MIC4429BMM-TR

Overview

The MIC4429BMM-TR is a low-side MOSFET gate driver manufactured by Microchip Technology. It features a single inverting channel with a peak output current of 6A for both sourcing and sinking. The device operates within a supply voltage range of 4.5V to 18V. Typical switching times include a rise time of 12ns and a fall time of 13ns. Input logic thresholds are defined at 0.8V for VIL and 2.4V for VIH. The component is housed in an 8-MSOP surface-mount package and supports an operating junction temperature range from -40°C to 150°C.

Feature Summary

• Provides high-speed switching capability with typical rise and fall times under 15 nanoseconds.
• Delivers a robust 6A peak output current to efficiently drive power MOSFETs.
• Features an inverting input configuration for standard logic interface compatibility.

Applications

• Power management systems requiring efficient low-side switching
• DC-DC converter circuits utilizing N-channel or P-channel MOSFETs
• Motor control applications driving low-side power stages

Procurement Notes

Verify the specific suffix BMM-TR corresponds to the 8-MSOP package and tape-and-reel packaging format. Confirm that the manufacturer designation aligns with Microchip Technology, noting historical transitions from Micrel. Ensure the component meets RoHS3 compliance standards as documented in official datasheets. Cross-reference the full part number against distributor catalogs to confirm availability status and lead times prior to ordering.

Selection Notes

Select this component when a single-channel low-side driver with 6A peak current is required. The inverting logic configuration must match the control signal polarity. Consider the 8-MSOP package size for space-constrained PCB layouts. Verify that the supply voltage range of 4.5V to 18V accommodates the system requirements. Ensure the operating temperature range extends to 150°C if thermal conditions are demanding.

Part Context

The MIC4429 series belongs to Microchip's family of high-performance MOSFET gate drivers. This specific variant integrates bipolar/CMOS/DMOS technology to achieve fast switching speeds.
