MIC4467CWM TR

Overview

The MIC4467CWM TR is a quad low-side MOSFET gate driver from the Microchip Technology MIC4467 series. It integrates four independent CMOS buffer drivers within a single package to reduce system cost and improve reliability. The device operates with a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 1.2 A. It features symmetric rise and fall times of 25 ns, ensuring fast switching performance. The component is housed in a 16-SOIC surface-mount package and is designed for driving highly capacitive loads such as power MOSFETs.

Feature Summary

• Integrates four independent low-side drivers in a single package to minimize board space and system complexity.
• Provides high peak output current capability suitable for driving power MOSFETs and other capacitive loads.
• Features fast switching characteristics with symmetric rise and fall times for efficient signal transmission.
• Includes built-in 2-input logic gates on each channel to add flexibility and reduce external logic requirements.

Applications

• Driving power MOSFETs in motor control circuits
• High-efficiency clock line buffering
• Coaxial cable driving applications
• Piezoelectric transducer excitation

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with required packaging and environmental standards. Confirm that the lead-free status aligns with project specifications. Check for any recent Product Change Notifications (PCN) regarding manufacturing site or material changes. Ensure the component meets RoHS compliance requirements for the target market. Validate availability status as distribution channels may vary.

Selection Notes

Select this component when a compact solution for multiple low-side switches is required. It is suitable for designs needing rail-to-rail voltage swings and high peak currents. Consider the 16-SOIC package constraints for thermal management. Evaluate the need for integrated logic gating to simplify circuit design. Compare operating temperature ranges if harsh environments are involved.

Part Context

This part belongs to the MIC4467/4468/4469 family of quad 1.2A-peak low-side MOSFET drivers. These devices expand upon earlier single- and dual-output driver families by offering four outputs in one package. The family is designed to replace multiple packages of single-input drivers, thereby reducing total system cost and improving overall reliability through component consolidation.

Replacement Considerations

Direct substitutes include the MIC4467ZWM and MIC4467YWM variants, which share similar electrical characteristics but differ in packaging type and operating temperature range. Verify pinout compatibility and logic configuration before substitution.
