MIC4421YM-TR

Overview

The MIC4421YM-TR is a low-side MOSFET gate driver manufactured by Microchip Technology in an 8-SOIC package. It features non-inverting input logic with peak output currents of 9A source and sink. The device operates on a supply voltage range of 4.5V to 18V. Typical rise and fall times are 20ns and 24ns respectively, supporting high-speed switching applications for N-channel MOSFETs and IGBTs within a junction temperature range of -40°C to 150°C.

Feature Summary

Provides high-current drive capability for efficient power switching
Supports fast switching speeds with nanosecond transition times
Compatible with standard CMOS logic input levels

Applications

Low-side switching for N-channel MOSFETs
IGBT gate driving in power conversion circuits
DC-DC converter control stages

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the manufacturer part number matches exactly as MIC4421YM-TR to ensure correct pinout and electrical characteristics. Check datasheet revisions for any recent parameter updates or package changes before finalizing design integration.

Selection Notes

Select this component for applications requiring single-channel low-side drive with high peak current. Ensure the load capacitance and required switching speed align with the 20ns/24ns rise/fall time specifications. Verify that the input logic voltage levels remain within the specified VIL and VIH thresholds for reliable operation across the operating temperature range.

Part Context

This part belongs to the MIC4421/MIC4422 series of high-speed gate drivers. The MIC4421 variant specifically offers non-inverting logic, distinguishing it from the inverting MIC4422. Both share similar drive capabilities but differ in signal phase relationship relative to the input command.
