MIC4422AAM-TR

Overview

The MIC4422AAM-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 peak output currents of 9A for both sourcing and sinking. The device features non-inverting logic inputs with defined thresholds of 0.8V and 3V. Typical rise and fall times are 20ns and 24ns, respectively. It is housed in an 8-SOIC surface-mount package and supports junction temperatures from -55°C to 150°C.

Feature Summary

• Provides high-current drive capability suitable for fast-switching power MOSFETs
• Operates with standard CMOS and TTL logic input levels
• Designed for robust performance across extended industrial temperature ranges

Applications

• DC-DC converter circuits requiring efficient low-side switching
• Motor control systems utilizing N-channel MOSFETs
• Power supply designs needing isolated or non-isolated gate driving

Procurement Notes

Verify component authenticity through authorized channels as the part status indicates discontinuation at major distributors. Confirm that the specific suffix matches the required package and temperature grade. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure storage conditions account for moisture sensitivity levels before reflow soldering processes.

Selection Notes

Select this component when a single low-side driver with high peak current is required. Compare against the MIC4421 series if an inverting configuration is needed instead. Consider the operating temperature range and package constraints relative to the PCB layout. Verify that the supply voltage remains within the specified limits during all operational phases.

Part Context

This part belongs to the MIC4422 family of high-speed MOSFET drivers. It shares functional similarities with other variants like the MIC4422YM-TR but differs in packaging and temperature specifications. The AAM suffix denotes the specific 8-SOIC package variant. Understanding the family hierarchy helps in identifying compatible pinouts and electrical characteristics across different revisions.

Replacement Considerations
