MIC4425BWM TR Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The MIC4425BWM TR is a low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in independent dual-channel configurations. This component operates across a 4.5V to 18V supply voltage range with inverting and non-inverting input types, making it suitable for power management applications requiring precise gate control.

The MIC4425BWM TR is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and access components with improved compliance certifications or performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC4425BWM TR is determined by the following critical parameters:

• Driven Configuration: Must be Low-Side
• Number of Drivers: Must be 2 (dual-channel independent)
• Gate Type: Must support N-Channel and P-Channel MOSFET driving
• Voltage - Supply: Must operate within 4.5V ~ 18V range
• Current - Peak Output: Must provide 3A source and 3A sink capability
• Input Type: Must support both Inverting and Non-Inverting configurations
• Package / Case: Must be 16-SOIC form factor
• Mounting Type: Must be Surface Mount

All identified substitute parts meet these core electrical and mechanical requirements. Variations in rise/fall time performance, packaging format (Tube vs. Tape & Reel), and compliance certifications are secondary considerations that do not affect functional interchangeability within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

MIC4425YWM-TR is the direct successor to MIC4425BWM TR within the Microchip MIC4425 product line. Both parts maintain identical electrical specifications and 16-SOIC packaging. MIC4425YWM-TR is currently in active production status and carries ROHS3 compliance certification, addressing regulatory requirements that the obsolete MIC4425BWM TR does not meet. This part is recommended for designs requiring minimal qualification effort and direct form-factor compatibility.

TC4425EOE and TC4425EOE713 represent the TC4425 product family from Microchip Technology. These parts deliver improved switching performance with reduced rise and fall times (23ns, 25ns versus 28ns, 32ns). Both variants are ROHS3 compliant and active in production. TC4425EOE713 is supplied in Tape & Reel packaging, matching the original MIC4425BWM TR format. TC4425EOE is supplied in Tube packaging, suitable for lower-volume applications.

TC4425VOE and TC4425VOE713 are upgrade variants within the TC4425 family, offering the same performance improvements as the EOE variants with identical electrical and thermal specifications. TC4425VOE713 maintains Tape & Reel packaging compatibility with the original part.

All substitute parts are manufactured by Microchip Technology, ensuring consistent quality standards and technical support. Selection between MIC4425YWM-TR and TC4425 variants depends on packaging requirements and performance optimization priorities. All identified substitutes are ROHS3 compliant and suitable for modern supply chain integration.

Frequently Asked Questions (FAQ)

Q: Can MIC4425YWM-TR directly replace MIC4425BWM TR without design changes?

A: Yes. MIC4425YWM-TR maintains identical electrical specifications, pin configuration, and 16-SOIC package dimensions. No circuit modifications are required for functional substitution.

Q: What is the difference between TC4425EOE and TC4425EOE713?

A: Both parts are electrically identical. The primary difference is packaging format: TC4425EOE is supplied in Tube packaging, while TC4425EOE713 is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and volume considerations.

Q: Are TC4425 variants compatible with designs using MIC4425BWM TR?

A: Yes. TC4425 variants meet all core electrical and mechanical substitution criteria. The improved rise and fall time performance (23ns, 25ns versus 28ns, 32ns) represents a performance enhancement that does not compromise backward compatibility. Pin configuration and package form factor remain consistent.

Q: What is the significance of the "713" suffix in part numbers like TC4425EOE713?

A: The "713" suffix indicates Tape & Reel packaging format, suitable for automated assembly processes. Parts without this suffix (TC4425EOE, TC4425VOE) are supplied in Tube packaging for manual or lower-volume assembly operations.

Q: Does the MSL (Moisture Sensitivity Level) difference affect component selection?

A: MSL ratings indicate moisture sensitivity during storage and handling. MIC4425YWM-TR carries MSL 2 (1 Year), while TC4425 variants carry MSL 1 (Unlimited). MSL 1 provides extended shelf life without moisture-controlled storage requirements, offering supply chain advantages for long-term inventory management.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification. The original MIC4425BWM TR is RoHS non-compliant. Substitution with any identified alternative ensures regulatory compliance for modern applications and markets with RoHS requirements.

Q: What is the inventory status of these substitute parts?

A: All substitute parts are currently in active production with confirmed stock availability: MIC4425YWM-TR (844 Pcs), TC4425EOE (923 Pcs), TC4425EOE713 (682 Pcs), TC4425VOE (942 Pcs), and TC4425VOE713 (1071 Pcs).
