MIC4423YWM-TR

Overview

The MIC4423YWM-TR is a low-side MOSFET gate driver manufactured by Microchip Technology. It features a dual-channel inverting configuration housed in a 16-SOIC package. The device delivers a peak output current of 3A for both sourcing and sinking operations. It operates within a supply voltage range of 4.5V to 18V. Typical switching characteristics include a rise time of 28ns and a fall time of 32ns. The component supports junction temperatures up to 150°C and includes latch-up protection exceeding 500mA reverse current.

Feature Summary

• High peak output current capability of 3A for efficient MOSFET and IGBT switching
• Robust BiCMOS/DMOS construction with latch-up protection against reverse currents
• Logic input tolerance allowing signal swing down to -5V for flexible interfacing

Applications

• Compact isolated power supplies
• Industrial motor control systems
• Power management IC interfaces

Procurement Notes

Verify the specific suffix 'TR' indicates reel packaging when reviewing distributor listings. Confirm the 16-SOIC package dimensions match the design footprint. Ensure the inverting logic configuration aligns with the system control requirements. Check moisture sensitivity levels if storage conditions exceed specified limits. Validate the operating temperature range against the intended environmental constraints.

Selection Notes

Select this component for applications requiring high-speed switching with significant drive current. The inverting configuration simplifies control logic integration where active-low signals are standard. Consider the 150°C junction temperature rating for high-thermal environments. The wide input voltage tolerance accommodates various logic families. Evaluate the 3A peak current against the target load capacitance requirements.

Part Context
