IX4424NTR Equivalent & Substitute Parts

Part Overview

The IX4424NTR 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 operates with a supply voltage range of 4.5V to 30V and features non-inverting logic inputs with independent dual-channel configuration in an 8-SOIC surface mount package.

The IX4424NTR is classified as obsolete, which necessitates identification of active substitute components that maintain functional and electrical compatibility for new designs or production continuity. The IX4427NTR serves as the manufacturer-recommended substitute, offering equivalent packaging and core functionality with updated electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

The IX4427NTR qualifies as a direct substitute for the IX4424NTR based on the following alignment of critical parameters:

Matching Parameters:

• Driven configuration: Low-side
• Number of drivers: 2 independent channels
• Gate type: N-Channel and P-Channel MOSFET support
• Input type: Non-inverting logic
• Supply voltage range: 4.5V ~ 30V
• Package: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface mount
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The IX4427NTR maintains functional equivalence in all core electrical and mechanical specifications required for gate driver operation. Both devices are manufactured by IXYS Integrated Circuits Division and share identical packaging, pinout compatibility, and supply voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

The IX4427NTR is the active manufacturer substitute for the obsolete IX4424NTR. Both devices maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility.

Selection between these parts depends on application-specific requirements:

Use IX4427NTR when:

• Active component availability is required for production continuity
• Peak output current requirements do not exceed 1.5A per channel
• Operating temperature range of -40°C to 125°C is acceptable
• Faster switching characteristics (10ns/8ns rise/fall time) are beneficial or acceptable

Use IX4424NTR when:

• Existing inventory is available and design is locked
• Peak output current of 3A per channel is required
• Extended temperature operation to 150°C (junction) is necessary
• Slower switching characteristics are acceptable or required

Both devices are pin-compatible in 8-SOIC packaging and support identical supply voltage ranges (4.5V ~ 30V), enabling direct substitution at the board level without layout modifications.

Frequently Asked Questions (FAQ)

Q: Are IX4424NTR and IX4427NTR pin-compatible?

A: Yes. Both devices use the 8-SOIC (0.154", 3.90mm Width) package with identical pinout. Direct board-level substitution is possible without PCB redesign.

Q: What are the key electrical differences between these parts?

A: The IX4427NTR has lower peak output current (1.5A vs. 3A), faster switching times (10ns/8ns vs. 18ns/18ns), a lower logic input high threshold (2.4V vs. 3V), and a narrower operating temperature range (-40°C to 125°C vs. -55°C to 150°C).

Q: Can I use IX4427NTR in a design originally specified for IX4424NTR?

A: Substitution is valid if the application does not require peak output currents exceeding 1.5A per channel and operates within the -40°C to 125°C temperature range. The lower VIH threshold of IX4427NTR may require logic signal verification in systems with marginal input voltage levels.

Q: Are both parts RoHS compliant?

A: Yes. Both IX4424NTR and IX4427NTR are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current environmental and regulatory requirements.

Q: Why is IX4424NTR obsolete?

A: The IX4424NTR is classified as obsolete by the manufacturer. The IX4427NTR serves as the active production replacement, offering improved switching performance and maintained functional compatibility.

Q: What is the supply voltage range for both devices?

A: Both the IX4424NTR and IX4427NTR operate with a supply voltage range of 4.5V to 30V, enabling use in a wide range of power management applications.
