Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXDI404SI-16 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Package / Case: 16-SOIC (0.295", 7.50mm Width) — physical and electrical pin compatibility
• Driven Configuration: Low-Side — functional topology requirement
• Number of Drivers: 2 — channel count requirement
• Input Type: Inverting — signal logic requirement
• Gate Type: Support for N-Channel and P-Channel MOSFET operation

Performance Parameters Affecting Substitution:

• Voltage - Supply range must encompass the application requirement
• Logic Voltage thresholds (VIL, VIH) must be compatible with control circuitry
• Current - Peak Output (Source, Sink) must meet or exceed application demands
• Rise / Fall Time affects switching speed and EMI characteristics
• Operating Temperature range must cover the thermal environment

The substitute parts identified below meet the mandatory compatibility criteria. Differences in supply voltage range, output current capability, and switching speed represent trade-offs that must be evaluated against specific application requirements.

Engineering Selection Recommendations

MIC4423YWM / MIC4423YWM-TR / MIC4423ZWM / MIC4423ZWM-TR (Microchip Technology)

These MIC4423 variants are active products with ROHS3 compliance. All share identical electrical specifications with reduced peak output current (3A versus 4A) and slower switching times (28ns/32ns versus 16ns/13ns) compared to the IXDI404SI-16. The primary distinction between variants is packaging (Tube versus Tape & Reel) and operating temperature range. MIC4423YWM and MIC4423YWM-TR support -40°C to 150°C, while MIC4423ZWM and MIC4423ZWM-TR support 0°C to 150°C. Supply voltage is limited to 4.5V ~ 18V, which is a significant constraint for applications requiring the full 35V capability of the original part.

TC4423AVOE713 (Microchip Technology)

This TC4423 variant is an active product with ROHS3 compliance and MSL 1 rating matching the original part. It provides the highest performance among substitutes with peak output current of 4.5A and the fastest switching times (12ns, 12ns). Operating temperature range is -40°C to 150°C. Like other substitutes, supply voltage is limited to 4.5V ~ 18V.

Substitution Feasibility:

All identified substitutes are electrically compatible at the functional level for applications operating within the 4.5V ~ 18V supply range. Applications requiring supply voltages above 18V cannot use these substitutes. The TC4423AVOE713 is the preferred substitute for performance-critical applications due to superior output current and switching speed. The MIC4423 variants are suitable for applications where the reduced output current and slower switching times are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the MIC4423 series replace the IXDI404SI-16 in all applications?

A: No. The MIC4423 series is limited to 4.5V ~ 18V supply voltage, while the IXDI404SI-16 operates up to 35V. Applications requiring supply voltages above 18V require alternative solutions. Within the 4.5V ~ 18V range, functional compatibility exists, but output current and switching speed differences must be evaluated.

Q: What is the impact of reduced peak output current (3A vs 4A)?

A: Peak output current determines the maximum gate charge delivery rate. Reduced current results in slower gate charging, which increases switching transition time and may increase switching losses. Applications with high-frequency switching or large gate capacitance loads may be affected. The TC4423AVOE713 with 4.5A output current provides better margin.

Q: Why do the MIC4423ZWM variants have a narrower operating temperature range (0°C ~ 150°C)?

A: Temperature range differences reflect manufacturing grade specifications. The MIC4423ZWM is a commercial-grade variant, while MIC4423YWM is an industrial-grade variant. Selection depends on the application's minimum operating temperature requirement.

Q: Are all substitutes RoHS compliant?

A: Yes. All identified substitutes are ROHS3 compliant. The original IXDI404SI-16 RoHS status is not specified in the provided data.

Q: What is the significance of MSL rating differences?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control. MSL 2 requires controlled storage (1 year maximum) to prevent moisture absorption. The TC4423AVOE713 and original IXDI404SI-16 both have MSL 1. MIC4423 variants have MSL 2, requiring proper storage management.

Q: Can packaging variants (Tube vs Tape & Reel) be used interchangeably?

A: Yes, from an electrical and functional perspective. Packaging affects handling, storage, and automated assembly compatibility. Tube packaging is suitable for manual assembly or small-volume production. Tape & Reel packaging is optimized for high-volume automated assembly. Selection depends on production methodology.

Q: What are the switching time implications of the TC4423AVOE713?

A: The TC4423AVOE713 has the fastest switching times (12ns rise and fall) among all options. This reduces switching transition time, potentially lowering EMI and switching losses. Applications sensitive to switching speed benefit from this specification.
