MIC4424BM-TR

Overview

The MIC4424BM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology, housed in an 8-pin SOIC surface-mount package. It delivers a peak output current of 3 A with non-inverting logic configuration. The device operates within a supply voltage range of 4.5 V to 18 V and supports TTL logic inputs. Typical switching performance includes a rise time of 28 ns and a fall time of 32 ns, with maximum on/off delay times of 33 ns. The component functions at temperatures between -40°C and +85°C, consuming 2 mA of operating supply current.

Feature Summary

• Dual-channel low-side driving capability with high 3 A peak output current for rapid power MOSFET switching
• Robust BiCMOS/DMOS construction providing latch-up protection against reverse current and noise spikes
• TTL-compatible logic inputs that remain independent of the supply voltage rail
• Rail-to-rail output voltage swings ensuring efficient drive with minimal power dissipation

Applications

• Driving power MOSFETs in demanding electrical environments requiring fast switching times
• General-purpose buffer and inverter applications for capacitive, resistive, or inductive loads
• Low-side gate drive circuits in power management systems and motor control interfaces

Procurement Notes

Verify the specific suffix 'BM' indicates the correct temperature grade and tape-and-reel packaging format required for your assembly process. Confirm RoHS compliance status as some variants may differ. Ensure the SOIC-8 footprint matches your PCB design guidelines. Check for moisture sensitivity level requirements during storage and handling prior to soldering.

Selection Notes

Select this component when a dual low-side driver with 3 A peak current is necessary for reliable MOSFET operation. It is suitable for designs requiring TTL logic compatibility without supply voltage dependency. Consider the 8-pin SOIC package for surface-mount assembly needs. Evaluate the thermal performance and operating temperature range against your system's environmental constraints.

Part Context

The MIC4424 series belongs to a family of highly reliable BiCMOS/DMOS buffer/driver/MOSFET drivers from Microchip Technology. These devices are higher output current versions of the MIC4426/4427/4428 series. All three families share pin compatibility, allowing for flexible design upgrades. The MIC4424 specifically offers non-inverting configurations optimized for low-side switching applications.

Replacement Considerations

MIC4424YM and MIC4424ZN are direct functional equivalents within the same family, offering identical electrical specifications but differing in package type (SOIC vs PDIP) and temperature rating.
