MIC4467ZWM

Overview

The MIC4467ZWM is a low-side gate driver from Microchip Technology, designed for driving N-channel and P-channel MOSFETs. It features four independent channels with an inverting configuration. The device operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 1.2 A. Key timing parameters include rise and fall times of 25 ns, with maximum on/off delays of 75 ns. It functions at temperatures between -40°C and +85°C and is housed in a 16-SOIC package.

Feature Summary

• Provides four independent low-side drive channels for power switching applications
• Capable of driving both N-channel and P-channel MOSFETs with high peak output current
• Features fast switching characteristics with 25 ns rise and fall times
• Operates with an inverting logic configuration across a wide supply voltage range

Applications

• Driving N-channel and P-channel MOSFETs in power circuits
• Low-side switching applications requiring independent channel control
• Power management systems utilizing CMOS logic interfaces

Procurement Notes

Verify the specific suffix ZWM confirms the 16-SOIC surface-mount package and industrial temperature range (-40°C to +85°C). Ensure compatibility with the required PCB footprint and soldering profile for SOIC-16 components. Confirm that the inverting configuration aligns with the system's logic requirements before procurement.

Selection Notes

Select this component when four independent low-side drivers are needed for mixed N/P-channel MOSFET loads. The 1.2 A peak current supports moderate-power switching tasks. The 16-SOIC package suits surface-mount assembly processes. Verify that the 4.5 V to 18 V supply range matches the available system voltage rails and that the inverting logic does not require additional inversion stages.

Part Context

This part belongs to the MIC4467 series of Power Logic CMOS Quad Drivers. It shares core electrical specifications with variants like the MIC4467ZN (PDIP) and MIC4467YWM-TR (SOIC, tape & reel), differing primarily in packaging type and manufacturing lot handling. The ZWM suffix specifically denotes the tube-packaged SOIC version.

Replacement Considerations

• MIC4467YWM-TR
• MIC4467ZN
