IX4425MTR Equivalent & Substitute Parts

Part Overview

The IX4425MTR is a low-side gate driver IC manufactured by IXYS Integrated Circuits Division, designed for independent dual-channel N-Channel and P-Channel MOSFET gate driving applications. This component operates with a non-inverting input configuration and delivers 3A peak output current (source and sink). The IX4425MTR is classified as obsolete, making identification of functionally compatible substitute parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitute parts for the IX4425MTR are identified based on the following critical parameters that define functional compatibility:

• Driven Configuration: Low-Side operation
• Number of Drivers: Dual independent channels
• Gate Type: N-Channel and P-Channel MOSFET support
• Supply Voltage Range: 4.5V ~ 30V compatibility
• Channel Independence: Independent channel operation
• RoHS Compliance: ROHS3 Compliant status

The IX4428MTR qualifies as a substitute based on matching driven configuration, dual independent channels, gate type support, and supply voltage range. Differences in peak output current, input type flexibility, and operating temperature range are noted in the parameter comparison below.

Parameter Comparison

Engineering Selection Recommendations

The IX4428MTR is an active product substitute for the obsolete IX4425MTR. Both components share identical supply voltage ranges (4.5V ~ 30V), dual independent low-side gate driver configuration, and support for N-Channel and P-Channel MOSFET gate driving. Both maintain ROHS3 compliance and are manufactured by IXYS Integrated Circuits Division.

Selection of the IX4428MTR requires evaluation of the following differences:

• Peak Output Current: The IX4428MTR provides 1.5A peak output (source and sink) compared to 3A for the IX4425MTR. Applications requiring the full 3A output capability must confirm that 1.5A is sufficient for the target MOSFET gate charge requirements.
• Input Type Flexibility: The IX4428MTR supports both inverting and non-inverting input configurations, whereas the IX4425MTR is non-inverting only. This provides additional design flexibility with the substitute part.
• Operating Temperature Range: The IX4425MTR operates to 150°C (junction temperature), while the IX4428MTR operates to 125°C (ambient temperature). Applications requiring extended high-temperature operation must verify compatibility.
• Switching Speed: The IX4428MTR exhibits faster rise and fall times (10ns, 8ns) compared to the IX4425MTR (18ns, 18ns).

The IX4428MTR is recommended for new designs and procurement where the reduced peak output current and operating temperature range are compatible with application requirements.

Frequently Asked Questions (FAQ)

Q: Can the IX4428MTR directly replace the IX4425MTR in existing designs?

A: Direct replacement is possible if the application peak output current requirement does not exceed 1.5A. The IX4428MTR provides identical supply voltage range, dual independent channels, and low-side gate driver configuration. Verify that the target MOSFET gate charge can be driven within the 1.5A output current specification.

Q: What is the impact of the different operating temperature ranges?

A: The IX4425MTR operates to 150°C junction temperature, while the IX4428MTR operates to 125°C ambient temperature. Applications operating above 125°C ambient must confirm that the IX4428MTR junction temperature remains within specification under worst-case thermal conditions.

Q: Does the IX4428MTR support non-inverting input operation?

A: Yes. The IX4428MTR supports both inverting and non-inverting input configurations. The IX4425MTR is non-inverting only. Existing non-inverting input designs can use the IX4428MTR without modification.

Q: Are there packaging differences between these parts?

A: The IX4425MTR packaging is not specified in the provided data. The IX4428MTR is supplied in 8-VDFN Exposed Pad (3x3) package in Cut Tape (CT) and Digi-Reel® formats. Verify package compatibility with existing PCB designs and assembly processes.

Q: What is the significance of the faster switching times in the IX4428MTR?

A: The IX4428MTR exhibits rise and fall times of 10ns and 8ns respectively, compared to 18ns for both parameters in the IX4425MTR. Faster switching times reduce gate driver propagation delay and may improve MOSFET switching performance. Verify that faster switching times do not introduce noise or EMI concerns in the target application.

Q: Are both parts RoHS compliant?

A: Yes. Both the IX4425MTR and IX4428MTR are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic component procurement.
