MIC4452YN

Overview

The MIC4452YN is a single-channel, low-side MOSFET gate driver manufactured by Microchip Technology. It features a non-inverting logic configuration and delivers a peak output current of 12A. The device operates within a supply voltage range of 4.5V to 18V. Key electrical characteristics include rise and fall times of 25ns each, supporting switching frequencies up to 2MHz. It is housed in an 8-pin PDIP package.

Feature Summary

• Delivers high peak output current for driving large MOSFETs
• Provides fast propagation delay and switching speeds
• Features robust CMOS construction for reliable operation

Applications

• Line drivers
• Local power on/off switches
• High-speed MOSFET gate drive circuits

Procurement Notes

Verify the specific suffix 'YN' corresponds to the 8-pin PDIP package and industrial temperature range when sourcing. Confirm that the component is sourced from authorized Microchip distributors to ensure authenticity. Check for any updated datasheet revisions that may affect pinout or electrical specifications compared to legacy Micrel versions.

Selection Notes

Select this component when a single-channel, non-inverting driver with high peak current capability is required. Ensure the application voltage stays within the 4.5V to 18V range. Consider the 25ns transition times for high-frequency applications. Verify that the PDIP package fits the PCB layout constraints.

Part Context

This part belongs to the MIC4452 family of high-speed MOSFET drivers. It is functionally similar to other variants like the MIC4452YM (SOIC-8) but differs in package type. The series is designed to improve safe operating margins for power MOSFETs by providing strong drive currents.

Replacement Considerations

The MIC4452YM is a direct functional substitute with identical electrical specifications but uses an SOIC-8 package instead of PDIP. Cross-reference with other single-channel low-side drivers if package compatibility allows.
