MIC4469BWM Equivalent & Substitute Parts

Part Overview

The MIC4469BWM is a low-side gate driver IC manufactured by Microchip Technology, designed to drive N-Channel and P-Channel MOSFETs with independent channel configuration. This 16-SOIC surface mount device operates across a 4.5V to 18V supply voltage range and delivers 1.2A peak output current for both source and sink operations.

The MIC4469BWM is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications requiring low-side gate driver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC4469BWM is determined by strict equivalence across the following electrical and mechanical parameters:

• Driven configuration (Low-Side)
• Number of independent drivers (4)
• Gate type compatibility (N-Channel, P-Channel MOSFET)
• Supply voltage range (4.5V ~ 18V)
• Peak output current specifications (1.2A source and sink)
• Input type (Inverting, Non-Inverting)
• Switching characteristics (Rise/Fall time)
• Operating temperature range (-40°C ~ 85°C)
• Package type and physical dimensions (16-SOIC, 0.295" width)

The MIC4469YWM meets all these criteria and qualifies as a direct substitute for the MIC4469BWM.

Parameter Comparison

Engineering Selection Recommendations

The MIC4469YWM is the qualified substitute for the MIC4469BWM based on the following factors:

Product Status: The MIC4469BWM is obsolete, while the MIC4469YWM is active. Selection of the MIC4469YWM ensures ongoing availability and supply chain continuity.

Compliance & Certifications: The MIC4469YWM is RoHS3 compliant, whereas the MIC4469BWM is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations. Both parts maintain REACH Unaffected status and EAR99 export classification.

Moisture Sensitivity: The MIC4469YWM has MSL 2 (1 Year), compared to the MIC4469BWM's MSL 1 (Unlimited). This represents a minor difference in moisture handling requirements during storage and assembly.

Electrical & Mechanical Equivalence: All electrical parameters, switching characteristics, and physical package dimensions are identical between the two parts, confirming direct functional substitution.

Frequently Asked Questions (FAQ)

Q: Can the MIC4469YWM directly replace the MIC4469BWM in existing designs?

A: Yes. The MIC4469YWM is electrically and mechanically equivalent to the MIC4469BWM across all specified parameters, including supply voltage, output current, switching speed, and 16-SOIC package dimensions. No circuit modifications are required.

Q: What is the primary reason to switch from MIC4469BWM to MIC4469YWM?

A: The MIC4469BWM is obsolete. The MIC4469YWM is an active product from the same manufacturer with identical electrical specifications, ensuring long-term availability and supply reliability.

Q: Are there any compliance differences between these parts?

A: Yes. The MIC4469YWM is RoHS3 compliant, while the MIC4469BWM is RoHS non-compliant. For applications requiring RoHS compliance, the MIC4469YWM is the appropriate selection. Both parts are REACH Unaffected.

Q: Do the packaging options differ between MIC4469BWM and MIC4469YWM?

A: The physical package (16-SOIC, 0.295" width) is identical. The MIC4469YWM is supplied in Tube packaging, while the MIC4469BWM packaging type was not specified. Both use the same 16-SOIC footprint for PCB assembly.

Q: What is the moisture sensitivity difference, and does it affect substitution?

A: The MIC4469YWM has MSL 2 (1 Year), while the MIC4469BWM has MSL 1 (Unlimited). This means the MIC4469YWM requires storage in controlled humidity conditions for up to one year. This does not affect functional substitution but requires adherence to proper storage and handling procedures during manufacturing.

Q: Are the electrical characteristics identical?

A: Yes. Both parts share identical supply voltage range (4.5V ~ 18V), peak output current (1.2A source and sink), logic thresholds (0.8V, 2.4V), rise/fall times (14ns, 13ns), and operating temperature range (-40°C ~ 85°C).
