MIC4223YMME-TR

Overview

The MIC4223YMME-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features an inverting logic configuration with independent channels designed for N-channel power MOSFETs. The device operates within a supply voltage range of 4.5V to 18V and supports input logic levels defined by VIL at 0.8V and VIH at 2.4V. It delivers a peak output current of 4A for both sourcing and sinking capabilities. Typical rise and fall times are specified at 15ns under a 2000pF load condition. The component is housed in an 8-pin MSOP package with an exposed pad (MSOP-EP) and is rated for operation across a junction temperature range of -40°C to +125°C.

Feature Summary

• Dual independent channel architecture for driving two low-side N-channel MOSFETs simultaneously
• High-speed switching performance with typical 15ns rise and fall times
• Robust drive capability providing 4A peak source and sink currents
• Integrated enable functionality for precise control of driver states

Applications

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

Procurement Notes

Verify the specific suffix 'YMME-TR' to confirm the 8-MSOP-EP package type and tape-and-reel packaging format. Ensure compatibility with the required inverting logic interface, as non-inverting variants exist within the same family. Confirm that the PCB footprint accommodates the exposed thermal pad for adequate heat dissipation during high-current operation. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or pinout configurations.

Selection Notes

Select this component when dual low-side drive with inverting logic is required. The 4A peak current rating suits moderate-power applications, while the 15ns switching speed supports higher frequency operations. Consider the exposed pad package for improved thermal performance compared to standard SOIC packages. Verify that the system's logic voltage levels align with the specified 0.8V/2.4V thresholds to ensure reliable signal interpretation without additional level shifting.

Part Context

This part belongs to the MIC4223 series of high-speed MOSFET drivers from Microchip Technology. It is functionally related to the MIC4224 series, which offers non-inverting logic instead of the inverting configuration found in the MIC4223. Both series share similar electrical characteristics regarding supply voltage and drive current but differ in signal polarity. The YMME-TR designation specifically identifies the MSOP-EP package variant supplied in tape and reel.

Replacement Considerations

• MIC4224YMME-TR: Non-inverting equivalent with identical package and electrical specs
• MIC4223YM-TR: Inverting equivalent in 8-SOIC package without exposed pad
• MIC4223YMME: Non-tape-and-reel version in 8-MSOP-EP package
