MIC4429CM-TR

Overview

The MIC4429CM-TR is a low-side MOSFET gate driver manufactured by Microchip Technology, housed in an 8-SOIC surface-mount package. It features a single channel with inverting input logic and supports supply voltages from 4.5V to 18V. The device delivers a peak output current of 6A for both sourcing and sinking. Typical rise and fall times are 12ns and 13ns respectively. Logic thresholds are defined at 0.8V for VIL and 2.4V for VIH. The operating junction temperature range extends from 0°C to 150°C.

Feature Summary

• Provides high-speed switching capability with typical transition times of 12ns rise and 13ns fall.
• Delivers robust 6A peak drive current suitable for driving power MOSFETs efficiently.
• Incorporates inversion protection to prevent unintended turn-on during fault conditions.

Applications

• Low-side switching control for N-channel and P-channel MOSFETs
• Power management circuits requiring fast transient response
• Industrial motor drive interfaces

Procurement Notes

Verify the specific suffix CM against the official Microchip datasheet to confirm the SOIC package variant and ensure it matches the required thermal and mechanical constraints. Confirm that the TR designation indicates reel packaging compatible with automated assembly processes. Cross-reference the RoHS status and MSL rating with current manufacturing notices to ensure compliance with project specifications.

Selection Notes

Select this component when a single-channel low-side driver with 6A peak current is required. Ensure the application voltage remains within the 4.5V to 18V supply range. Verify that the inverting logic interface aligns with the control signal source. Consider the 8-SOIC package dimensions for PCB layout compatibility and thermal dissipation requirements under continuous operation.

Part Context

This part belongs to the MIC4429 family of high-current gate drivers designed for bipolar/CMOS/DMOS processes. It serves as a dedicated interface between logic controllers and power switches. The MIC4429CM-TR specifically denotes the commercial temperature grade variant in an SOIC package, distinguishing it from other package options like MSOP or MLF found in related product lines.

Replacement Considerations

MIC4429YMM-TR is a verified substitute offering identical electrical performance but utilizes an 8-MSOP package instead of 8-SOIC. Verify footprint compatibility before substitution. No other direct functional equivalents are confirmed in the provided documentation.
