MIC4428YMM-TR

Overview

The MIC4428YMM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology in an 8-pin MSOP package. It provides independent inverting and non-inverting outputs with peak source/sink currents of 1.5 A. The device operates on a supply voltage range of 4.5 V to 18 V, supporting logic inputs with thresholds of 0.8 V (VIL) and 2.4 V (VIH). Typical switching characteristics include a rise time of 20 ns and a fall time of 29 ns. It functions within a junction temperature range of -40°C to 150°C.

Feature Summary

• Dual-channel architecture providing independent inverting and non-inverting output configurations for flexible control schemes.
• High-speed switching performance with nanosecond-level rise and fall times to minimize transition losses.
• Robust drive capability delivering 1.5 A peak current to efficiently charge and discharge MOSFET gates.

Applications

• Low-side switching control for N-channel and P-channel power MOSFETs
• DC-DC converter synchronous rectifier drivers
• Motor control interface circuits

Procurement Notes

Verify the specific suffix 'YMM' corresponds to the 8-MSOP (3x3mm) package and 'TR' indicates tape-and-reel packaging. Confirm RoHS compliance status and ensure the operating temperature range meets system requirements. Cross-reference the manufacturer part number with official Microchip documentation to validate pinout and electrical specifications before integration.

Selection Notes

Select this component when dual isolated or complementary gate signals are required from a single input source. The 1.5 A drive current suits medium-power MOSFET applications. Ensure the PCB layout accommodates the MSOP footprint and thermal dissipation needs. Verify that the input logic levels align with the controller's output voltage standards.

Part Context

This part belongs to the MIC4426/4427/4428 family of high-speed MOSFET drivers. While the MIC4426 offers a single inverting channel and the MIC4427 provides two inverting channels, the MIC4428 uniquely combines one inverting and one non-inverting output. This configuration simplifies half-bridge driving without external phase-splitting components.

Replacement Considerations

MIC4426YM-TR: Single inverting channel only. MIC4427YM-TR: Dual inverting channels. MIC4428YM-TR: Same functionality but in SOIC-8 package instead of MSOP.

FAQ
