MIC4126YMME-TR

Overview

The MIC4126YMME-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features a peak output current of 1.5A and operates with supply voltages up to 30V. The device utilizes an MSOP-8 package with exposed pad for thermal management. Key electrical parameters include a rise time of 20ns and fall time of 18ns. Logic thresholds are defined at 0.8V for low-level input and 2.4V for high-level input. It is designed for driving N-channel MOSFETs in non-inverting configurations.

Feature Summary

• Dual channel architecture providing independent control for two low-side MOSFETs
• High-speed switching capability with nanosecond rise and fall times
• Low thermal impedance design facilitated by exposed pad packaging
• Compatible with standard logic voltage levels for direct microcontroller interfacing

Applications

• DC-DC converter circuits requiring efficient low-side switching
• Motor drive systems utilizing N-channel MOSFET power stages
• Inverter topologies needing isolated or non-isolated gate drive signals

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging containing 2500 units. Confirm the MSOP-8EP package type matches your PCB footprint requirements. Ensure the component is RoHS compliant as per manufacturer specifications. Cross-reference the datasheet revision date to guarantee parameter accuracy for your design implementation.

Selection Notes

Select this component when dual low-side drive is required with moderate current capabilities. The 1.5A peak current suits small to medium power MOSFETs. Consider the MSOP-8EP package for space-constrained designs requiring improved heat dissipation compared to standard SOIC packages. Verify input logic compatibility with your system's voltage levels before integration.

Part Context

This part belongs to the MIC4126 series of dual low-side MOSFET drivers from Microchip Technology. It shares functional similarities with other members like the MIC4124 and MIC4128 but differs in specific current ratings and package options. The YMME variant specifically denotes the MSOP-8EP package configuration, distinguishing it from other pinout or thermal performance variations within the broader family.

Replacement Considerations

Direct substitutes may include the MIC4126YMME without the trailing TR if loose tube packaging is acceptable. Other compatible devices in the same family should be evaluated based on identical pinouts and electrical characteristics. Always verify that alternative parts meet the specific 1.5A peak current and 30V supply voltage requirements.
