MIC4467CWM

Overview

The MIC4467CWM is a quad low-side MOSFET gate driver manufactured by Microchip Technology. It integrates four independent CMOS buffer drivers within a single SOIC-16 package, featuring a 2-input NAND logic gate for each output to enhance system flexibility. The device provides a peak output current of 1.2 A and operates on a supply voltage range of 4.5 V to 18 V. It exhibits symmetrical rise and fall times of 25 ns with a propagation delay of 75 ns. Designed for commercial applications, it functions reliably between 0°C and +70°C.

Feature Summary

• Integrates four high-power low-side drivers with dedicated 2-input NAND logic gates per channel
• Provides robust 1.2 A peak drive capability suitable for highly capacitive loads
• Features latch-up resistant design capable of tolerating ground line noise spikes
• Supports rail-to-rail voltage swings for efficient switching performance

Applications

• Driving power MOSFETs in motor control circuits
• Switching heavily loaded clock lines
• Driving coaxial cables and piezoelectric transducers
• Replacing multiple single-input driver packages to reduce component count

Procurement Notes

Verify the specific suffix 'CWM' against the manufacturer's latest documentation to confirm pinout compatibility and lead-free status. Confirm that the commercial temperature grade meets your operational requirements. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when a compact solution for driving multiple low-side MOSFETs is required. The integrated NAND gates allow for direct logic control without external components. Ensure the application stays within the 4.5 V to 18 V supply range and does not exceed the 1.2 A peak current limit.

Part Context

This part belongs to the MIC4467/4468/4469 family of quad CMOS buffer/drivers. While functionally related to earlier single- and dual-output drivers, this series utilizes the increased pin count to add logic gates. It shares the same core drive characteristics as other members of the family but differs in its specific input logic configuration.

Replacement Considerations

MIC4467ZWM is a documented direct replacement offering lead-free compliance.
