MIC4422ACM-TR

Overview

The MIC4422ACM-TR is a single-channel low-side MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.5V to 18V and delivers a peak output current of 9A for both sourcing and sinking. The device utilizes an 8-SOIC surface-mount package with a width of 3.90mm. It features non-inverting input logic compatible with 0.8V and 3V thresholds. Typical switching performance includes rise and fall times of 20ns and 24ns, respectively. The component supports junction temperatures from -55°C to 150°C.

Feature Summary

• Provides high-speed switching capabilities with 9A peak drive current for efficient MOSFET control
• Features non-inverting logic input configuration for direct signal interfacing
• Supports wide operating temperature ranges suitable for demanding industrial environments

Applications

• Low-side power switching in motor control systems
• Gate driving for power MOSFETs in DC-DC converters
• High-speed switching applications requiring fast transition times

Procurement Notes

Verify the specific suffix 'ACM' against official Microchip documentation to confirm the exact temperature grade and package variant. Confirm RoHS compliance status as some variants may differ. Check for obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a single-channel low-side driver with 9A peak current is required. Ensure the application voltage stays within the 4.5V to 18V range. Verify that the 8-SOIC package dimensions fit the PCB layout constraints. Consider thermal management requirements given the 150°C maximum junction temperature rating.

Part Context

This part belongs to the MIC4422 family of high-speed MOSFET drivers. It shares core specifications with other variants like MIC4422YM-TR but differs in package type and temperature rating. The family is designed for bipolar/CMOS/DMOS processes to provide robust gate drive performance.

Replacement Considerations

MIC4422YM-TR offers similar electrical characteristics in a different package variant. MIC4422AAM-TR provides comparable performance with potential differences in temperature grading. Verify pinout compatibility and thermal resistance values before substituting.
