MIC4452YM

Overview

The MIC4452YM is a low-side MOSFET gate driver manufactured by Microchip Technology. It features a non-inverting configuration with a single driver and output channel. The device operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 12 A. Electrical characteristics include rise and fall times of 25 ns, with maximum on/off delays of 80 ns. It functions in temperatures from -40°C to +125°C, consumes 450 µA operating current, and dissipates up to 1.04 W power. The component is housed in an 8-SOIC package.

Feature Summary

• Provides high peak output current capability for driving large capacitive loads
• Features fast switching speeds with 25 ns rise and fall times
• Operates with a wide supply voltage range suitable for various logic levels

Applications

• Motor control systems requiring high-speed switching
• Power supply circuits utilizing low-side MOSFETs
• High-frequency inverter applications

Procurement Notes

Verify the specific suffix 'YM' corresponds to the SOIC-8 package and industrial temperature range (-40°C to +125°C). Confirm RoHS compliance status through official documentation. Ensure moisture sensitivity handling protocols are followed during storage and assembly. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select this component when a non-inverting low-side driver with 12 A peak current is required. It is suitable for applications needing fast switching transitions under 25 ns. Consider the 8-SOIC package constraints for PCB layout. Verify that the input logic levels are compatible with the CMOS technology used in this driver circuit design.

Part Context

This component belongs to the MIC4451/MIC4452 series of high-performance gate drivers. The MIC4452 variant specifically offers a non-inverting output, distinguishing it from the inverting MIC4451. Both share similar electrical specifications but differ in signal phase relationship. The series is designed for robust performance in demanding power electronics environments.

Replacement Considerations

The MIC4451YM serves as a functional substitute if an inverting configuration is acceptable. Other low-side drivers with comparable 12 A current ratings and SOIC-8 packaging may be considered after verifying pinout compatibility and electrical parameter alignment.
