MIC4422ABM

Overview

The MIC4422ABM is a high-performance, low-side MOSFET driver manufactured by Microchip Technology. It utilizes a Bipolar/CMOS/DMOS process to deliver a typical peak output current of 9A. The device operates within a wide supply voltage range of 4.5V to 18V. Key electrical characteristics include a typical propagation delay of 15ns and an equivalent input capacitance of 7pF. It features non-inverting logic input and a totem-pole output structure. The component is designed for surface-mount installation in an 8-pin SOIC package.

Feature Summary

• Delivers high peak output current capability for rapid MOSFET switching
• Utilizes Bipolar/CMOS/DMOS process technology for robust performance
• Features low equivalent input capacitance to minimize drive requirements
• Provides wide operating supply voltage range compatibility

Applications

• Industrial motor control systems
• Power management circuits
• High-speed gate driving applications

Procurement Notes

Verify the specific suffix (e.g., ABM) against official Microchip documentation to confirm pinout, temperature grade, and package dimensions. Ensure the source provides valid traceability for the original manufacturer designation. Cross-reference datasheet revisions to confirm parameter consistency before integration into design specifications.

Selection Notes

Select this component when a single-channel, non-inverting low-side driver with high peak current is required. The 9A peak current rating supports fast-switching power MOSFETs. Verify that the application voltage remains within the 4.5V to 18V operational window. Consider thermal dissipation requirements associated with the SOIC-8 package under continuous load conditions.

Part Context

The MIC4422 series comprises low-side MOSFET drivers from Microchip Technology, formerly Micrel. Variants such as MIC4422YMTR or MIC4422ZN share similar functional architectures but may differ in packaging, temperature ratings, or tape-and-reel configurations. The ABM variant specifically denotes the industrial temperature range and SOIC-8 package configuration within this product family.

Replacement Considerations

Direct substitutes include other MIC4422 variants like MIC4422ABM-TR for reel packaging. Verify pin compatibility and electrical parameters against the target application requirements before substitution.
