MIC4422ZN

Overview

The MIC4422ZN is a single-channel, low-side MOSFET gate driver manufactured by Microchip Technology in an 8-pin PDIP package. It delivers a peak output current of 9A for both sourcing and sinking. The device operates with a supply voltage range of 4.5V to 18V and supports logic input levels of 0.8V (low) and 3V (high). It features non-inverting input logic and provides fast switching characteristics with typical rise and fall times of 20ns and 24ns respectively. The component is rated for a junction temperature range of -40°C to 150°C.

Feature Summary

• Provides high peak drive current capability for rapid MOSFET switching
• Features non-inverting logic interface for direct control compatibility
• Designed for robust operation across extended industrial temperature ranges

Applications

• High-speed power conversion circuits
• Industrial motor control systems
• Inverter bridge driver stages

Procurement Notes

Verify the specific suffix 'ZN' corresponds to the PDIP-8 package variant when ordering. Confirm that the required operating temperature range aligns with the specified -40°C to 150°C junction limit. Ensure input logic voltage levels are compatible with the 0.8V/3V thresholds defined in the datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel, non-inverting low-side driver with 9A peak current is required. It is suitable for applications needing fast switching speeds within a 4.5V to 18V supply range. Consider the PDIP-8 package if through-hole mounting is necessary for the design constraints.

Part Context

This part belongs to the MIC4422 family of high-speed MOSFET drivers from Microchip Technology. It serves as a low-side driver solution, distinct from high-side or half-bridge variants. The 'ZN' suffix specifically denotes the plastic dual in-line package configuration, differentiating it from surface-mount options like ZM or YM.

Replacement Considerations

Compatible substitutes include other parts within the MIC4422 family such as MIC4422YM or MIC4422ZM, provided the package type matches the board layout requirements. Verify pinout compatibility and electrical parameters against the original datasheet before substitution.
