Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC4469BWM TR is determined by strict equivalence across the following critical parameters:

• Driven configuration (low-side operation)
• Number of independent drivers (4 channels)
• Gate type compatibility (N-Channel and P-Channel MOSFET support)
• Supply voltage range (4.5V ~ 18V)
• Peak output current specifications (1.2A source and sink)
• Input configuration (inverting and non-inverting)
• Package type (16-SOIC form factor)
• Rise and fall time characteristics (14ns, 13ns)
• Operating temperature range (-40°C ~ 85°C)

The MIC4469YWM-TR qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all these parameters.

Parameter Comparison

Engineering Selection Recommendations

The MIC4469YWM-TR is a direct electrical and mechanical equivalent to the MIC4469BWM TR. All functional parameters, electrical specifications, and package dimensions are identical.

Key differentiators between the two parts:

• The MIC4469YWM-TR carries active product status, ensuring ongoing manufacturer support and availability, whereas the MIC4469BWM TR is obsolete.
• The MIC4469YWM-TR is ROHS3 compliant, meeting current environmental and regulatory requirements. The MIC4469BWM TR is RoHS non-compliant.
• The MIC4469YWM-TR has a Moisture Sensitivity Level (MSL) of 2 with a 1-year shelf life requirement. The MIC4469BWM TR has MSL 1 with unlimited shelf life.

For new designs and ongoing production, the MIC4469YWM-TR is the appropriate selection due to its active status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the MIC4469YWM-TR be used as a direct replacement for the MIC4469BWM TR in existing designs?

A: Yes. All electrical specifications, pin configurations, and package dimensions are identical. No circuit modifications are required for substitution.

Q: Are there any differences in gate driver performance between these parts?

A: No. Both parts deliver identical peak output current (1.2A source and sink), rise and fall times (14ns and 13ns respectively), and operate across the same supply voltage range (4.5V ~ 18V).

Q: What is the significance of the RoHS compliance difference?

A: The MIC4469YWM-TR meets ROHS3 compliance standards, which restricts hazardous substances in electrical and electronic equipment. This is required for products sold in regulated markets. The MIC4469BWM TR does not meet these standards.

Q: Does the Moisture Sensitivity Level (MSL) difference affect circuit performance?

A: MSL affects storage and handling requirements, not circuit performance. The MIC4469YWM-TR (MSL 2) requires controlled humidity storage with a 1-year shelf life limit. The MIC4469BWM TR (MSL 1) has no shelf life restriction. Both parts perform identically once soldered into the circuit.

Q: Are both parts available in the same packaging format?

A: Yes. Both the MIC4469BWM TR and MIC4469YWM-TR are supplied in 16-SOIC packages with Tape & Reel (TR) packaging, maintaining identical PCB footprints and assembly compatibility.

Q: Why is the MIC4469BWM TR classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The MIC4469YWM-TR is the active replacement, ensuring continued availability and manufacturer support for this gate driver topology.
