MIC4425CWM Equivalent & Substitute Parts

Part Overview

The MIC4425CWM is a low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in independent configurations. This component operates with a supply voltage range of 4.5V to 18V and delivers peak output currents of 3A (source and sink). The MIC4425CWM is classified as obsolete, which necessitates identification of active equivalent and substitute parts for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC4425CWM is determined by the following critical parameters:

• Driven Configuration: Low-Side (all substitutes maintain this specification)
• Number of Drivers: 2 independent channels (all substitutes maintain this specification)
• Gate Type: N-Channel, P-Channel MOSFET support (all substitutes maintain this specification)
• Voltage - Supply: 4.5V ~ 18V (all substitutes maintain this specification)
• Logic Voltage - VIL, VIH: 0.8V, 2.4V (all substitutes maintain this specification)
• Current - Peak Output: 3A source and sink (all substitutes maintain this specification)
• Package / Case: 16-SOIC form factor (all substitutes maintain this specification)
• Mounting Type: Surface Mount (all substitutes maintain this specification)

Substitute parts are grouped into two categories: direct equivalents (MIC4425ZWM, TC4425COE, TC4425COE713) and upgraded variants (TC4425EOE, TC4425EOE713, TC4425VOE, TC4425VOE713). Direct equivalents maintain identical electrical specifications. Upgraded variants extend the operating temperature range to -40°C ~ 150°C and offer improved rise/fall time performance (23ns/25ns versus 28ns/32ns).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended for Pin-Compatible Replacement): MIC4425ZWM is the direct active equivalent to MIC4425CWM. Both parts maintain identical electrical specifications and 16-SOIC packaging. MIC4425ZWM achieves ROHS3 compliance, addressing regulatory requirements of the obsolete MIC4425CWM. This part is suitable for direct substitution in existing designs without circuit modification.

Direct Equivalent with Improved Performance: TC4425COE and TC4425COE713 provide improved rise/fall time performance (23ns/25ns) while maintaining the 0°C ~ 150°C operating temperature range. These parts are functionally compatible with MIC4425CWM and offer ROHS3 compliance. TC4425COE is supplied in Tube packaging; TC4425COE713 is supplied in Tape & Reel format for automated assembly.

Upgraded Variants with Extended Temperature Range: TC4425EOE, TC4425EOE713, TC4425VOE, and TC4425VOE713 extend the operating temperature range to -40°C ~ 150°C and deliver improved rise/fall time performance (23ns/25ns). These parts are suitable for applications requiring enhanced low-temperature operation. TC4425EOE and TC4425VOE are supplied in Tube packaging; TC4425EOE713 and TC4425VOE713 are supplied in Tape & Reel format.

Compliance Considerations: All substitute parts achieve ROHS3 compliance, addressing environmental and regulatory requirements. The MIC4425CWM is RoHS non-compliant; migration to any active substitute ensures compliance with current standards.

Frequently Asked Questions (FAQ)

Q: Can MIC4425ZWM directly replace MIC4425CWM in existing designs? A: Yes. MIC4425ZWM maintains identical electrical specifications, package form factor, and pin configuration. No circuit modifications are required. The primary difference is improved RoHS compliance status.

Q: What is the difference between TC4425COE and TC4425EOE? A: Both parts deliver identical rise/fall time performance (23ns/25ns) and peak output current (3A). The primary difference is operating temperature range: TC4425COE operates from 0°C ~ 150°C, while TC4425EOE extends to -40°C ~ 150°C. Select TC4425EOE for applications requiring low-temperature operation.

Q: What packaging options are available for TC4425 variants? A: TC4425 parts are available in two packaging formats: Tube (standard packaging for manual assembly) and Tape & Reel (TR) format for automated pick-and-place assembly. Part numbers ending in "713" indicate Tape & Reel packaging.

Q: Are all substitute parts RoHS compliant? A: Yes. All active substitute parts (MIC4425ZWM, TC4425COE, TC4425COE713, TC4425EOE, TC4425EOE713, TC4425VOE, TC4425VOE713) achieve ROHS3 compliance. The original MIC4425CWM is RoHS non-compliant.

Q: What is the difference between MIC4425ZWM and TC4425 series parts? A: MIC4425ZWM maintains the original MIC4425 base product specifications with improved compliance. TC4425 series parts offer improved rise/fall time performance (23ns/25ns versus 28ns/32ns) and extended temperature range options. Both families are functionally compatible for low-side gate driver applications.

Q: Which substitute part should I select for new designs? A: For new designs requiring standard temperature operation (0°C ~ 150°C), select TC4425COE or TC4425COE713. For applications requiring extended low-temperature operation (-40°C ~ 150°C), select TC4425EOE, TC4425EOE713, TC4425VOE, or TC4425VOE713. All parts provide improved performance and full RoHS compliance.
