MIC4425CWM TR Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The MIC4425CWM TR 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 component operates across a 4.5V to 18V supply voltage range and delivers 3A peak output current for both source and sink operations. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts maintain identical electrical specifications and mechanical compatibility while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC4425CWM TR is determined by strict adherence to the following electrical and mechanical parameters:

Critical Substitution Parameters:

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

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

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Electrical Performance): MIC4425ZWM-TR is the primary direct replacement for MIC4425CWM TR. Both parts maintain identical rise/fall time specifications (28ns, 32ns) and operating temperature range (0°C ~ 150°C). MIC4425ZWM-TR offers active product status and ROHS3 compliance, addressing the obsolescence and regulatory concerns of the original part.

Functional Equivalents (Enhanced Performance): TC4425 series parts (TC4425COE, TC4425COE713, TC4425EOE, TC4425EOE713, TC4425VOE, TC4425VOE713) provide functional equivalence with improved switching performance. These parts deliver faster rise/fall times (23ns, 25ns) while maintaining identical supply voltage, output current, and input configuration specifications. All TC4425 variants are ROHS3 compliant and carry active product status.

Temperature Range Considerations: TC4425EOE, TC4425EOE713, TC4425VOE, and TC4425VOE713 extend the operating temperature range to -40°C ~ 150°C, providing enhanced low-temperature performance compared to the original 0°C ~ 150°C specification.

Packaging Format Selection: Tape & Reel (TR) packaging is available in MIC4425ZWM-TR, TC4425COE713, TC4425EOE713, and TC4425VOE713 for automated assembly operations. Tube packaging is available in TC4425COE, TC4425EOE, and TC4425VOE for manual handling or lower-volume applications.

Frequently Asked Questions (FAQ)

Q: Can TC4425 series parts directly replace MIC4425CWM TR? A: Yes. TC4425 series parts maintain all critical electrical parameters: 4.5V ~ 18V supply voltage, 3A peak output current (source and sink), inverting/non-inverting input configuration, and 16-SOIC package format. The faster switching performance (23ns/25ns vs. 28ns/32ns) represents an improvement that does not compromise compatibility.

Q: What is the difference between MIC4425ZWM-TR and TC4425 variants? A: MIC4425ZWM-TR maintains the original switching speed (28ns/32ns) and operating temperature range (0°C ~ 150°C). TC4425 variants offer faster switching (23ns/25ns) and extended temperature range options (-40°C ~ 150°C for EOE and VOE variants). Both families are electrically compatible substitutes.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR) and Tube packaging formats contain identical die and electrical specifications. Selection depends on assembly process requirements and handling procedures, not functional performance.

Q: Are all substitute parts ROHS3 compliant? A: All substitute parts listed are ROHS3 compliant. The original MIC4425CWM TR is RoHS non-compliant. Substitution with any listed part addresses regulatory compliance requirements.

Q: What inventory levels are available for each substitute? A: MIC4425ZWM-TR: 814 Pcs; TC4425COE: 2330 Pcs; TC4425COE713: 952 Pcs; TC4425EOE: 923 Pcs; TC4425EOE713: 682 Pcs; TC4425VOE: 942 Pcs; TC4425VOE713: 1071 Pcs.

Q: Can I use TC4425EOE or TC4425VOE in applications requiring 0°C minimum operating temperature? A: TC4425EOE and TC4425VOE are rated for -40°C ~ 150°C operation. They function correctly at 0°C and above, making them suitable for applications with 0°C minimum temperature requirements.
