MIC4128YME-TR

Overview

The MIC4128YME-TR is a low-side dual MOSFET gate driver manufactured by Microchip Technology. It features two independent drivers with inverting and non-inverting inputs, housed in an 8-SOIC-EP package. The device operates within a supply voltage range of 4.5 V to 20 V and delivers a peak output current of 1.5 A. Typical rise and fall times are 20 ns and 18 ns, respectively. It supports logic levels of 0.8 V (VIL) and 2.4 V (VIH). The component functions reliably across a junction temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel architecture providing independent inverting and non-inverting drive paths for flexible control configurations.
• High-current capability delivering 1.5 A source and sink currents to efficiently switch N-channel MOSFETs.
• Integrated thermal protection mechanisms designed to safeguard the device during transient overload conditions.

Applications

• Low-side switching control in DC-DC converter topologies
• Motor drive circuits requiring isolated or complementary gate signals
• Power management systems utilizing high-speed MOSFET actuation

Procurement Notes

Verify the specific suffix and packaging configuration against official Microchip documentation to ensure compatibility with surface-mount assembly processes. Confirm moisture sensitivity level handling requirements prior to installation. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability. Ensure the selected variant matches the required lead-free and RoHS compliance standards for your manufacturing environment.

Selection Notes
