Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC4468CWM is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side operation
• Number of Drivers: 4 independent channels
• Gate Type: N-Channel and P-Channel MOSFET compatibility
• Supply Voltage Range: 4.5V ~ 18V
• Peak Output Current: 1.2A source and sink capability
• Input Logic: Non-Inverting configuration
• Package: 16-SOIC surface mount form factor
• Switching Performance: Rise/Fall time specifications (14ns/13ns typical)

The MIC4468ZWM qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction between these parts is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MIC4468ZWM is the direct substitute for the obsolete MIC4468CWM. Both parts are manufactured by Microchip Technology and provide identical electrical performance and pinout compatibility.

Product Status Consideration: The MIC4468CWM is obsolete, whereas the MIC4468ZWM maintains active production status. For new designs and ongoing production support, the MIC4468ZWM is the appropriate selection.

Compliance Advantage: The MIC4468ZWM achieves ROHS3 compliance, whereas the MIC4468CWM is RoHS non-compliant. Applications subject to RoHS regulatory requirements must use the MIC4468ZWM.

Moisture Sensitivity: The MIC4468ZWM carries MSL 2 (1 Year) rating compared to MSL 1 (Unlimited) for the MIC4468CWM. This represents a minor difference in moisture handling requirements during storage and assembly.

Both parts are electrically and mechanically interchangeable for applications requiring a four-channel low-side gate driver with the specified electrical characteristics and 16-SOIC package.

Frequently Asked Questions (FAQ)

Q: Are the MIC4468CWM and MIC4468ZWM pin-compatible?

A: Yes. Both parts use the 16-SOIC package with identical pinout and electrical specifications. Direct substitution is possible without circuit modification.

Q: What is the primary reason to substitute the MIC4468CWM?

A: The MIC4468CWM is obsolete. The MIC4468ZWM provides equivalent functionality with active production status and improved compliance certifications.

Q: Does the MIC4468ZWM meet RoHS requirements?

A: Yes. The MIC4468ZWM is ROHS3 compliant. The MIC4468CWM is RoHS non-compliant and cannot be used in applications with RoHS regulatory requirements.

Q: Are there differences in electrical performance between these parts?

A: No. Both parts provide identical supply voltage range (4.5V ~ 18V), peak output current (1.2A source/sink), switching times (14ns/13ns), and logic thresholds (0.8V/2.4V).

Q: What is the difference in Moisture Sensitivity Level (MSL)?

A: The MIC4468CWM carries MSL 1 (Unlimited), while the MIC4468ZWM carries MSL 2 (1 Year). MSL 2 requires storage in controlled humidity conditions and use within one year of manufacture. This is a standard industry practice and does not affect circuit performance.

Q: Can I use the MIC4468ZWM as a drop-in replacement in existing designs?

A: Yes. The MIC4468ZWM is a direct substitute with identical package, pinout, and electrical specifications. No design changes are required.
