MIC4129YME-TR

Overview

The MIC4129YME-TR is a single-channel, low-side MOSFET gate driver manufactured by Microchip Technology. It features an inverting logic input and supports supply voltages from 4.5V to 20V. The device delivers a peak output current of 6A for both sourcing and sinking operations. Typical rise and fall times are 12ns and 13ns, respectively. Logic thresholds are defined at 0.8V (VIL) and 2.4V (VIH). It operates within a junction temperature range of -40°C to 125°C and is housed in an 8-SOIC package with an exposed pad.

Feature Summary

• Provides high-current drive capability suitable for power switching applications
• Features fast switching speeds with nanosecond-level transition times
• Includes inverting logic functionality for signal control
• Designed for robust operation across extended industrial temperature ranges

Applications

• Low-side MOSFET switching in power supplies
• Motor control circuits requiring high-speed drive
• Industrial power management systems

Procurement Notes

Verify the specific package variant, as MIC4129YML-TR denotes an MLF package while this model uses SOIC. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure moisture sensitivity level handling procedures are followed during assembly. Validate that the inverting logic configuration aligns with the system design requirements before procurement.

Selection Notes

Select this component when a single-channel, low-side driver with 6A peak current is required. The inverting input characteristic must be considered for logic interface compatibility. Compare against non-inverting variants if signal phase alignment is critical. Ensure the 4.5V to 20V supply range meets the system voltage constraints. Verify thermal performance within the 8-SOIC exposed pad package for the intended application environment.

Part Context

This part belongs to the MIC4129 series of improved high-speed MOSFET drivers. It shares functional similarities with other members like MIC4129YML-TR but differs in packaging. The series is designed for efficient power conversion and motor control applications. Microchip Technology continues support for this line following its acquisition of Micrel components.

Replacement Considerations

MIC4129YML-TR serves as a pin-compatible alternative with identical electrical specifications but utilizes an 8-MLF package instead of 8-SOIC. Verify footprint compatibility on the PCB layout before substitution. Other MIC412x series devices may offer different channel counts or current ratings.
