Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC4467BWM is determined by strict equivalence across the following critical parameters:

• Driven configuration (low-side operation)
• Independent channel type with 4 drivers
• Gate type compatibility (N-Channel and P-Channel MOSFET support)
• Supply voltage range (4.5V ~ 18V)
• Logic voltage thresholds (VIL 0.8V, VIH 2.4V)
• Peak output current (1.2A source and sink)
• Input type (inverting)
• Timing characteristics (rise/fall time 14ns/13ns)
• Operating temperature range (-40°C ~ 85°C)
• Package specification (16-SOIC surface mount)

The MIC4467YWM meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The MIC4467YWM is the qualified substitute for the obsolete MIC4467BWM. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in gate driver applications.

Key differentiators between the two parts:

• Product Status: MIC4467YWM is active and currently manufactured, while MIC4467BWM is obsolete and no longer in production.
• RoHS Compliance: MIC4467YWM meets ROHS3 compliance requirements, whereas MIC4467BWM is non-compliant. This distinction is critical for applications subject to RoHS regulations.
• Moisture Sensitivity: MIC4467YWM carries MSL 2 (1 Year), compared to MIC4467BWM MSL 1 (Unlimited). This affects storage and handling requirements.

For new designs or production transitions, MIC4467YWM is the appropriate selection. For legacy systems currently using MIC4467BWM, substitution with MIC4467YWM is electrically and mechanically compatible.

Frequently Asked Questions (FAQ)

Q: Are MIC4467BWM and MIC4467YWM pin-compatible?

A: Yes. Both devices use the 16-SOIC package with identical pinout and electrical characteristics, enabling direct substitution without circuit modification.

Q: What is the primary reason to substitute MIC4467BWM with MIC4467YWM?

A: MIC4467BWM is obsolete and no longer manufactured. MIC4467YWM is the active equivalent from Microchip Technology with identical functional specifications.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical gate driver functionality.

Q: How does the MSL rating difference impact component handling?

A: MIC4467YWM (MSL 2, 1 Year) requires storage in controlled humidity conditions and has a one-year shelf life from the date of manufacture. MIC4467BWM (MSL 1, Unlimited) has no moisture sensitivity restrictions. Proper storage procedures must be followed for MIC4467YWM to maintain reliability.

Q: Can MIC4467YWM be used in applications originally designed for MIC4467BWM?

A: Yes. Electrical and mechanical specifications are identical. Substitution is direct and requires no design changes.

Q: Are there any supply voltage or current limitations that differ between these parts?

A: No. Both parts operate across 4.5V to 18V supply range with identical 1.2A peak output current (source and sink).
