MIC4424YWM-TR

Overview

The MIC4424YWM-TR is a low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent channels with non-inverting logic inputs, housed in a 16-SOIC surface-mount 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 rise and fall times are specified at 35ns each. The component supports TTL and CMOS logic levels, with input thresholds defined at 0.8V (VIL) and 2.4V (VIH). It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• High peak output current capability of 3A for driving power MOSFETs
• Robust BiCMOS construction providing latch-up protection against reverse currents exceeding 500mA
• Logic inputs tolerate voltage swings down to -5V for enhanced noise immunity
• Non-inverting configuration with dual independent driver channels

Applications

• Low-side switching control for N-channel power MOSFETs
• General-purpose buffer and driver applications in power management circuits
• Industrial motor control systems requiring reliable gate drive signals

Procurement Notes

Verify the specific suffix 'YM' indicates the industrial temperature grade (-40°C to +85°C) and SOIC-16 package variant. Confirm the '-TR' designation corresponds to the tape-and-reel packaging format required for automated assembly processes. Ensure compatibility with the target PCB footprint dimensions for the 16-SOIC housing before finalizing procurement orders.

Selection Notes

Select this component when high peak current drive is necessary for low-side MOSFET applications. The 3A output capability exceeds standard logic gate limits, reducing switching losses. The wide supply voltage range accommodates various logic levels. Consider the 16-pin SOIC package for board space constraints compared to larger packages, while ensuring adequate thermal management for the specified power dissipation limits.

Part Context

This part belongs to the MIC4423/4424/4425 family of highly reliable BiCMOS DMOS drivers. These devices serve as higher output current versions of the MIC4426/4427/4428 series. All families in this lineage are pin-compatible, allowing for design flexibility. They are engineered to provide reliable service in demanding electrical environments compared to their predecessors.

Replacement Considerations

MIC4424YM-TR: Pin-compatible alternative available in 8-SOIC package with identical electrical specifications but different physical form factor.
