as obsolete by the manufacturer. The IX4427N represents the active product line continuation, ensuring ongoing availability and manufacturing support for low-side gate driver applications.
