MIC4126BME

Overview

The MIC4126BME is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It operates in an 8-pin SOIC package and provides independent control for two channels. The device is designed to drive N-channel power MOSFETs with a peak output current capability of 1.5A per channel. It functions as a low-side driver, meaning it connects the load to ground. The component is classified as obsolete and is no longer in active manufacturing.

Feature Summary

• Dual independent channel configuration for separate gate control
• Low-side driving topology suitable for common ground applications
• Integrated protection features against shoot-through conditions

Applications

• Wired networking equipment
• Industrial transport systems excluding cars and light trucks
• Portable electronic devices

Procurement Notes

Verify availability status carefully as this part number is officially listed as obsolete by the manufacturer. Sourcing may only be possible through surplus distributors or secondary markets. Confirm lot dates and authenticity rigorously. Evaluate direct substitute options such as the MIC4126YME for new designs to ensure long-term supply chain stability and compliance with current production standards.

Selection Notes

Select this component only if legacy compatibility is required for existing PCB layouts using the 8-SOIC footprint. Ensure the application utilizes a low-side switching architecture where the source terminal is grounded. Verify that the 1.5A peak current rating meets the gate charge requirements of the target MOSFETs. Consider thermal dissipation capabilities within the SOIC package for continuous operation scenarios.

Part Context

This device belongs to the MIC412x series of gate drivers from Microchip Technology. It shares functional similarities with other members like the MIC4120 and MIC4126YME. The series focuses on providing robust gate drive signals for power management applications. The specific BME suffix denotes the package type and temperature range specifications defined by the manufacturer.

Replacement Considerations

The MIC4126YME is identified as a direct substitute available from Microchip Technology. This alternative offers similar functionality but may differ in packaging or lifecycle status. Verify pin-to-pin compatibility before implementation. Other cross-references exist but require careful validation of electrical parameters and physical dimensions.
