MIC4128YME

Overview

The MIC4128YME is a dual low-side gate driver manufactured by Microchip Technology, housed in an 8-pin SOIC package with an exposed pad. It provides independent inverting and non-inverting outputs capable of sourcing and sinking 1.5A peak current. The device operates on a supply voltage range of 4.5V to 20V and supports N-channel MOSFETs. It features fast switching times with typical rise and fall times of 20ns and 18ns respectively. The component functions within a junction temperature range of -40°C to 125°C and includes transient protection.

Feature Summary

• Provides dual independent channel drive with complementary inverting and non-inverting logic inputs for flexible control configurations.
• Delivers high peak output current capability of 1.5A to efficiently switch power MOSFETs.
• Incorporates internal transient protection mechanisms to enhance reliability during operation.

Applications

• Driving N-channel power MOSFETs in DC-DC converter circuits
• Low-side switching applications in motor control systems
• Power management modules requiring isolated or buffered gate signals

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and tape/reel specifications. Ensure the source is an authorized distributor to guarantee authenticity. Check for RoHS compliance status and moisture sensitivity level ratings relevant to your assembly process requirements before finalizing procurement.

Selection Notes

Select this component when a dual-channel solution with both inverted and non-inverted outputs is required for low-side driving. It is suitable for designs needing 1.5A drive strength within a 4.5V to 20V supply range. Consider the 8-SOIC-EP package for thermal performance and board space constraints compared to other available packages in the series.

Part Context

This part belongs to the MIC4126/27/28 family of gate drivers from Microchip Technology, formerly Micrel. These devices are designed for general-purpose low-side switching applications. The MIC4128 specifically offers complementary outputs, distinguishing it from single-output variants in the same product line.

Replacement Considerations

Consult official substitution lists for equivalent parts within the MIC4126/27/28 family. Verify pin compatibility and electrical parameters such as drive current and operating voltage before replacing with alternative manufacturers' components.
