MIC4414YFT-TR

Overview

The MIC4414YFT-TR is a low-side single non-inverting MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.5V to 18V and supports output currents up to 1.5A. The device is housed in a compact 4-pin Thin QFN (1.2 x 1.2 mm) package, designated as UDFN. It functions with input voltages up to 18V and maintains performance across an extended temperature range from -40°C to +125°C.

Feature Summary

• Ultra-small physical footprint utilizing a 4-pin Thin QFN package for space-constrained designs
• High peak output current capability of 1.5A for efficient MOSFET switching
• Wide operating supply voltage range accommodating 4.5V to 18V systems

Applications

• Low-side MOSFET driving in DC-DC converter topologies
• Motor control applications requiring small form factor drivers
• General purpose power management circuits needing high-speed switching

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the 4-pin UDFN package dimensions match your PCB layout requirements. Ensure the operating environment stays within the specified -40°C to +125°C temperature range for reliable performance. Cross-reference the datasheet for exact pinout configurations before integration.

Selection Notes

Select this component when a minimal board area is critical due to its 1.2 x 1.2 mm package size. It is suitable for applications requiring a single low-side driver with moderate current demands up to 1.5A. Consider the 4.5V to 18V supply range compatibility with your system's logic levels. Evaluate thermal dissipation needs given the small package surface area.

Part Context

This part belongs to Microchip's family of ultra-small low-side MOSFET drivers. It shares functional similarities with other devices in the series but is distinguished by its specific 4-pin configuration and current rating. The product line focuses on providing robust gate driving capabilities in minimal footprints for modern portable and industrial electronics.

Replacement Considerations

Check for direct substitutes within the same Microchip low-side driver family that offer compatible pinouts and electrical characteristics. Verify that any alternative component matches the 1.5A output current and 4.5V-18V supply range specifications.
