MIC4224YM-TR

Overview

The MIC4224YM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features non-inverting inputs and delivers a peak output current of 4A for both sourcing and sinking. The device operates within a supply voltage range of 4.5V to 18V and supports logic input thresholds of 0.8V (VIL) and 2.4V (VIH). Typical rise and fall times are 15ns each. It is housed in an 8-SOIC package with a wide operating junction temperature range.

Feature Summary

• Dual independent low-side channel configuration
• Non-inverting input logic compatibility
• High peak output drive capability

Applications

• DC-DC converter control circuits
• Motor driver bridge stages
• Power supply switching regulation

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the 8-SOIC package dimensions match the PCB footprint requirements. Ensure the supply voltage does not exceed the 18V maximum rating during operation. Check for RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component for applications requiring fast switching speeds with moderate drive current. The non-inverting configuration simplifies control logic integration compared to inverting alternatives. Consider the thermal performance of the SOIC package for high-duty cycle operations. Verify that the load capacitance remains within limits to maintain the specified 15ns transition times.

Part Context

This part belongs to the MIC422x series of low-side gate drivers from Microchip. It shares functional similarities with the MIC4223 but differs in input inversion polarity. The series is designed for driving N-channel MOSFETs in compact power management solutions. The YM variant specifically denotes the MSOP or SOIC package options available within this product line.

Replacement Considerations

The MIC4223YM-TR serves as a direct pin-compatible alternative, though it features inverting inputs rather than non-inverting ones. Designers must account for this logical difference when substituting components to ensure correct signal timing and phase relationships in the circuit.
