MIC4469CWM Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The MIC4469CWM 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 1.2A peak output current (source and sink). The MIC4469CWM is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. Equivalent alternatives maintain identical electrical specifications and package form factor while offering improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MIC4469CWM is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side only
• Number of Drivers: 4 independent channels
• Gate Type: N-Channel and P-Channel MOSFET support
• Supply Voltage Range: 4.5V ~ 18V
• Peak Output Current: 1.2A source and sink capability
• Package Form Factor: 16-SOIC surface mount
• Input Logic Levels: VIL 0.8V, VIH 2.4V

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in rise/fall time (14ns–15ns typical) and operating temperature range do not affect functional substitution within the specified parameter set.

Engineering Selection Recommendations

MIC4469ZWM is the direct successor to MIC4469CWM from Microchip Technology. It maintains identical electrical performance and package specifications while offering active product status and ROHS3 compliance. This part is suitable for applications where the original MIC4469CWM is no longer available and RoHS compliance is required. MSL rating of 2 (1 Year) requires standard moisture control during storage and handling.

TC4469COE and TC4469COE713 are functionally equivalent alternatives from Microchip Technology's TC4469 product line. Both parts deliver the same electrical specifications and 16-SOIC package form factor. These parts feature extended operating temperature range (0°C ~ 150°C TJ) and MSL rating of 1 (Unlimited), providing enhanced thermal performance and simplified moisture management. TC4469COE is supplied in tube packaging, while TC4469COE713 is available in Cut Tape and Digi-Reel format for automated assembly processes.

Selection between MIC4469ZWM and TC4469 variants depends on packaging requirements, inventory availability, and thermal operating conditions. All three substitute parts are ROHS3 compliant and suitable for direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can MIC4469ZWM directly replace MIC4469CWM in existing designs?

A: Yes. MIC4469ZWM maintains identical electrical specifications, logic levels, output current ratings, and 16-SOIC package dimensions. Pin-for-pin compatibility is confirmed across all functional parameters.

Q: What is the difference between MIC4469ZWM and TC4469COE?

A: Both parts are functionally equivalent low-side gate drivers with identical supply voltage, output current, and package specifications. TC4469COE offers extended operating temperature range (0°C ~ 150°C TJ versus 0°C ~ 70°C TA) and unlimited moisture sensitivity level. MIC4469ZWM is the direct Microchip successor to the obsolete MIC4469CWM.

Q: Are there packaging differences between substitute parts?

A: Yes. MIC4469ZWM and TC4469COE are supplied in tube packaging. TC4469COE713 is available in Cut Tape and Digi-Reel format, optimized for high-volume automated assembly. All three maintain identical 16-SOIC package dimensions.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. MIC4469ZWM, TC4469COE, and TC4469COE713 are all ROHS3 compliant. The original MIC4469CWM is RoHS non-compliant.

Q: What is the moisture sensitivity level (MSL) requirement for each part?

A: MIC4469ZWM has MSL 2 (1 Year), requiring standard moisture control during storage. TC4469COE and TC4469COE713 have MSL 1 (Unlimited), allowing extended shelf life without special moisture management.

Q: Can TC4469 variants be used in applications requiring the original 0°C ~ 70°C operating temperature range?

A: Yes. TC4469COE and TC4469COE713 are rated to 0°C ~ 150°C (TJ), which encompasses the original 0°C ~ 70°C specification. Extended temperature rating does not affect operation within the lower temperature range.
