MIC4425BWM Equivalent & Substitute Parts

Part Overview

The MIC4425BWM is a low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in independent configurations. This device operates across a 4.5V to 18V supply range with dual inverting and non-inverting input channels, delivering 3A peak output current for both source and sink operations.

The MIC4425BWM is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this gate driver topology.

Substitute Part Grouping Explanation

Substitution eligibility for the MIC4425BWM is determined by strict electrical and mechanical parameter matching:

Core Substitution Criteria:

• Driven Configuration: Low-Side (required match)
• Number of Drivers: 2 (required match)
• Gate Type: N-Channel, P-Channel MOSFET (required match)
• Voltage - Supply: 4.5V ~ 18V (required match)
• Logic Voltage - VIL, VIH: 0.8V, 2.4V (required match)
• Current - Peak Output (Source, Sink): 3A, 3A (required match)
• Input Type: Inverting, Non-Inverting (required match)
• Operating Temperature: -40°C ~ 150°C (TJ) (required match)
• Package / Case: 16-SOIC (0.295", 7.50mm Width) (required match)
• Mounting Type: Surface Mount (required match)

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

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the MIC4425BWM within the specified parameter envelope. Selection should be based on the following factors:

Product Status and Availability: MIC4425YWM, TC4425EOE, TC4425EOE713, TC4425VOE, and TC4425VOE713 are all classified as Active products, ensuring ongoing availability and supply chain support compared to the obsolete MIC4425BWM.

Compliance Requirements: All substitute parts are ROHS3 compliant, whereas the MIC4425BWM is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, any of the listed substitutes satisfy regulatory obligations.

Moisture Sensitivity: TC4425EOE, TC4425EOE713, TC4425VOE, and TC4425VOE713 feature MSL 1 (Unlimited), providing superior moisture tolerance compared to MIC4425YWM (MSL 2, 1 Year). For long-term storage or high-humidity environments, MSL 1 rated parts are preferred.

Packaging Format: Tube packaging (MIC4425YWM, TC4425EOE, TC4425VOE) is suitable for manual assembly and lower-volume production. Tape & Reel format (TC4425EOE713, TC4425VOE713) is optimized for automated pick-and-place assembly and high-volume manufacturing.

Performance Characteristics: TC4425 series parts (TC4425EOE, TC4425EOE713, TC4425VOE, TC4425VOE713) exhibit improved rise/fall time performance (23ns, 25ns) compared to MIC4425BWM and MIC4425YWM (28ns, 32ns), resulting in faster switching transitions and reduced propagation delay.

Frequently Asked Questions (FAQ)

Q: Can MIC4425YWM be used as a direct replacement for MIC4425BWM?

A: Yes. MIC4425YWM maintains identical electrical specifications and package configuration. The primary differences are product status (Active vs. Obsolete), RoHS compliance (ROHS3 vs. non-compliant), and moisture sensitivity level (MSL 2 vs. MSL 1). Functional substitution is complete.

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 format, while TC4425EOE713 is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and volume considerations.

Q: Are TC4425VOE and TC4425VOE713 upgrades or direct substitutes?

A: TC4425VOE and TC4425VOE713 are functionally equivalent to MIC4425BWM and other listed substitutes. They are classified as upgrades due to improved rise/fall time performance (23ns, 25ns vs. 28ns, 32ns), which results in faster switching characteristics. All other electrical and mechanical parameters remain identical.

Q: Does the improved rise/fall time of TC4425 series parts affect circuit design?

A: Rise/fall time performance is determined by the device specifications provided. Faster switching transitions may reduce propagation delay in gate drive circuits. Circuit validation should be performed if switching speed is a critical design parameter.

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

A: For new designs, any Active product with ROHS3 compliance is appropriate. TC4425EOE, TC4425EOE713, TC4425VOE, or TC4425VOE713 are recommended due to active product status, full RoHS compliance, and MSL 1 moisture sensitivity. Packaging format selection (Tube vs. Tape & Reel) should align with manufacturing process requirements.

Q: Are all substitute parts pin-compatible with MIC4425BWM?

A: All substitute parts utilize the 16-SOIC package with identical pin configuration and electrical interface. Pin compatibility is confirmed across all listed substitutes.

Q: What is the inventory status of substitute parts?

A: Current inventory levels are: MIC4425YWM (855 Pcs), TC4425EOE (923 Pcs), TC4425EOE713 (682 Pcs), TC4425VOE (942 Pcs), TC4425VOE713 (1071 Pcs). Inventory status is subject to change and should be confirmed at time of procurement.
