MIC4423CWM Equivalent & Substitute Parts

Part Overview

The MIC4423CWM is a low-side gate driver IC manufactured by Microchip Technology, designed to drive N-Channel and P-Channel MOSFETs in independent channel configurations. This 16-SOIC package device operates across a 4.5V to 18V supply range with inverting input logic and dual independent driver channels.

The MIC4423CWM 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.

Substitute Part Grouping Explanation

Substitution for the MIC4423CWM is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side (all substitutes match)
• Number of Drivers: 2 independent channels (all substitutes match)
• Gate Type: N-Channel, P-Channel MOSFET (all substitutes match)
• Voltage - Supply: 4.5V ~ 18V (all substitutes match)
• Current - Peak Output: 3A source, 3A sink (all substitutes match)
• Input Type: Inverting (all substitutes match)
• Package / Case: 16-SOIC (0.295", 7.50mm Width) (all substitutes match)
• Logic Voltage - VIL, VIH: 0.8V, 2.4V (all substitutes match)

Substitute parts are grouped into two categories:

Direct Substitutes (MIC4423ZWM, TC4423COE, TC4423COE713): Functionally equivalent with identical electrical specifications. These parts maintain the same rise/fall time performance (28ns/32ns for MIC4423ZWM; 23ns/25ns for TC4423 variants) and operating temperature range (0°C ~ 150°C).

Upgrade Substitutes (TC4423EOE, TC4423EOE713, TC4423VOE, TC4423VOE713): Enhanced variants offering extended operating temperature range (-40°C ~ 150°C) and improved rise/fall time performance (23ns/25ns). All upgrade substitutes maintain electrical equivalence while providing superior thermal performance.

Engineering Selection Recommendations

For Direct Replacement (Minimum Change): Select MIC4423ZWM when maintaining the Microchip MIC4423 base product line is preferred. This part is active, ROHS3 compliant, and maintains identical electrical performance to the MIC4423CWM. Packaging is available in Tube format.

For Compliance Upgrade: Select TC4423COE or TC4423COE713 when transitioning to the TC4423 base product line with ROHS3 compliance is acceptable. These parts offer improved rise/fall time performance (23ns/25ns versus 28ns/32ns) while maintaining the standard 0°C to 150°C operating temperature range. TC4423COE713 is available in Tape & Reel packaging for high-volume applications.

For Extended Temperature Range Applications: Select TC4423EOE, TC4423EOE713, TC4423VOE, or TC4423VOE713 when designs require operation at temperatures below 0°C. All four variants extend the operating temperature range to -40°C ~ 150°C and deliver improved switching performance (23ns/25ns rise/fall times). TC4423EOE and TC4423VOE are available in Tube packaging; TC4423EOE713 and TC4423VOE713 are available in Tape & Reel packaging.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, supporting modern supply chain and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can MIC4423ZWM directly replace MIC4423CWM in existing designs? A: Yes. MIC4423ZWM is electrically equivalent with identical supply voltage range (4.5V ~ 18V), peak output current (3A source/sink), logic thresholds (0.8V/2.4V), and package footprint (16-SOIC). The primary differences are product status (Active versus Obsolete) and RoHS compliance (ROHS3 Compliant versus non-compliant).

Q: What is the difference between TC4423COE and TC4423EOE? A: Both parts are functionally equivalent with identical electrical specifications and 16-SOIC packaging. The key difference is operating temperature range: TC4423COE operates 0°C ~ 150°C, while TC4423EOE extends to -40°C ~ 150°C. Select TC4423EOE for applications requiring low-temperature operation.

Q: Does packaging format affect electrical performance? A: No. Tube and Tape & Reel (TR) packaging formats contain identical die and electrical specifications. Packaging selection is determined by assembly process requirements and volume. TC4423COE (Tube) and TC4423COE713 (Tape & Reel) are electrically identical.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed (MIC4423ZWM, TC4423COE, TC4423COE713, TC4423EOE, TC4423EOE713, TC4423VOE, TC4423VOE713) are ROHS3 compliant. The original MIC4423CWM is RoHS non-compliant.

Q: What is the significance of improved rise/fall times in TC4423 variants? A: TC4423 variants deliver 23ns/25ns rise/fall times compared to 28ns/32ns in MIC4423CWM and MIC4423ZWM. Faster switching transitions reduce gate charge delay and improve MOSFET switching efficiency, particularly beneficial in high-frequency switching applications.

Q: Can I use TC4423VOE as a substitute for TC4423EOE? A: Yes. TC4423VOE and TC4423EOE are electrically identical with matching specifications, operating temperature range (-40°C ~ 150°C), and rise/fall time performance (23ns/25ns). Selection between them depends on packaging preference (Tube versus Tape & Reel) and inventory availability.

Q: What is the Moisture Sensitivity Level (MSL) impact? A: MIC4423CWM, TC4423COE, TC4423COE713, TC4423EOE, TC4423EOE713, TC4423VOE, and TC4423VOE713 all carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. MIC4423ZWM carries MSL 2 (1 Year), requiring storage in controlled humidity conditions for one year from manufacturing date.
