MIC4420ZM

Overview

The MIC4420ZM is a single low-side MOSFET gate driver manufactured by Microchip Technology. It utilizes a Bipolar/CMOS/DMOS process to deliver a peak output current of 6A. The device operates within a supply voltage range of 4.5V to 18V and features non-inverting logic configuration. Key timing parameters include rise and fall times of 25ns, with maximum on and off delay times of 18ns. It is housed in an 8-SOIC package (3.90mm width) and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Delivers high peak output current for efficient MOSFET switching
• Utilizes mixed-signal process technology for robust performance
• Features non-inverting input logic for direct control compatibility

Applications

• Low-side power switching applications
• Industrial motor control systems
• Power supply circuits requiring fast switching speeds

Procurement Notes

Verify the specific suffix ZM corresponds to the standard tube packaging variant rather than the tape-and-reel TR version when sourcing. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power supply rails before procurement.

Selection Notes

Select this component for applications requiring a single-channel low-side driver with moderate speed and high current capability. Compare against the MIC4420YM if through-hole mounting is preferred, or the MIC4420YN for PDIP options. Consider the MIC4420ZM-TR variant if automated surface-mount assembly using tape-and-reel packaging is required for production volume.

Part Context

This part belongs to the MIC4420 series of single MOSFET drivers from Microchip Technology. The series includes variants such as MIC4420YM and MIC4420YN, offering different package styles including SOIC and PDIP. These drivers are designed for general-purpose power switching tasks where cost-effective, reliable gate drive is necessary.
