MIC4428YMM

Overview

The MIC4428YMM is a dual low-side MOSFET gate driver manufactured by Microchip Technology in an 8-MSOP package. It operates on a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 1.5 A for both sourcing and sinking. The device features independent channels with inverting and non-inverting input configurations. Typical switching performance includes a rise time of 20 ns and a fall time of 29 ns. Logic thresholds are defined at 0.8 V for VIL and 2.4 V for VIH. The component supports junction temperatures from -40°C to 150°C.

Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• Integrated inverting and non-inverting logic inputs for flexible signal interfacing
• High-current drive capability supporting rapid switching transitions
• BiCMOS/DMOS construction ensuring high reliability and efficiency

Applications

• Low-side switching control for N-channel and P-channel MOSFETs
• Power management circuits requiring isolated or complementary drive signals
• Motor control systems utilizing dual independent gate drivers
• DC-DC converter topologies requiring fast turn-on and turn-off times

Procurement Notes

Verify the specific suffix 'YMM' confirms the 8-MSOP (3x3mm) package variant. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the required tape-and-reel or cut-tape format if applicable. Cross-reference the datasheet revision date to validate electrical specifications against current production versions.

Selection Notes

Select this component when dual independent low-side driving is required within a compact surface-mount footprint. The 1.5 A output current is suitable for standard power MOSFETs. The inclusion of both inverting and non-inverting outputs simplifies circuit design by eliminating external inversion logic. Verify that the 4.5 V minimum supply voltage aligns with the system's available logic levels.

Part Context

This device belongs to the MIC4426/4427/4428 family of dual low-side gate drivers. The MIC4428 specifically distinguishes itself by offering both inverting and non-inverting outputs, whereas other family members may offer different configuration combinations. All variants share similar electrical characteristics and manufacturing processes.

Replacement Considerations

MIC4428YM-TR: Identical functional specifications but housed in an 8-SOIC package instead of MSOP. MIC4428YMM: Same package and function, verify if TR suffix is required for reel packaging. MIC4427YMM: Dual low-side driver but typically offers different input/output logic configurations.
