MIC4426YM-TR

Overview

The MIC4426YM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent inverting channels designed for driving N-channel and P-channel MOSFETs. The device operates within a supply voltage range of 4.5V to 18V. It delivers a peak output current of 1.5A for both sourcing and sinking. Typical switching characteristics include a rise time of 20ns and a fall time of 29ns. Logic input thresholds are defined at 0.8V for VIL and 2.4V for VIH. The component is housed in an 8-SOIC package with a width of 3.90mm and supports an operating junction temperature range from -40°C to 150°C.

Feature Summary

• Dual independent channel configuration for simultaneous low-side drive applications
• Inverting logic input type compatible with standard digital interfaces
• BiCMOS/DMOS fabrication process optimized for low power consumption and high efficiency

Applications

• Low-side MOSFET switching in power management circuits
• Gate driving for N-channel and P-channel power transistors
• Industrial motor control systems requiring isolated or non-isolated low-side drive

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as MIC4426YM-TR denotes the SOIC package while other suffixes indicate MSOP. Confirm RoHS compliance status and MSL rating against the latest manufacturer datasheet revision. Ensure the supplier provides traceability documentation consistent with Microchip Technology standards. Cross-reference the part number with official distributor catalogs to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when a dual low-side driver with inverting logic is required for N-channel or P-channel MOSFETs. The 1.5A peak current capability suits moderate-power switching applications. Consider the 4.5V to 18V supply range for compatibility with various logic levels. The wide operating temperature range supports industrial environments. Verify that the 8-SOIC package dimensions fit the PCB layout constraints compared to alternative packages like MSOP.

Part Context

The MIC4426 belongs to the MIC4426/7/8 family of gate drivers from Microchip Technology, formerly Micrel. This series includes variants with different configurations such as non-inverting or high-side options. The MIC4426 specifically targets low-side applications with dual independent channels. The TR suffix indicates tape and reel packaging for automated assembly processes.
