MIC4422ZM

Overview

The MIC4422ZM is a high-speed, low-side MOSFET gate driver manufactured by Microchip Technology. It features a single-channel non-inverting output configuration housed in an 8-pin SOIC package. The device delivers a peak output current of 9A, enabling rapid switching of power MOSFETs. It operates within a supply voltage range of 4.5V to 18V and supports input logic levels compatible with standard CMOS and TTL interfaces. The component is designed for applications requiring fast rise and fall times to minimize switching losses.

Feature Summary

• Provides high peak output current capability for efficient MOSFET switching
• Features a single-channel non-inverting topology for direct drive applications
• Supports wide supply voltage operation for various power system requirements

Applications

• High-frequency DC-DC converter circuits
• Motor control systems requiring low-side switching
• Power supply inverters and bridge configurations

Procurement Notes

Verify the specific suffix 'ZM' corresponds to the SOIC-8 tube packaging variant when sourcing. Confirm RoHS compliance status and lead time availability directly with authorized distributors or the manufacturer. Ensure the ordering part number matches the required package style and environmental specifications for your production line.

Selection Notes

Select this component for designs requiring a single low-side driver with high current capacity. It is suitable for replacing older Micrel-branded equivalents in existing schematics. Consider thermal dissipation requirements due to the 9A peak current capability. Ensure the PCB layout accommodates the SOIC-8 footprint and adequate copper area for heat management during high-current switching events.

Part Context

This device belongs to the MIC4422 family of high-speed MOSFET drivers. It serves as a successor to earlier versions produced under the Micrel brand following Microchip's acquisition. The ZM suffix specifically denotes the SOIC-8 surface-mount package with tube packing. It complements other variants like the YMTR (tape and reel) and AZM series components within the same functional family.

Replacement Considerations
