MIC4225YMME-TR

Overview

The MIC4225YMME-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent channels with inverting and non-inverting outputs, delivering a peak output current of 4A per channel. The device operates within a supply voltage range of 4.5V to 18V. Key switching characteristics include rise and fall times of 15ns each. It is housed in an 8-pin MSOP package with an exposed pad for thermal management.

Feature Summary

• Dual independent low-side driver configuration supporting simultaneous control of two external MOSFETs
• Integrated inverting and non-inverting output options for flexible logic interface compatibility
• High-speed switching performance with 15ns rise and fall times for efficient power conversion
• Robust 4A peak output current capability to drive low-resistance MOSFET gates effectively

Applications

• DC-DC converter circuits requiring isolated or non-isolated low-side switching
• Motor control systems utilizing low-side N-channel MOSFET arrangements
• Power supply designs needing fast-switching gate drive signals for efficiency optimization

Procurement Notes

Verify the exact suffix 'YMME' corresponds to the MSOP-8 package with exposed pad as specified in the official Microchip datasheet. Confirm RoHS compliance status through the manufacturer's latest documentation. Ensure ordering quantities match tape-and-reel specifications provided in the procurement data sheet to avoid packaging discrepancies during assembly.

Selection Notes

Select this component when dual low-side driving with mixed polarity inputs is required. The 4A current rating suits moderate-power applications where rapid MOSFET turn-on/off is critical. Consider the 15ns switching speed for high-frequency operations up to typical DC-DC converter ranges. Evaluate thermal requirements due to the exposed pad design for heat dissipation in dense PCB layouts.

Part Context

This part belongs to the MIC422x family of dual low-side MOSFET drivers from Microchip Technology (formerly Micrel). The family includes variants like MIC4223 and MIC4224, differing primarily in input configurations. The MIC4225 specifically offers one inverting and one non-inverting channel, providing versatility compared to fully inverting or non-inverting counterparts in the same series.

Replacement Considerations

Direct substitutes within the same family include MIC4223YMME-TR and MIC4224YMME-TR, though input logic polarities differ. Verify pinout compatibility and electrical parameters such as supply voltage range and output current before substitution. Cross-reference with other manufacturers' dual low-side drivers only if functional equivalence is confirmed via detailed datasheet comparison.
