MIC4422ZT

Overview

The MIC4422ZT is a single-channel, low-side MOSFET gate driver manufactured by Microchip Technology. It provides a peak output current of 9A and operates within a supply voltage range of 4.5V to 18V. The device features non-inverting logic input with rise and fall times of 25ns. It is housed in a TO-220 package designed for through-hole mounting. The component supports an operating temperature range from 0°C to +70°C and draws a typical quiescent supply current of 450µA.

Feature Summary

• Delivers high peak drive current for rapid switching
• Supports wide supply voltage operation
• Features fast transition times for efficiency

Applications

• Power supply circuits
• Motor control systems
• Inverter topologies

Procurement Notes

Verify the specific suffix ZT corresponds to the TO-220 through-hole package configuration. Confirm that the non-inverting logic level matches the system requirements. Ensure the thermal management design accommodates the power dissipation characteristics associated with the 9A peak current capability during switching events.

Selection Notes

Select this component when a robust through-hole solution is required for driving N-channel MOSFETs. The 9A output current ensures adequate gate charge delivery for medium-power applications. Consider the TO-220 form factor for ease of manual assembly or heatsinking compared to surface-mount alternatives.
