MIC4423BWM TR Equivalent & Substitute Parts

Part Overview

The MIC4423BWM TR is a low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in independent channel configurations. This 16-SOIC surface mount device operates across a 4.5V to 18V supply voltage range with inverting input logic and dual independent driver channels.

The MIC4423BWM TR carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and access components with active manufacturing support and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC4423BWM TR is determined by strict equivalence across the following critical parameters:

• Driven configuration (low-side only)
• Number of independent driver channels (2 channels)
• Gate type compatibility (N-Channel and P-Channel MOSFET support)
• Supply voltage range (4.5V ~ 18V minimum)
• Logic voltage thresholds (VIL 0.8V, VIH 2.4V)
• Peak output current capability (3A source and sink)
• Input logic type (inverting)
• Package form factor (16-SOIC)
• Surface mount compatibility

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in rise/fall time performance, operating temperature lower bound, packaging format (Tube vs. Tape & Reel), and compliance certifications do not affect functional substitutability within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain functional equivalence to the MIC4423BWM TR across the defined electrical and mechanical parameter set. Selection among substitutes should prioritize the following factors:

Product Status: All substitute parts carry active product status, ensuring ongoing manufacturing support and availability. The MIC4423BWM TR obsolete status necessitates transition to an active alternative.

Compliance Certifications: All substitute parts are ROHS3 compliant, addressing regulatory requirements that the original MIC4423BWM TR does not meet. All parts maintain REACH unaffected status and EAR99 export classification.

Packaging Format: MIC4423YWM-TR, TC4423EOE713, and TC4423VOE713 are supplied in Tape & Reel format. TC4423EOE, TC4423VOE, and TC4423COE are supplied in Tube format. Selection depends on assembly process requirements and quantity thresholds.

Operating Temperature Range: TC4423COE specifies a 0°C lower operating bound compared to the -40°C minimum of other substitutes. This difference applies only to applications requiring extended low-temperature operation.

Performance Characteristics: TC4423 series parts (TC4423EOE, TC4423EOE713, TC4423VOE, TC4423VOE713, TC4423COE) exhibit improved rise and fall times (23ns/25ns) compared to the MIC4423 series (28ns/32ns). This performance enhancement does not affect substitutability but may provide marginal benefits in high-frequency switching applications.

Frequently Asked Questions (FAQ)

Q: Can MIC4423YWM-TR directly replace MIC4423BWM TR in existing designs?

A: Yes. MIC4423YWM-TR maintains identical electrical specifications, supply voltage range, output current capability, and 16-SOIC package form factor. The primary differences are active product status and ROHS3 compliance. Tape & Reel packaging matches the original part format.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel packaging is used for automated assembly processes and high-volume production. Tube packaging is used for manual assembly or lower-volume applications. Both formats contain the same die and electrical performance. Selection depends on manufacturing process requirements.

Q: Are TC4423 series parts functionally equivalent to MIC4423 series parts?

A: Yes. TC4423EOE, TC4423EOE713, TC4423VOE, TC4423VOE713, and TC4423COE maintain all critical electrical parameters: 4.5V to 18V supply voltage, 3A peak output current, inverting input logic, dual independent channels, and 16-SOIC package. Rise and fall time improvements in TC4423 variants do not affect functional substitutability.

Q: Does the improved rise/fall time in TC4423 parts require circuit redesign?

A: No. Faster rise and fall times (23ns/25ns versus 28ns/32ns) represent performance enhancement without introducing incompatibility. Existing circuit designs function with TC4423 substitutes without modification.

Q: Which substitute part should be selected for new designs?

A: MIC4423YWM-TR or TC4423EOE713 are recommended for new designs. Both are active products with ROHS3 compliance and Tape & Reel packaging suitable for automated assembly. TC4423EOE713 offers improved switching performance if high-frequency operation is required.

Q: Is TC4423COE suitable for all temperature ranges?

A: TC4423COE operates from 0°C to 150°C, compared to -40°C to 150°C for other substitutes. Selection of TC4423COE is appropriate only for applications with minimum operating temperatures at or above 0°C.

Q: What is the inventory status of substitute parts?

A: MIC4423YWM-TR: 1920 pcs. TC4423EOE: 2580 pcs. TC4423EOE713: 815 pcs. TC4423VOE: 916 pcs. TC4423VOE713: 1133 pcs. TC4423COE: 3300 pcs. All parts are new original stock.
