MIC4126YML-TR

Overview

The MIC4126YML-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent inverting channels with peak output currents of 1.5A 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 (VIL) and 2.4V (VIH). Typical rise and fall times are 20ns and 29ns, respectively. It is housed in an 8-MLF package measuring 2x2mm and functions across a junction temperature range of -40°C to 150°C.

Feature Summary

• Dual independent low-side driving configuration for N-channel and P-channel MOSFETs
• High-speed switching capability with low thermal impedance packaging
• Inverting logic input type compatible with standard digital interfaces

Applications

• DC-DC converter synchronous rectification control
• Motor drive bridge circuits
• Power supply output stage management

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging containing 5000 units. Confirm the MLF-8 package variant matches the design footprint requirements. Check RoHS compliance status as per current manufacturer declarations. Ensure the operating temperature range aligns with the target application environment constraints before finalizing procurement.

Selection Notes

Select this component when dual isolated low-side driving is required in a compact form factor. The 1.5A peak current suits medium-power MOSFET applications. Consider the 8-MLF package for space-constrained PCB layouts. Verify that the inverting logic polarity fits the system control scheme without additional inversion hardware.

Part Context

This part belongs to the MIC4126 family of high-speed MOSFET drivers. It shares functional similarities with the MIC4426 series but utilizes advanced packaging technology for improved thermal performance. The device is designed to replace older generation drivers offering similar current capabilities in smaller footprints.

Replacement Considerations

Direct substitutes include other dual low-side drivers from Microchip such as the MIC4426YM-TR, though package differences must be accounted for. Cross-vendor replacements require verification of pin compatibility and electrical specifications.
