MIC4422ACN

Overview

The MIC4422ACN is a high-speed, low-side MOSFET driver manufactured by Microchip Technology. It features a single channel with a totem-pole output stage capable of delivering a peak output current of 9A. The device operates within a supply voltage range of 10V to 18V and supports input logic levels compatible with standard CMOS and TTL outputs. It is housed in an 8-pin PDIP package designed for through-hole mounting. The component functions as a non-inverting gate driver, providing fast rise and fall times to minimize switching losses in power applications.

Feature Summary

• Delivers high peak output current for rapid MOSFET switching
• Features a robust totem-pole output structure
• Supports wide supply voltage operation up to 18V
• Compatible with standard digital logic inputs

Applications

• Power supply circuits requiring efficient gate drive
• Motor control systems utilizing MOSFET bridges
• Industrial automation inverters
• High-frequency DC-DC converters

Procurement Notes

Verify the specific suffix 'CN' corresponds to the PDIP package variant when sourcing. Confirm the 'A' grade designation matches required temperature specifications. Ensure the supplier provides official datasheets to validate pinout and electrical characteristics against the manufacturer's documentation before integration into designs.

Selection Notes

Select this component for applications requiring a single-channel, non-inverting driver with high current capability. It is suitable for driving N-channel MOSFETs where fast switching speeds are critical. Consider the PDIP package constraints for board space and thermal management compared to surface-mount alternatives like the ZM series if PCB real estate is limited.

Part Context

This part belongs to the MIC4422 family of high-speed MOSFET drivers from Microchip. The family includes variants with different packages such as SOIC (ZM) and DIP (YN). The ACN variant specifically denotes the commercial temperature grade and PDIP packaging, distinguishing it from industrial or automotive qualified versions within the same functional lineup.

Replacement Considerations

Direct substitutes include other MIC4422 variants with different package footprints, such as MIC4422ZN or MIC4422YM, provided the PCB layout accommodates the package change. Cross-brand replacements require verification of peak current ratings, propagation delay, and supply voltage compatibility.
