MIC4415YFT-TR

Overview

The MIC4415YFT-TR is a low-side MOSFET gate driver manufactured by Microchip Technology, designed to switch N-channel enhancement type MOSFETs in low-side applications. It features an inverting input configuration and operates within a supply voltage range of 4.5V to 18V. The device delivers peak output currents of 1.5A for both sourcing and sinking. It achieves typical rise and fall times of 12ns into a 1000pF load. The component is housed in a 4-TQFN package measuring 1.2mm x 1.2mm and is rated for junction temperatures from -40°C to +125°C.

Feature Summary

• Inverting logic input configuration for precise edge control
• High peak current capability of 1.5A for rapid switching
• Ultra-small 4-pin QFN package design for compact layouts
• Wide operating supply voltage range supporting standard and logic-level MOSFETs

Applications

• Low-side switching applications for N-channel MOSFETs
• Compact isolated power supplies
• General-purpose motor control circuits
• DC-DC converter gate drive stages

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm that the inverting function matches the circuit design requirements, as the non-inverting variant exists. Check current availability status as some distributors may list discontinued or out-of-stock statuses for this specific part number. Ensure the 4-TQFN footprint matches the PCB layout constraints.

Selection Notes

Select this component when an inverting signal path is required for low-side drive. Consider the 1.5A peak current limit for driving capacitive loads. Evaluate the 4.5V minimum supply voltage against the logic level of the controlling microcontroller. The small package size makes it suitable for space-constrained designs compared to larger SOIC packages.

Part Context

This part belongs to the MIC4414/MIC4415 family of low-side drivers. The MIC4414 is the non-inverting counterpart, while the MIC4415 provides the inverting function. Both share similar electrical characteristics and package options, differing primarily in input logic polarity. They are designed for high-speed switching applications requiring fast rise and fall times.

Replacement Considerations

MIC4415YFT-T5 is a listed substitute with identical electrical specifications but potentially different packaging or lot codes. Verify pinout compatibility before substitution. Other generic low-side drivers may require external components to match the 1.5A peak current and 12ns timing performance.
