MIC4223YMME

Overview

The MIC4223YMME is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent channels designed to drive N-channel power MOSFETs with a peak output current of 4A for both sourcing and sinking. The device operates within a supply voltage range of 4.5V to 18V and supports logic input levels of 0.8V (low) and 2.4V (high). It provides an inverting input configuration with typical rise and fall times of 15ns. The component is rated for junction temperatures between -40°C and 125°C and is housed in an 8-MSOP package with an exposed pad.

Feature Summary

• Dual independent channel architecture for simultaneous low-side switching control
• High peak output current capability of 4A per channel for efficient MOSFET driving
• Fast switching performance with 15ns typical transition times
• Exposed pad thermal design for enhanced heat dissipation in compact packages

Applications

• Low-side switching in DC-DC converter topologies
• Motor control circuits requiring independent phase drive
• Power management systems utilizing N-channel MOSFET arrays

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure the ordering part number matches the required MSOP-EP variant. Cross-reference datasheet revisions to confirm pinout compatibility and electrical characteristics before integration into production designs.

Selection Notes

Select this component when dual independent low-side drive is required with high current capability. The 4A peak output ensures rapid charging and discharging of gate capacitances. Verify that the system supply voltage remains within the 4.5V to 18V operational range and that the logic interface aligns with the specified input thresholds.

Part Context

This device belongs to the MIC4223 series of gate drivers from Microchip Technology. It is functionally related to other variants such as the MIC4223YM, which shares similar electrical characteristics but utilizes an SOIC package instead of the MSOP form factor. The series is designed for applications requiring robust low-side switching performance.

Replacement Considerations

The MIC4223YM serves as a package-compatible alternative offering identical electrical specifications in an 8-SOIC footprint. Verify mechanical fitment and thermal requirements when substituting between MSOP-EP and SOIC packages.
