MIC4467ZWM-TR

Overview

The MIC4467ZWM-TR is a quad low-side MOSFET gate driver manufactured by Microchip Technology. It features four independent inverting drivers with a peak output current of 1.2 A. The device operates within a supply voltage range of 4.5 V to 18 V and utilizes a 16-lead SOIC wide package. Key electrical parameters include rise and fall times of 25 ns, and maximum on/off delay times of 75 ns. It functions at temperatures from -40°C to +85°C with a power dissipation rating of 1.5 W.

Feature Summary

• Integrates four high-power CMOS buffer drivers into a single package for system reliability
• Includes dedicated two-input logic gates for each channel to enhance design flexibility
• Capable of driving highly capacitive loads such as power MOSFETs with rail-to-rail swings
• Provides fast switching times suitable for heavily loaded clock lines and coaxial cables

Applications

• Driving power MOSFETs and similar highly capacitive loads
• Driving heavily loaded clock lines
• Driving coaxial cables
• Driving piezoelectric transducers

Procurement Notes

Verify the specific suffix ZWM-TR confirms the 16-lead SOIC Wide package and tape-and-reel packaging quantity of 1000 units. Ensure the component matches the Microchip Technology manufacturer identification rather than legacy Micrel branding found in older documentation. Confirm RoHS compliance status through official datasheets before procurement.

Selection Notes

Select this component when a compact solution for four independent low-side drivers is required. It is suitable for applications needing high peak current capability and integrated logic gating to reduce external component count. Consider the 16-lead SOIC package constraints and thermal dissipation limits relative to the expected load capacitance and switching frequency.

Part Context

This part belongs to the MIC4467/4468/4469 family of quad 1.2A-peak low-side MOSFET drivers. It expands upon earlier single- and dual-output driver designs by utilizing available pin count to add two-input logic gates per channel. This integration allows one package to replace multiple single-input driver packages and associated logic circuitry.
