MIC4421ZT

Overview

The MIC4421ZT is a high-speed, low-side single inverting MOSFET gate driver manufactured by Microchip Technology. It provides a peak output current of 9 A and operates within a supply voltage range of 4.5 V to 18 V. The device features a rise time of 25 ns and a fall time of 25 ns. It is housed in a TO-220 package with through-hole mounting. The operational temperature range extends from 0°C to +70°C.

Feature Summary

• High-speed switching capability for efficient power device control
• Robust 9 A peak output current drive strength
• Inverting logic configuration for signal compatibility

Applications

• Driving IGBT power devices
• Driving N-Channel MOSFET power devices
• High-speed gate drive circuits

Procurement Notes

Verify the specific suffix 'ZT' corresponds to the TO-220 package and industrial temperature range (0°C to +70°C) required for your design. Confirm RoHS compliance status via the manufacturer's official documentation before procurement. Ensure the inverting configuration aligns with your control logic requirements.

Selection Notes

Select this component when a low-side driver with 9 A peak current is needed for IGBT or N-Channel MOSFET applications. The TO-220 package suits designs requiring through-hole assembly and adequate thermal dissipation. Verify that the 0°C to +70°C operating range meets environmental constraints.

Part Context

This part belongs to the MIC4421 series of high-speed MOSFET drivers. It is functionally similar to other variants like the MIC4421AYN but differs in package type (TO-220 vs. PDIP-8) and temperature rating. The ZT suffix specifically denotes the TO-220 packaging format.

Replacement Considerations

Direct substitutes include MIC4421AZT, which shares the same electrical characteristics and TO-220 package. Other family members like MIC4422ZT offer non-inverting configurations.
