MIC4425YN

Overview

The MIC4425YN is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features a peak output current of 3 A and operates within a supply voltage range of 4.5 V to 18 V. The device provides both inverting and non-inverting outputs, packaged in an 8-pin DIP configuration. It utilizes a BiCMOS/DMOS process for high reliability and noise immunity.

Feature Summary

• Dual channel architecture with complementary inverting and non-inverting outputs
• High peak output current capability of 3 A for rapid MOSFET switching
• Robust noise immunity capable of surviving ground pin spiking

Applications

• Low-side power switching applications
• Motor control circuits
• DC-DC converter gate driving

Procurement Notes

Verify the specific package variant, as the MIC4425 series includes SOIC and DIP options. Confirm RoHS compliance status for the specific revision, as some sources indicate non-compliance while others suggest lead-free variants exist. Check current availability as distribution may vary by region.

Selection Notes

Select this component when a dual low-side driver with moderate 3 A drive strength is required. Ensure the application does not exceed the 18 V maximum supply rating. Consider the PDIP-8 package constraints for thermal management and board space compared to surface-mount alternatives.

Part Context
