MIC4428ZM-TR

Overview

The MIC4428ZM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.5V to 18V and delivers a peak output current of 1.5A for both sourcing and sinking. The device features independent inverting and non-inverting inputs, with typical rise and fall times of 20ns and 29ns respectively. Designed for surface-mount installation, it is housed in an 8-SOIC package (3.90mm wide) and supports junction temperatures from -40°C to 150°C.

Feature Summary

• Provides dual independent low-side drive capability with distinct inverting and non-inverting input channels.
• Delivers high-speed switching performance with 1.5A peak source and sink currents.
• Supports robust operation across extended industrial temperature ranges up to 150°C junction temperature.

Applications

• Low-side MOSFET switching in DC-DC converters
• Motor control circuits requiring independent phase drive
• Industrial power management systems

Procurement Notes

Verify the specific suffix 'ZM' corresponds to the 8-SOIC package variant when ordering. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the trailing '-TR' indicates tape-and-reel packaging requirements for your assembly process. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Selection Notes

Select this component when dual independent low-side driving is required without high-side integration. The 1.5A peak current rating suits standard power MOSFETs. Consider the 8-SOIC footprint constraints against available PCB real estate. Verify that the 4.5V minimum supply voltage aligns with your logic level requirements.

Part Context

This part belongs to the MIC442x series of high-speed MOSFET drivers from Microchip Technology, formerly Micrel. The series includes variants like MIC4426, MIC4427, and MIC4428, differentiated by input configuration and channel count. The MIC4428 specifically offers dual outputs with mixed inversion types.

Replacement Considerations

MIC4428YM-TR is a direct equivalent with identical electrical specifications but utilizes an 8-SOIC package. MIC4428YMM-TR offers similar functionality in an MSOP-8 package. Verify pinout compatibility before substitution.

FAQ

What is the difference between the MIC4428ZM-TR and MIC4427ZM-TR?

The MIC4428ZM-TR provides both inverting and non-inverting outputs, whereas the MIC4427ZM-TR provides only non-inverting outputs. Both share the same 1.5A peak current and SOIC package.

Does the MIC4428ZM-TR include high-side driving capability?

No, the MIC4428ZM-TR is strictly a low-side gate driver. It does not support bootstrap or high-side switching configurations.
